Tips for printing on single sheets

There are a few things you should know about printing on single sheets as opposed to continuous paper. When you print on single sheets, you may notice that your printer prints the first page of your file correctly but then prints too low on the next page, or that it prints the last few lines from one page onto the next.

These differences in print position are easy to adjust; you can simply change some of the settings in your application program as described below to get the right results.

1. When you install an application program, it normally asks you what printer you are using. Make sure you choose the correct printer. See

Chapter 1 for the right printer to choose.

2. Many programs include an option to set the maximum lines per page.

If your program has a lines-per-page setting and you are using standard 83 x 11-inch paper, set the lines per page to 61.

Note: To find the right lines-per-page setting for paper that is not St x

11, create a test document using your application program. Set your top and bottom margins to 0 and then create a file of numbered lines from 1 to 66. When you print your file, notice the last number printed on the first page. This is your maximum lines-per-page setting.

3. If your program doesn’t have a lines-per-page setting, try decreasing the top margin or increasing the bottom margin, or both, until you get the results you want.

4. You can also try adjusting the form length setting. For a standard

8 x 11-inch page, try setting the form length at 10 inches.

5. Some programs also let you indicate whether you are using single sheets or continuous paper. Make sure you choose single sheets.

1-4

Setting Up the Printer

Choosing a Place for the Printer

Note:

If you plan to use a printer stand, follow these guidelines: l l l l l

Use a stand that supports at least twice the weight of the printer.

17.8 kg (39.3 lbs) for the IQ-870

24.6 kg (54.2 lbs) for the LQ-1170

Never use a stand that tilts the printer at an angle of more than 15 degrees from horizontal. If you install a cut-sheet feeder, keep your printer absolutely level.

If you position the paper supply below the printer stand, make sure that you allow enough clearance (1.2 inches or

30 mm) between the underside of the stand and the top of the paper supply to keep the paper from catching on the underside of the stand. Also check that the distance between the stand’s supports is at least 280 mm (11 inches), to accommodate any paper size you may use.

Position your printer’s power cord and interface cable so that they do not interfere with paper feeding. If possible, secure the cables to the printer stand.

Align the paper stack with the tractor sprocket units, so that the paper has a straight path into the printer.


Assembling the Printer

After choosing a good place for your printer, you install the ribbon cartridge and paper guide.

Installing the ribbon cartridge

Before installing the ribbon cartridge, make sure that the printer is not plugged into an electrical outlet.

1. Lift the printer cover straight up and off.

Testing the Printer

Before connecting your printer to a computer, use the built-in self-test function to see that the printer is working properly.

Plugging in the printer

1. Make sure the printer is turned off.

2.

Check the label on the back of the printer to make sure the voltage required by the printer matches that of your electrical outlet.

CAUTION:

If the rated voltage and your outlet voltage do not match, contact your dealer for assistance. Do not plug in the power cord.

3. If the power cord is not attached to the printer, connect it to the AC inlet on the printer’s rear panel.

4. Plug the power cord into a properly grounded electrical outlet.

_


Testing the Printer

Running the self test

You can run the self test with either continuous paper or single sheets. Also, you can load paper for the test from the rear, front, top, or bottom. The following steps describe how to run the test on single-sheet paper, loaded from the top. See Chapter 2 for full details on paper handling.

The printer prints the self test in the currently selected font.

1. Make sure that the printer is turned off. Move the paperrelease lever to the single-sheet position.

2.

Hold down the

LF/FF button while you turn on the printer. The printer beeps several times and the

POWER and

PAPER OUT lights come on.

The self test begins by printing on the first and last lines of page

1. The printer then prints the DIP-switch settings and character samples on page 2.



3.

Move the left edge guide until it locks in place next to the arrow guide mark. Then adjust the right edge guide to match the width of your paper.

-

4.

