_ Chapter 1: so, Your Printer

If the rear panel of your printer looks like Figure 1-1, you must power your printer from a 120 volt AC, 50/60 Hz, outlet. If the rear panel of your printer looks like Figure 1-2, the required line voltage is visible through the small window in the cover of the fuse box. Printers with a rear panel such as Figure 1-2 can be configured to operate from several different line voltages. € If you need to change the fuse in your printer or configure it for a different

line voltage, refer to the instructions in Appendix E.

WARNING

Your printer may be damaged if you attempt to power it from an incorrect voltage.

To connect the printer to a power outlet, plug one end of the power cord into € the receptacle on the rear panel of the printer and plug the other end into an

appropriate outlet.

Mode Select Switches

On the rear panel of your printer there are 8 switches which allow you to configure your printer so that it will work with almost any computer sys- tem. These switches are numbered from 1 (closest to the power switch) to 8 (farthest from the power switch).

Table 1-1 contains switch settings for several computer systems. If your é computer system is not ‘ncluded in the table, or the format of your printouts ‘SS is incorrect, refer to Appendix A.

NOTE The printer reads the switch settings only when it is first turned on. Therefore if you change any of the switch settings, you must turn the printer off for several seconds and back on before printing.

You cannot damage your printer by setting the switches incorrectly.

Chapter 1: Setting Up oe

The mode select switches can be used to customize your printer for applica- tions such as languages other than English or 12” paper. See Appendix A for more details.

If switch 5 is up, your printer will work with most software which expects one of the following printers:

¢ Epson MX-80

¢ Epson MX-100

¢ IBM 80 CPS Printer

¢ IBM Graphics Printer

If switch 5 is down, your printer will work with most software which either does not specify a printer or specifies a Hewlett-Packard printer. ©

Connecting the Printer Cable

To use your printer with your computer, your computer must be equipped with a parallel printer interface port. You should have obtained a printer cable with either your computer or your parallel printer interface card. If

ou do not have a printer cable for your computer, contact your Hewlett- Packard dealer or an authorized sales representative.

Insert the end of your printer cable into the connector on the rear panel of , your printer and snap the two wire clips of the printer connector onto the - end of the cable as shown in Figure 1-3.

NOTE The attention light also blinks if there is paper in the printer and one of the following conditions is present:

Form Feed Button

The form feed button advances the paper to the next page. The exact position to which the paper advances is called the “top of form.”

¢ The printer is performing the internal self test immediately after power is turned on.

NOTE If your printer is not correctly set for the length of paper you are using, the form feed button may not advance the paper the distance you expect. If you need instructions on setting the printer for your length of paper, see pages 2-8 and A-3.

¢ A self test error was detected.

Printing Self Test

You can now verify that the printer is operating correctly by using the printing self test. First turn the printer off. Then depress and hold the line ( é feed button while turning the printer on. Release the line feed button to start ™® the self test sequence, which includes a set of printed examples. You can terminate the self test at any time by turning the-printer off.

Setting Top of Form a Top of form is set to the current line each time the printer is turned on or the q blue button (the top button on the control panel) is pushed.

Normally you should set top of form to the fourth line on the page, which will leave a top margin of 2". To set top of form to the fourth line, use the line feed button to position the paper so that the perforation is just above the pinch rollers, and press the blue button.

WARNING The carriage should be against the left side of the printer whenever the printer is off. If the carriage remains in the center of the page for prolonged periods, it is possible for the print head face to come in contact with the paper, causing ink to wick out of the print head cartridge.

Some software packages instruct you to set top of form to the first line of the page. To do this, use the line feed button to position the paper so that the perforation 1s approximately “4° (6 mm) below the pinch rollers, and press e€ the blue button. '

If the carriage is not at the left side of the printer, turn the printer on and wait for the carriage to move to the left side of the printer. Then turn the printer off.

NOTE If the printer runs out of paper while printing a document, it will stop automatically. After loading paper and positioning it, press the blue button. This will set top of form and instruct the printer to continue printing the document.

Ready to Print

The HP 2225C printer is now prepared for printing. For your convenience, it

is designed to print with 1” margins on each side of the page. If you want

larger margins, software packages such as word processors should have the / capability of increasing them. Other “default” (pre-set) printing specifica- c | tions are:

Attention (Yellow) Light Under normal operating conditions the yellow attention light is off. If the attention light is on, the printer 1s out of paper. After paper 1s loaded, the attention light begins flashing. Position the paper using the line feed button and then set top of form with the blue button. The attention light will turn off. The printer is now ready to print.

e 12 characters/inch ¢ 80 characters/line ¢ 6 lines/inch

You should now be able to use your printer with your computer system without reading any more of this manual. However, Chapters 2 and 3 explain how to use other print features such as underlining and bold mode, as well as change the default printing specifications listed above.

You should never move the carnage manually or obstruct its movement. If the printer detects that this has happened, it will stop printing. In this event, the print buffer empties, all print features return to their default settings, and the attention light begins flashing. To recover from this error state, remove any obstructions such as crumpled paper from around the carriage and push the blue button.

Chapter 2

Using Print Features

a ate Saisie

€ | The previous chapter told you how to set up and begin operating your HP 2225C printer. This chapter will tell you how to use the more commonly selected print modes and form control features: print pitches, bold mode, underlining, line spacing and perforation skip mode. Chapter 3 introduces more advanced print features. :

-_ Introduction to Control Codes and

<¢ Escape Sequences You may already have software which allows you to use many of the print features of your HP 2225C printer. If, however, you wish to use any of these print features on your own, the following two chapters provide you with examples of each of the print features and the data used to generate those examples.

Sy ie is sy OL vee? Teeny Von) Vom) oem

The print features of your printer are controlled by “control codes” and

“escape sequences.” Control codes are data that, when sent to your printer, /@- do not cause anything to be printed. They are commands which cause an ( action. An example of how control codes are written in this manual is [cTLN], which is pronounced “control N."

One of the control codes is named “escape,” which in this manual is written as [ESC]. Escape sequences consist of the control code followed by one or more other characters. For example, & k 1S is an escape sequence which changes the print pitch. None of the characters in an escape sequence is printed; together they forma command which is used to control a feature of your printer, just as a single control code is a command.

6

NOTE When reading this manual, be very careful to not confuse O (upper- case oh) with 0 (zero) or / (lowercase ell) with 1 (one).

Some features are controlled by both a mode select switch on the rear panel of the printer and an escape sequence. In these cases, the switch sets the default condition of the feature but the escape sequence will override the switch. If the printer is turned off and on, the feature will return to the

‘eq setting selected by the switch.

Chapter 2: oi Features Chapter 2: Using Print eo

If you are using a software package such as a word processor or spreadsheet, refer to your software documentation to learn how to represent control codes and escape sequences.

To generate printouts using these print features, you will need to become familiar with the method used by your computer or software to send escape sequences and control codes to your printer. Some of the different methods commonly used are:

If you are writing BASIC programs, you can generate control codes with the CHR ) function. For more information on the CHR3%( ) function, refer to a

¢ Typing escape sequences and control codes directly from the keyboard. BASIC programming manual.

Many computer keyboards have a key labeled and another key labeled TONS, Ceui8, or CGuGT8. When the key is pressed, it gener- ates the escape control code. Other control codes are generated by holding down the key while pressing a different key, Just as holding down the key while pressing another key generates special puncuation characters and uppercase characters. On some keyboards that do not have

an key, can be generated as(ctt [].

In this manual, CHR$( ) is used to specify numbers which are ASCII numbers, not characters. For example, 83 and CHR9$(83) are two different | things. The first, 83, is a string of two characters: 8 and 3. CHR$(83) is a |

single character, uppercase “S". ig

Control Sequence Modes

The HP 2225C printer has two different control sequence modes: HP Con- ‘i trol Sequence Mode (HP mode) and Alternate Control Sequence Mode (Alternate mode). The escape sequences and control codes which control the print features are different for the two modes. If the printer receives an escape sequence or control code which is invalid for the current mode, it will | either ignore the command or produce unexpected results. However, do not | be afraid of making mistakes. You cannot damage your printer with an |

NOTE If you are entering escape sequences in this manner, do not type any spaces between the characters of the escape sequence. In this man- ual spaces are sometimes inserted in the escape sequences for read- ability; they are not actually a part of the escape sequence.