CAUTION:

Run the self test using paper at least 210 mm

(8 i inches) wide for the LQ-870 or 360 mm (14 inches) wide for the LQ-1170; otherwise the print head prints directly onto the platen.

Insert a sheet of paper down between the edge guides until it meets resistance. After about two seconds, the printer loads the paper automatically and starts the self test.

-

-

-.



The self test prints the current DIP-switch settings, followed by font samples for each of the printer’s available fonts.

5. The self test continues until the paper runs out or until you press the

PAUSE button. When the printer beeps, you

can

load another sheet of paper to continue printing font samples.

When you wish to stop the test, press the PAUSE button. To resume the test, press the

PAUSE button again.

6.

Press the

LOAD/EJECT button to eject the paper.

Then turn off the printer to end the self test.

Here is part of a typical self test:

Note: If the self test does not print properly, see Chapter 6.


Connecting the Printer to Your Computer

If the self test printed correctly, you are ready to connect your printer to the computer. Use a shielded twisted-pair parallel cable to connect your computer to your printer’s built-in parallel interface.

Connect the parallel interface cable as described below:

1.

Make sure both the printer and computer are turned off; then plug the cable connector securely into the printer. Squeeze the wire clips together until they lock in place on either side of the connector.

Note: If your cable has a ground wire, attach it to the ground connector beneath the interface connector.

2. Plug the other end of the cable into the computer. (If there is a ground wire at the computer-end of the cable, attach it to the ground connector at the back of the computer.)


Configuring Your Software for the Printer

Most application programs let you specify the type of printer you use so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup section that presents a list of printers.

Choosing from a menu

Although you can use an application program even if it does not list your printer on its printer selection menu, to take full advantage of your printer’s features (including ESC/P 2), choose the LQ-870/1170 or LQ-570/1070 when you set up your program.

If your printer is not listed, call the software manufacturer or call

Epson at (800) 922-8911 to see if an update is available.

Until you receive an update choose from the following list (the printers are listed in the order of preference):

LQ-850/l050

LQ-510/1010

LQ-500

LQ-2550

LQ-2500

LQ-800/1000

LQ-1500

LQ

If none of these printers is listed, select the first one available from the following list: FX, LX, RX, MX, Epson printer, Standard printer,

Draft printer. Because the printers in this list are 9-pin printers, your graphics printing will not be correct.

Paper Handling 2-1

Selecting a Paper Feeding Method

Your printer comes with four paper paths so that you can print on almost any type of paper: l

Choose the top or front paper guide to print on single sheets l

Choose the tractor unit to load continuous paper from the front, rear, or bottom.

You can mount the tractor unit in three different positions to suit your particular needs: use it as a front push-tractor, rear pushtractor, or top pull-tractor.

Once you select a feeding method, you simply set the paperrelease lever, load your paper, and print. You can even print on single sheets without removing your continuous paper supply.

Setting the paper-release lever

You set the paper-release lever to determine the active paper path in your printer. The printer automatically loads paper from the position you choose. The figure below shows which setting to use for single sheets and the various tractor positions.

Paper Handling

Using continuous Paper

Adjusting the top-of-form position

The top-of-form position is the position the printer feeds the paper to when it loads the paper or performs a form feed. This position is important because it determines where the printing begins on the page.

You may need to adjust the top of form to a certain position for printing on ready-made forms. To do this, see Adjusting the loading position on page 3-14.

Removing continuous paper from the pull tractor

1.

Tear off the printed document or excess paper at the tear-off edge.

2. Hold the LF/FF button to feed the continuous paper forward to be ejected.

Note:

When you are printing with the pull tractor, do not use the TEAR OFF and LOAD/EJECT buttons.


Switching Between Continuous and Single Sheets

Even with continuous paper loaded in the printer, you can easily switch to single-sheet printing without removing the continuous paper from the tractor. This feature can be used whenever the tractor unit is installed on the front or the rear or when using both the front and rear (with the optional tractor).

Switching to single sheets

To switch from continuous paper to single sheets, follow the steps below.

1.

If you have a printed document still in the printer, press the

TEAR OFF button to feed the paper forward to the tear-off position.

Tear off the document and press the TEAR OFF button again to feed the continuous paper backward to the loading position.

Paper Handling

Printing on Special Paper

In addition to printing on single sheets and continuous paper, your printer can also print on a wide variety of paper types, such as envelopes, labels, and multi-part forms. Before printing on special types of paper, you may need to change the paper-thickness setting.

CAUTION: When printing on labels or multi-part forms, make sure that your printing stays within the printable area of the page to prevent damage to the print head. For more information on the printable area, see Chapter 7.

Always return the paper-thickness lever to position 0 when you return to printing on ordinary paper.

Setting the paper-thickness lever

To accommodate various thicknesses of paper, the printer is equipped with a paper-thickness lever that can be set to six positions. These positions are identified by the scale on the printer next to the lever.


Printing on Special Paper

Use the following table to set the paper-thickness lever to match the thickness of your paper according to the table below:

Paper type*

Ordinary (single sheets or continuous) 0

Lever position

Ordinary (with film ribbon)

Labels 2

Envelopes 2 to 5

*See Chapter 7 for complete paper specifications

Note: If the paper-thickness lever is set to the second position above, the MULTI-PART light comes on and print speed is reduced.

Multi-part forms

You can use carbonless multi-part forms of up to four parts

(including the original). Make sure you set the paper-thickness lever to the proper position described in the table above.

Except for the paper-thickness setting, you load multi-part paper the same way as ordinary paper. For details, see the sections on loading continuous paper and loading single sheets earlier in this chapter. Pay special attention to setting the top-of-form position.

CAUTION:

Do not load individual multi-part forms from the top. Use the front loading slot instead. Be sure that the multi-part forms do not exceed

0.32 mm (0.0128

inches) in thickness.


-


Labels

When printing labels, always choose the type mounted on a continuous backing sheet with sprocket holes for use with a tractor. Do not try to print labels as single sheets because labels on a shiny backing sheet do not feed properly.

You can load labels from the front (push tractor or pull tractor), or bottom (pull tractor) paper slot; however, for best results you should use the tractor in the pull-tractor position. You load labels the same way that you load continuous paper, except you must also set the paper-thickness lever to 2 before printing labels.

See Loading continuous paper with the pull tractor earlier in this chapter for details.

Never feed labels backward with the LOAD/EJECT or

TEAR OFF buttons. Labels can easily peel off the backing and jam the printer.

Because labels are especially sensitive to extreme temperature and humidity, always use them under normal operating conditions.

Do not leave labels loaded in the printer between jobs; they curl around the platen and may jam when you resume printing.

To remove labels from the paper path after you finish printing, first tear off the labels at a point before the paper slot. Then use the LF/FF button to advance the remaining labels out of the printer.

Paper Handling

2-27


Envelopes

You can load envelopes individually using the single sheet loading feature from the top paper guide only. If you want to load several envelopes at the same time, you can install the optional single-bin cut-sheet feeder. See Chapter 4 for a description of loading envelopes with the cut-sheet feeder.

Before loading an envelope, set the position of the paper-thickness lever to position 2, 3, or 4, depending on the thickness of the envelope. To load an envelope, follow the steps described in loading single sheets from the top, earlier in this chapter.

l

Note:

The print head must not print past the left or right edge of the envelope or other thick paper. Make sure that your application program keeps printing entirely within the printable area of the envelope you are using.

l l

Always keep the longer side of the envelope horizontal.

If you use No. 6 envelopes, make sure the left edge guide is aligned with the arrow on the paper guide.

DIP Switches

DIP-switch functions

This section describes the different features you can control with the printer’s DIP switches.