- Specifying each control code, including [ESC], by its ASCII* number.

Some software packages require that you specify each control code by its ASCII number, usually preceded by a special character such as a ) For example, the escape sequence & k 1S would be specified as \027 & k 1S. Appendix D contains the ASCII representation of each control code.

invalid escape sequence.

Switch 5 on the rear panel of the printer determines which mode is currently 4 | being used. If switch 5 is down, the printer is in HP Control Sequence Mode; ai if switch 5is up, the printer is in Alternate Control Sequence Mode. Page A-3 | | discusses choosing the appropriate control sequence mode for your com- |

puter system. &§

¢ Specifying each character of the escape sequence by its ASCII number. 7 2 The following sections discuss both control sequence modes for each

print feature. For reference purposes, Appendix B lists all of the HP mode control sequences; the control sequences for Alternate mode are listed in Appendix C. |

Some software packages require that you specify and the characters following it by their ASCII numbers. The reference tables in Appendices B and C contain the ASCII representation of each escape sequence

& k1S is represented in ASCH €

As an example, the escape sequence as 27 38 107 49 83.

*The ASCII (American Standard Code for Information Interchange) charac- ter tables in Appendix D assign a number between 0 and 255 to every character or control code recognized by the printer. Computers use these numbers when storing and communicating text material. Unless specifi- cally noted otherwise, the numbers used in this manual are decimal num- bers. A few software packages require you to enter ASCII numbers in “hexadecimal.” The reference tables in Appendices B and C include the hexadecimal representation of each control code and escape sequence.

Perforation Skip

The HP 2225C printer is capable of automatically leaving top and bottom margins on every page. This is called “perforation skip mode” because,

them.

™

The printer does not sense the perforations in the paper; you must tell it where to put the margins by setting top of form as described on page 1-12. When you set top of form, you specify the position of the first line of print: the line immediately following the top margin. The default “perforation skip length” (combined length of the top and bottom margins) 1s 6 lines. If top of form is set to the fourth line of the page, the printer will leave a margin of three lines at the top and bottom of each page.

Figure 2-1 shows top of form set correctly for equal top and bottom margins.

If switch 5 is DOWN (HP mode):

The escape sequence & | 1L turns perforation skip mode on, & 10 L turns it off. These escape sequences override switch 3.

The perforation skip length is not specified directly. If you wish to use a value other than the default, you must specify a new ‘text length,” which is the number of lines to be printed on each page. The perforation skip length is the total length of each page minus the text length.

The escape sequence to set the text length is [ESC] & / # F, where # 1s the text length specified in number of lines. For example, the escape sequence & 154 F sets the text length to 54 lines. If the printer is set for a page length of 66 lines (11 inch paper, 6 lines per inch), the perforation skip length is 66 minus 54: 12 lines. To get equal top and bottom margins of 6 lines, top of form must be set to the seventh line of the page.

Text length cannot be less than one line nor greater than the page length. The escape sequence & 10 F will set the text length back to the default, which is 1 inch less than the page length.

If switch 5 is UP (Alternate mode):

The escape sequence N CHR$(#) sets the perforation skip length to # lines and turns perforation skip mode on. The number used to set the perforation skip length is the ASCII number associated with the character following “N.” For example, N 1 does not set perforation skip length to 1 line, the ASCII number for the character “1” is 48 (see Appendix D), so perforation skip length is set to 48 lines. To set the perforation skip length to 10 lines, look in Table D-1 of Appendix D and find that 10 is equivalent to [ctLJ |. Then use the escape sequence N [ctiJ].

The escape sequence O turns perforation skip mode off.

These escape sequences override switch 3.

Page Length

The HP 2225C printer allows you to change the page length. The current value of page length determines how far the printer advances the paper when the form feed button is pressed or the printer receives a form feed control code. The printer also uses the value of page length, when perfora- tion skip mode is on, to determine where to place the top and bottom margins.