International character sets

You can choose from eight international character sets by setting

DIP switches l-l, 1-2, 1-3, and 1-4, according to DIP-switch Table

3. See the Appendix for character samples.

The character sets you can select with DIP switches are USA,

France, Germany, United Kingdom, Denmark I, Sweden, Italy, and

Spain I. However, you can also select the following sets only with the ESC R software command: Japan (English), Norway, Denmark

II, Spain II, Latin America, Korea, and Legal.

Character tables

Your printer has five graphics character tables in addition to the italic character table. You can select these character tables by setting DIP switches 1-1, 1-2, 1-3, and 1-4, as listed in Table 4.

To select a graphics character table, you must first turn DIP switch

1-4 on.

Tables of these characters are included in the Appendix.


DIP Switches

Print direction for graphics

The printer ordinarily prints text bidirectionally for speed and prints graphics characters unidirectionally for precise vertical alignment. You can, however, change text printing to unidirectional with the software command ESC U 1.

If you want to increase printing speed, you can change graphics character printing to bidirectional by turning DIP switch 1-5 on. If

DIP switch 1-5 is off, graphics character printing is unidirectional whether or not you use ESC U o.

High-speed draft

By setting DIP switch 1-6 on, you can print at up to 330 cps

(characters per second) if you select the 12 cpi draft font. The printer reduces the number of dots in each draft character to increase the printing speed.

If you select emphasized printing or condensed printing during high-speed draft mode, printing speed temporarily switches to normal draft speed until the enhancement is turned off. Also, if a line contains superscript, subscript, dot-graphics, or downloaded characters, printing speed switches to normal draft speed for that line only.

Input buffer capacity

The input buffer stores data sent from your computer. If you want to free your computer for other tasks while the printer prints, turn

DIP switch 1-7 off to select the 8 KB input buffer.


DIP Switches

Skip-over-perforation

Turning DIP switch 1-8 on when you are using continuous paper enables the skip-over-perforation function. Use this function to leave a one-inch (25.4 mm) space between the last printable line on one page and the first printable line on the next page so that the printer skips over the perforation.

Most application programs take care of the top and bottom margins. Do not turn on skip-over-perforation unless your program does not provide these margins.

You can adjust your top-of-form position with the

MICRO FEED buttons if you want half of the space at the bottom of one page and half at the top of the next page.

Continuous paper page length

When you are printing on continuous paper, DIP switches 2-1 and

2-2 let you select one of the four page lengths described in

DIP-switch Table 5.

Tear off

You can turn DIP switch 2-3 on to select tear-off mode. See page

3-16 for a complete description of using the tear-off mode.

Tear-off mode is available only with continuous paper loaded with the rear or front push-tractor.


DIP Switches

Auto line-feed

When auto line feed is on (DIP switch 2-4 on), the printer follows each carriage-return code (CR) received with a line feed code (LF).

If your printer is double spacing, turn DIP switch 2-3 off. If each line overprints the next, turn DIP switch 2-4 on.


Micro Feed

The micro-feed feature allows you to move the paper forward or backward in 1/180-inch increments. You can use this feature to adjust the loading and tear-off positions.

When you make adjustments to the loading or tear-off positions for continuous paper, the printer remembers the new position even if you turn off the printer. The printer automatically advances paper to the new position when the power is turned on again.

When you adjust the loading position for single-sheet paper, the printer remembers the new position only until you turn off the power. The loading position returns to the factory setting when the power is turned on again.

Using micro feed

To use the micro-feed feature, you press the

ALT button in combination with the

LOAD/EJECT or

LF/FF button, as indicated on the printer’s control panel. Follow the steps below to see how the

MICRO FEED button operates:

1. Make sure that printing has stopped before you adjust the position of the paper.


Micro Feed

2.

While holding down the

ALT button, press the

LOAD/EJECT button to feed the paper forward or press the

LF/FF button to feed the paper backward, as indicated by the arrows above the buttons.

Adjusting the loading position

The loading position is the position of the paper after it is automatically loaded by the printer. If your printing is too high or low on the page, you can change the loading position with the micro-feed feature as follows:

1. Make sure the printer is turned on.

2.

Load either continuous or single-sheet paper (load continuous paper by pressing the

LOAD/EJECT button). The

MULTI-PART light begins to blink.

Note: You

can adjust the loading position only while the

MULTI-

PART light is blinking.


Micro Feed

3. While holding down the


LOAD/EJECT button to move the loading position down on the page, or press the

LF/FF button to move the loading position up on the page.

The printer remembers the new loading position and advances all subsequent pages to the new position.

l

Note:

The printer has a minimum and maximum loading position.

If you try to advance the loading position beyond these limits, the printer beeps and the paper stops moving.

l

When the paper reaches the factory-set loading position, the printer beeps and paper feeding pauses briefly. Use the factory setting as a reference point when adjusting the loading position.


Tear Off

After you finish printing, the tear-off feature advances continuous paper to the tear-off edge of the printer. You can then easily tear off printed sheets. When you resume printing, the printer automatically feeds paper back to the loading position.

This feature lets you save the paper normally lost between documents.

You can use the tear-off feature in either of two ways: l

Turn DIP switch 2-3 on to select tear-off mode.

l

Press the

TEAR OFF button on the control panel.

0 l

CAUTION:

The tear-off feature can be used only with the front or rear push-tractor feeding systems.

l

Never use the tear-off feature with labels. When fed backward, labels may come off the backing and jam the printer.

Using the tear-off mode

When you select tear-off mode with DIP switch 2-3, the printer automatically advances continuous paper to the tear-off position when you finish printing.

The printer advances paper to the tear-off position whenever the printer receives a full page of data or a form feed, and then receives no more data for three seconds.

Enter tear-off mode by performing the following steps:

1. Make sure the printer is turned off. Turn DIP switch 2-3 on.

Also, make sure the page length for continuous paper is selected correctly (DIP switches 2-1 and 2-2).

2. Turn the printer on.


Tear Off

3.

Print on continuous paper loaded on the front or rear tractor

(as described in Chapter 2). When you finish printing, the printer advances the final printed page to the tear-off position.

4. Tear off all printed pages.

Note:

If the perforation does not meet the tear-off edge, you can adjust the tear-off position using the micro-feed feature as described later in this chapter.

5. When you resume printing, the printer automatically feeds the paper back to the loading position and begins printing.

You can leave tear-off mode turned on (DIP switch 2-3 on) even when you are using single sheets or the pull tractor because tear-off mode is disabled when you set the paper-release lever to the single-sheet or pull-tractor position.

Using the TEAR OFF button

Whether or not the printer is in tear-off mode, you can use the

TEAR OFF button to advance continuous paper to the tear-off position following the steps below:

1.

Make sure printing has finished. Press the

TEAR OFF button.

The printer advances the paper to the tear-off edge and the

TEAR OFF light comes on.

2. Tear off all printed pages.

Note:

If the perforation does not meet the tear-off edge, you can adjust the tear-off position using the micro-feed feature as described in the next section of this chapter.

3. When you resume printing, the printer automatically feeds the paper back to the loading position and begins printing. (You can also manually feed the paper back to the loading position by pressing the

TEAR OFF button again.)

Adjusting the tear-off position

If the paper’s perforation does not meet the tear-off edge, follow the steps below to adjust the tear-off position:

1. Make sure the paper is in the tear-off position and the

TEAR

OFF light is on.

2. While holding down the


LOAD/EJECT button to move the tear-off position down on the page, or press the

LF/FF button to move the tear-off position up on the page. The printer remembers the new tear-off position even after the printer is turned off.