Switch 4 on the rear panel of the printer selects the default page length. If switch 4 is down, page length defaults to 11 inches (279.4 mm), which is 66 lines at 6 lines per inch. If switch 4 is up, page length defaults to 12 inches (304.8 mm), which is 72 lines at 6 lines per inch.

The escape sequence & 1 # P sets the page length to # lines. For example, & 150 P sets the page length to 50 lines. This escape sequence

- overrides switch 4.

Page length can be set to any number of lines from 1 to 255. The escape sequence & 10 P will reset the page length to the default.

The page length escape sequence automatically sets the text length to 1 inch (6 lines at 6 lines per inch) less than the new page length.

If switch 5 is UP (Alternate mode):

The escape sequence C CHR$(#) sets the page length to # lines. The number used to specify the page length is the ASCII number associated with the character following “C.” For example, C 1 does not set page length to 1line. The ASCH number associated with the character “1” is 48, so page length is set to 48 lines. To set page length to 70 lines, look up 70 in Table D-1 of Appendix D and find that 70 is equivalent to the character ge Then use the escape sequence CE.

If switch 5 is DOWN (HP mode):

To print at 8 lines per inch, send the escape sequence & 18D. To return to 6 lines per inch, use & 16D.

If line spacing is changed, page length and text length measured in inches

remain the same. For example, if line spacing is 6 lines per inch and page length is 66 lines (11 inches), changing line spacing to 8 lines per inch will also change page length to 88 lines (11 inches).

More on Print Features

€ : * In the previous chapter we discussed the frequently used print features.

In this chapter we will discuss some advanced print features.

Positioning the Print on the Page

Some of the control codes and escape sequences change the position at which the next character received will be printed. This position 1s called the “current active position.” Each time the printer receives a printing character, the current active postion is moved one character to the right. The following control codes separate lines of print, cause the printer to overstrike charac- ters, or cause the printer to advance the paper.

Unless specifically noted otherwise, these control codes and escape

sequences are identical in HP mode (switch 5 down) or Alternate mode

(switch 5 up).

¢ Carriage Return ([cTLM] ): Moves the current active position to the first character position on the current line. Normally you do not need to send carriage returns explicitly; your computer system will send them automatically.

Fither switch 1 on the rear panel of the printer or the Automatic Line Termination escape sequence discussed on page 3-9 can cause the printer to perform a line feed in addition to each carriage return.

¢ Back Space ([ctLH)]): Moves the current active position one character to the left. If the current active position 1s already the leftmost character position, no action is taken.

. Line Feed ({ct.J ]): Advances the paper one line. Normally you do not need to send line feeds explicitly; your computer system will send them automatically.

Either switch 2 on the rear panel of the printer or the Automatic Line

Termination escape sequence discussed on page 3-9 can cause the printer to perform a carriage return in addition to each line feed.

» Half Line Feed ([ESC] =): Advances the paper half the distance of the current line spacing.

This escape sequence is only valid if switch 5 is down (HP mode). If switch 5 is up (Alternate mode) you must change the line spacing and then send a line feed control code.

Chapter 3: mop Print Features

Half line feed is useful for printing subscripts and superscripts.

. Form Feed ({cT.L }): Advances the paper to the top of the next form.

“NOTE The printer cannot sense the actual position of the paper. For form feed to advance the paper to the next perforation, top of form must be set correctly as described on page 1-12.

Overstrike There are two methods of overstriking text:

¢ Sending two lines of text separated only by a carriage return. This causes the printer to print the second line over the first line.

This method will work only if carriage return does not perform a line feed (see Carriage Return on page 3-1). If carriage return does perform a line feed, you must use the back space method for overstriking.