3. Tear off any printed pages.

4. When you begin printing, the printer automatically feeds the paper back to the loading position and begins printing.

Note:

l

The printer has a minimum and a maximum tear-off position. If you try to advance the tear-off position beyond the limits, the printer beeps and the paper stops moving.

l

When the paper reaches the factory-set tear-off position, the printer beeps and paper feeding pauses briefly. Use the factory setting as a reference point when you adjust the tear-off position.

Typestyles

You can produce a wide range of typestyles by selecting different character fonts, widths, and other enhancements from the control panel.

The font names on the control panel are meant as guides only; your actual printed results may differ slightly in appearance.

Note:

The settings you select from the control panel remain valid even after you turn off the printer.

Some application programs control all typestyle functions. Because program commands often override panel settings, you should use your application program’s print options instead of the control panel to select typestyles. If your panel setting does not work, check your software user’s manual for instructions on selecting typestyles.

Character fonts

The printer has ten built-in fonts: draft, Courier, Roman, Sans

Serif, Prestige, Script, Script-C, Orator, Orator-S, and OCR-B. To select a font, press the

FONT button until the green indicator light of your desired font comes on. Note that font selection skips over

SLOT unless an optional font module is installed in that slot.

The Roman and

Sans

Serif fonts are scalable. The minimum size of each font is 8 points and the maximum size is 32 points. You can use your application program (if it supports the LQ-870/1170) to increase the size of the font in two-point increments, as shown in the following sample:


Typestyles

Roman

Printer

LQ-870

Single-bin High-capacity

C806371 C806381

LQ-1170 C806391 C806401

The single-bin cut-sheet feeder holds up to 50 single sheets of paper. When this cut-sheet feeder is installed alone, you can still manually insert single sheets using the paper guide.

The high-capacity cut-sheet feeder holds up to 150 sheets of paper.

You can also load up to 25 envelopes automatically with this cut-sheet feeder.

You can also connect both cut-sheet feeders and operate them as a double-bin cut-sheet feeder (see Assembling the double-bin cutsheet feeder). This allows you to load two different types of paper automatically.

Follow the directions included with your cut-sheet feeder to assemble it; then install the cut-sheet feeder as described in this chapter.

Installing a cut-sheet feeder

Installation of each cut-sheet feeder-single-bin, high-capacity, or double-bin-is basically the same. Install your cut-sheet feeder by following the steps below.

1. Make sure the printer is turned off. Remove the paper guide and printer cover.

2.

If the tractor unit is installed in the top-tractor position, remove it and re-install it in the front- or rear-tractor position and install the paper-tension unit.

Note:

Keep the paper guide handy; if you install the single-bin unit, you need to re-install the paper guide after you load paper.

Also, you will need it if you ever remove the cut-sheet feeder.

To remove the interface card, first unplug the power cord; then perform the reverse of the steps above.


Interface Card

The C823051 serial interface card

If you are using an optional interface, it may be necessary for you to alter the communication protocol of the printer or computer so they can communicate properly. In most cases, you should use the information in your optional interface manual or your computer’s manual to match the computer with the interface.

If you are using the

C823051 optional interface card with your printer, make sure that you read through the section below on baud-rate selection. You may also want to refer to the section on handshake timing and error handling for interface information specific to your printer.

For all other data transfer conventions, such as word structure or communications protocol, see the manual supplied with your

C823051 optional interface.

Baud rate selection

You can select from the following baud rates:

150, 300, 600, 1200,

2400, 4800, 9600, and

19,200 bps (bits per second). When you set the baud rate, see the baud rate selection table in the

C823051 interface manual.

Handshake timing

When the vacant area for data in the input buffer drops to

256 bytes, the printer outputs an X-OFF code or sets the DTR flag to

“1” (MARK) indicating that it cannot receive data.

Once the vacant area for data in the buffer increases to

528 bytes, the printer outputs an X-ON code or sets the DTR flag to “0”

(SPACE) indicating that it is again ready to receive data.

Error handling

When a parity error is detected, your printer prints an asterisk (*).