- Using back space. Each time the printer receives a back space control code, ‘t moves the current active position one character position to the left before printing the next character. Therefore, if two characters are sent to the printer separated only by a back space, the second character is printed over

the first. , Graphics € Many computer systems allow you to draw graphs or pictures on your computer display using the computer's capabilities and a graphics software package. The computer then handles the details of copying the graphics data to the printer. You may, however, be interested in writing your own

graphics software program. The following information provides the details of the HP 2225C graphics capabilities. 4

3-2

Chapter 3: More On Print Features

The HP 2225C printer is capable of printing in two modes: text mode and graphics mode. In text mode, the printer interprets each data byte it receives from the computer as an ASCII character. It then looks that character up in ‘ts internal character table and prints the dot pattern which it finds. In

Me sraphics mode, however, the data received from the computer directly

specifies the dot pattern which is to be printed.

The HP 2225C uses a form of graphics called “dot-image” graphics. In this system, the paper can be thought of as consisting of a grid of dot positions. Graphics data specifies which of the dot positions should be printed and which should be left blank.

NOTE

Some computers automatically add control codes, such as carriage -eturns and line feeds, or blanks to the data being sent to the printer. These characters are necessary when printing text. In graphics mode, however, they may be interpreted as graphics data and give unex- pected results. Before writing programs which generate graphics, you should consult the manual for your computer to determine how to prevent your computer from sending this extra data to the printer.

If switch 5 is DOWN (HP mode):

é Graphics Density ® The HP 2225C is capable of printing graphics in two different dot densities.

The default dot density is 96 dots/inch in both the horizontal and vertical directions; the print region is 640 dots wide. The higher dot density 1s 192 dots/inch in the horizontal direction and 96 dots/inch in the vertical direc- tion; the print region is 1280 dots wide. The escape sequence used to select high density graphics is [ESC] *r 1280 S. To return to the default graphics density use «1640S. Once the graphics resolution 1s specified, it stays ‘n effect until it is explicitly changed or the printer is reset.

Raster Dot Row

& Graphics data is sent to the printer one byte (8 bits) at a time. Each bit

specifies one dot position. If a bit is zero, the corresponding dot position 1s left blank. Ifa bit is one, a dot is printed at the corresponding position. In HP mode, graphics data bytes are sent to the printer in groups, where each group contains the graphics data for one “raster” (horizontal) dot row. The first (most significant) bit of a graphics data byte specifies the leftmost dot, the last (least significant) bit specifies the rightmost dot.

3-3

Chapter 3: More On Print Features

The escape sequence to transfer the data for one dot row is *b #W. The value field, #, specifies the number of graphics data bytes which follow the escape sequence. For example, if the printer receives * b 20 VW, it interprets the next 20 bytes of data as specifying 160 dots (20 x 8 bits) of the current dot row. If less data is sent for a dot row than will fit in the print

region, the rightmost dots of the row are left blank. If more data is sent than will fit in the print region, the extra data 1s ignored.

Paper advance occurs automatically between graphics dot rows; it 1s not necessary to send any paper advance control codes.

Beginning and Ending Graphics Mode

If the printer has a partial line of text data in its buffer and it receives the raster dot row escape sequence, it terminates the line of text with a carriage 4 return (but no line feed), prints it, and then accepts the graphics data. This may cause the graphics data to be printed over the text data.

To avoid printing graphics over text, send the escape sequence *rA before sending any graphics data. This escape sequence causes any partial lines of text to be terminated with a carriage return and line feed. If there is no text in the buffer, this escape sequence has no effect.

When the printer receives graphics data, it places that data in its buffer. Normally the graphics data is not actually printed until the buffer contains 12 ce dot rows of default-density graphics or 6 dot rows of high-density graphics. é. To make sure all of the dot rows are printed and not still stored in the printer's buffer, send the escape sequence * r Bafter sending all of the graphics data.

Sample Graphics Program

The following is an example of a simple HP BASIC program which prints graphics.