All other errors, including framing and overrun errors, are ignored.

Printing starts too high or too low on the page.

Adjust the top margin set by your application software.

Use Micro-feed to adjust the print position.

l

All the text is printed on the same line.

Set DIP switch 2-4 on so that the printer automatically adds a line-feed code to each carriage return.

a The text is printed with an extra blank line in between.

Two line-feed signals are being sent. Set DIP switch 2-4 off.

l

Troubleshooting

Printing l

Regular gaps occur in the printout.

One-inch skip-over-perforation may be set. Set DIP switch

1-8 off.

l

Skip-over-perforation is set, but the perforation does not fall in the center of the skip.

Adjust the top-of-form position as described in Chapter 2.

Make sure the DIP-switch settings match your required paper length. See page 3-8.

If your application program is setting the top and bottom margins, set DIP switch 1-8 off.

l

Printing starts too low on the page, or the bottom part of one page is printed at the top of the next page.

Be sure to choose the correct printer when you choose a printer from your application program’s menu. See

Chapter 1.

Use your application software to reduce or eliminate the top margin and to reduce the page length.

If possible, specify single-sheet paper with your application software.

If the printer still does not print correctly, try the self test described in Chapter 1. If the self test works properly, the printer is all right and the problem probably lies in the computer, the software, or the cable. If the self test does not work, contact your dealer or a qualified service person.


Paper Handling

The following section guides you through problems in handling single sheets and continuous paper. If you are having problems using the optional cut-sheet feeder, see the section on options starting on page 6-10.

l

Single sheets do not feed properly.

When you insert single-sheet paper, the platen does not rotate and paper does not feed.

Check that the paper-release lever is pushed back to the single-sheet position.

The paper may be too far to the right. Align the left edge guide with the arrow mark on the paper guide.

l l

When you insert the paper, the platen rotates but paper does not feed.

Reinsert the paper more firmly.

Printing starts too low on the page, or the bottom part of one page is printed at the top of the next page.

Be sure to choose the correct printer when you choose a printer from your application program’s menu. See Chapter

1.

If possible, specify single-sheet paper with your application software.

Use your application software to reduce or eliminate the top margin and reduce the page length.

Reduce the lines-per-page setting in your software.


Paper Handling

9 The paper feed is crooked or the paper jams.

Turn off the printer and put the paper-release lever in the pull-tractor position. Pull out the paper and check the following two items: l l

When you use the cut-sheet feeder, the paper does not feed properly.

l

When a print command is sent from the computer, the platen rotates but paper does not feed.

l

The cut-sheet feeder may be incorrectly installed on the printer.

See that the paper-release lever is pushed back to the single-sheet position.

Paper may be jammed near the print head.

You may have loaded too many sheets in the cut-sheet feeder’s bin.

There may be only one sheet left in the bin. Add more paper.

Two or more sheets feed at the same time.

You may have loaded too many sheets in the cut-sheet feeder’s bin.

You may have forgotten to fan the stack of paper before loading it into the bin. Remove the paper and fan it.

l

The paper feed is crooked.

The paper may be old or creased. Use only new, clean sheets of paper.

There may be too much paper in the stacker.

Make sure that your paper is the proper size and quality.

Optional Specifications

Initialization

There are three ways that the printer can be initialized (returned to a fixed set of conditions):

Hardware initialization

When the power is turned on or when the printer receives an INIT signal from the parallel interface (pin

31 goes LOW).

Software initialization

Panel initialization

When software sends the ESC @ (initialize the printer) command.

When the

PAUSE

button is pushed with the

ALT

button held down.

These three kinds of initialization have slightly different effects.

Software and panel initialization do not initialize the printer mechanism or clear the user-defined character set. Also, software initialization does not clear the data buffer of all text.

A-6 Appendix

Glossary

The following definitions apply specifically to printers.

application program

A software program that helps you carry out a particular task, such as word processing or financial planning.