Printer output:

You may need to modify this program to make it run correctly on your computer. To produce the preceding graphics example using Microsoft BASIC, Version A2.00, use the following program:

Description

| 20 WIDTH #1,255 Prevent the computer from

sending CR, LF 30 PRINT #1, CHR$(27) +” #16405"; Select default graphics density AQ PRINT #1, CHR$(27)+”*rA”; | Begin raster graphics

110 PRINT #1, CHR$(27)+”*1B” | Terminate raster graphics If switch 5 is UP (Alternate mode):

In Alternate mode, each byte of graphics data specifies an 8-dot high col- umn. The first (most significant) bit specifies the top dot of the column; the

. last (least significant) bit specifies the bottom dot of the column. If a bit is . zero, the corresponding dot position is left blank. If a bit is one, a dot is

printed at the corresponding position. | You can specify the horizontal distance between adjacent columns as either 1/96 inch or 1/192 inch. The escape sequence K #1 #2 selects default- density graphics (1/96 inch between columns), L #1 #2 selects high- density graphics (1/192 inch between columns).

Chapter 3: More ; n Print Features

The 2-byte value field (#1 and #2) specifies the number of following bytes which are to be interpreted as graphics data. #1 and #2 are not inter- preted as ASCII characters, they form a 16 bit binary number where #2 is

the most significant byte and #1 is the least significant byte. For example,

K CHR$(128) CHR$(1) specifies that the next 384 bytes (128 + (256 * 1)

= 384) of data are graphics dot columns which are to be printed 1/96 of an inch apart.

Before sending any graphics data, line spacing should be set to 8 dot rows by the A CHR$(8) escape sequence. After sending all of the graphics columns across one row, you must send a carriage return and line feed to the printer to cause it to advance the paper and return to the left margin.

Some computer systems do not have the capability of controlling the most | significant bit of data bytes sent to the printer. If your computer system always clears this bit, you can still print graphics by setting line spacing to 7 dot rows (by either 1 or A CHR3$(7)) before sending graphics data.

Selecting Unidirectional or Bidirectional Printing The HP 2225C printer normally prints text bidirectionally. You can get

slightly better alignment between lines of print by setting the printer to. print unidirectionally (left to right only).

If switch 5 is DOWN (HP mode):

The escape sequence & k 0 W will force unidirectional printing. To return to bidirectional text printing, use & k1W.

This escape sequence does not affect graphics printing; the printer always prints graphics unidirectionally. If switch 5 is UP (Alternate mode): eq

The escape sequence [ESC] U 1 will force unidirectional printing. To return to bidirectional text printing, use U 0.

This escape sequence does not affect graphics printing; the printer always prints graphics unidirectionally.

Chapter 3: More On Print oe”

End of Line Wrap-Around

If the printer is in wrap-around mode, the first character received which exceeds the line length of the printer forces a new line of print to be started. This causes long lines to be broken and printed as several lines. If the printer is not in wrap-around mode, characters which exceed the line length of the current print pitch are not printed.

If switch 5 is DOWN (HP mode):

The default 1s wrap-around mode disabled. The escape sequence & s 0 C enables wrap-around mode, & s 1 C disables wrap-

~ ground mode.

If switch 5 is UP (Alternate mode):

The printer is always in wrap-around mode; you cannot disable it.

Linking Escape Sequences If switch 5 is DOWN (HP mode):

You can link several escape sequences into one escape sequence string. For example, you can enable perforation skip mode and set line spacing

. to 8 lines per inch by entering either & 18 D and & 11L or y [ESC] & 18 d1L.

The two rules to follow when linking escape sequences are-

* The final character of the internal escape sequences becomes lower case. In the example above, D becomes d.

» If switch 5 is UP (Alternate mode):

It is not possible to link escape sequences, each one must be sent exactly as it is specified in this manual.

Display Functions Mode Control codes and escape sequences are not normally printed; they are either recognized as commands and cause some action or they are ignored.

The display functions mode allows you to print control codes and escape sequences without executing them. This is useful if you are trying to determine exactly what control codes and escape sequences are being sent to your printer. The symbol which is printed for each control code can be found in Table D-1 of Appendix D.

Potential for Radio/Television Interference

The HP 2225C printer generates and uses radio frequency energy and may cause interference to radio and television reception. Your printer complies with the specifications in Subpart J of Part 15 of the Federal Communications Commission rules for a Class B computing device. These specifications provide reasonable protection against such interference in a residential © installation. However, there is no guarantee that interference will not occur in a particular installation. If the printer does cause interference to radio or television reception, which can be determined by turning the printer off and on, you can try to eliminate the interference problem by doing one or more of the following:

¢ Reorient the receiving antenna.

- Reorient the position of the printer with respect to the receiver.

* Move the printer away from the receiver. :

- Plug the printer into a different outlet so that the printer and the receiver are on different branch circuits.

4 .

If necessary, consult an authorized HP dealer or an experienced radio/ television technician for additional suggestions. You may find the following booklet, prepared by the Federal Communications Commission, helpful: How to Identify and Resolve Radio/TV Interference Problems. This booklet is available from the U.S. Government Printing Office, Washington D. C.

If your computer system is not included in Table A-3, or the format of your printouts is incorrect, the following instructions will help you correctly configure your printer.

Before using these instructions, you must obtain some printout from your computer and printer. If you are going to use your printer with software such as a spreadsheet program or a word processor, use your software € generate some printout. Alternatively you may generate printout with a short BASIC program such as the following example.

10 FOR I = 17010

20 PRINT “This is a line of sample output for testing my printer. 30 NEXT I

40 END

If your printer does not respond to your computer at all, try setting switch 6 — on the rear panel of your printer up. If you still get no response, refer to the € owner’s manual for your computer or parallel printer interface card.

"NOTE The printer reads the switch settings only when it is first turned on. Therefore if you change any of the switch settings, you must turn the printer off for several seconds and back on before printing,

The switches are numbered from 1 (closest to the power switch) to8 from the power switch). The remainder of this section describes, | switch, conditions which may cause you to change the switch setting. if none of the conditions apply, leave the switch at its current setting.

Switch 1 - Carriage Return (CR) Definition If your printer does not advance the paper between lines of print, set switch 1 up. The printer will add a line feed to each carriage return it receives. . : If your printout is double spaced, set switch 1 down. The printer will not add | a line feed to each carriage return. Switch 2 - Line Feed (LF) Definition If some lines of your printout start too far to the right, or only the first line is printed, set switch 2 up. This causes the printer to add a carriage return to each line feed it receives.

If some lines of your printout start too far to the left, set switch 2 down. The printer will not add a carriage return to each line feed.

Switch 3 - Perforation Skip Mode

If you are listing programs or using software which does not provide top and bottom margins in your printout, set switch 3 up. This will put the printer in perforation skip mode. In this mode the printer automatically provides top and bottom margins.

If you do not want top and bottom margins or you are using software such as a word processor which already provides margins, set switch 3 down. This turns off perforation skip mode.

Ze, Switch 4 - Page Length 6: you are using 12” (304.8 mm) paper, set switch 4 up. This sets the printer's. page length to 12 inches (304.8 mm). If you are using 11” (279.4 mm) paper, set switch 4 down. This sets the printer's page length to 11 inches (279.4 mm).

Replacing the Fuse, international options

The fuse for the HP 2225C is located behind the cover of the fuse box. The fuse is in a carrier which slides into a cavity in the fuse box. There are two cavities for fuse carriers; one above the other. The fuse must be installed in the UPPER cavity. The white arrows on the inside of the fuse box cover point up, to the correct cavity.

The fuse box on the rear panel of the printer contains a voltage selector drum

for selecting one of the four line voltages. The line voltage your printer is set

for is visible through the small window in the cover of the fuse box.

selecting a Line Voltage, international options € Two fuse carriers can be used with the printer, one (white) for U.S. style : —_—_—— a : ——_—_——— —_—— fuses, and one (black) for European style fuses. The correct carrier for your

area was supplied with your printer. If you wish to use your printer witha

line voltage which requires the other fuse carrier, contact your local Hewlett-

Packard dealer or authorized sales representative. An unused carrier may be

stored in the lower cavity of the fuse box.

* Remove the power cord from the printer.

- Open the cover of the fuse box with a small screwdriver. The cover closes tightly but will yield to firm pressure.

e Pull out the voltage selector drum.

- Rotate the voltage selector drum until the setting that corresponds to the line voltage in your area faces out, and insert it back into its slot. Do not force the voltage selector drum into the slot; if itis turned upside down it will not fit.