ASCII

American Standard Code for Information Interchange. A standardized coding system for assigning numerical codes to letters and symbols.

auto line feed

When this feature is selected using a DIP switch, each carriagereturn code (CR) is automatically followed by a line-feed (LF) code.

bidirectional printing

Printing in which the print head prints from left to right only on every other line. On the other lines, it prints from right to left.

This increases the speed of printing because the head prints in both directions.

bit

A binary digit (0 or 1), which is the smallest unit of information used by a printer or computer.

byte

A unit of information consisting of eight bits.

character set

A collection of letters, numbers, and symbols.

Glossary GL-1

character table

A portion of the printer’s standard ASCII character set that you use for graphic symbols or italic characters.

characters per inch (cpi)

A measure of the size of text characters. Ten cpi is the printer’s default setting.

condensed printing

Printing in which each character is approximately 60% of the width of standard characters. Useful for fitting wide tables or spreadsheets onto a page.

continuous paper

Paper that has sprocket-feed holes on each side, is perforated between pages, and is supplied in a folded stack. Also called fanfold paper.

control code

Special codes used to control printer functions such as performing a carriage return or line feed.

cpi

See characters per inch.

cut-sheet feeder (CSF)

An optional, detachable device that automatically feeds single sheets of paper into the printer.

data dump

A troubleshooting feature that helps advanced users find the cause of communication problems between the printer and the computer.

When the printer is in data dump mode, it prints each code it receives in hexadecimal notation and ASCII code. Also called hex dump.

GL-2 Glossary

default

A value or setting that takes effect when the equipment is turned on, reset, or initialized.

DIP switches

Small switches in a printer that control various printer functions and set the default status of the printer when it is turned on or initialized. DIP stands for dual in-line package.

dot matrix

A method of printing in which each letter or symbol is formed by a pattern (matrix) of individual dots.

double-height printing

Printing in which each character is twice as tall as normal.

double-strike printing

A way of producing bolder characters. Each character is printed twice.

double-width printing

Printing in which each character is twice as wide as normal.

draft

One of three print qualities available on your printer.

Draft uses a minimum number of dots per character for high-speed printing. See also high-speed draft and Letter Quality.

emphasized printing

A way of producing darker characters. Each character is printed twice, with the second slightly to the right of the first.

ESC/P

Abbreviation for Epson Standard Code for Printers. This system of commands gives you software control of your printer from your computer. It is standard for all Epson printers and supported by most application software for personal computers.

Glossary

GL-3

ESC/P 2

The enhanced version of the ESC/P printer command language.

Commands in this language give laser-like features: scalable fonts and enhanced graphics printing.

font

A font is a style of type designated by a family name.

form

feed

A control code and a panel button that advance the paper to the next top of form position.

high-speed draft

One of the three print qualities available on your printer.

High-speed draft uses a minimum number of dots per character to produce extremely high-speed printing. See also draft and Letter

Quality.

initialize

To establish the initial default status of the printer by turning on the printer or sending an INIT signal.

interface

The connection between the computer and the printer. A parallel interface transmits data one character or code at a time, and a serial interface transmits data one bit at a time.

italics

A typestyle in which the characters slant. This sentence is italicized. Also, a character table that contains italicized characters and symbols.

Letter Quality (LQ)

One of three print qualities available on your printer. Letter

Quality provides better readability and appearance at a reduced print speed. See also draft and high-speed draft.

-

._

GL-4 Glossary

line feed

A control code and a panel button that advance the paper one line space.

loading position

The position to which the paper is automatically loaded. It can be adjusted with the micro-feed feature.

micro feed

A feature that adjusts the paper loading and tear-off positions.

parallel interface

See interface.

platen

The black roller that provides a backing for the paper during printing.

proportional printing

Printing in which the width of the character varies from character to character. For example, a capital W receives much more space than a lower case i. The result looks more like a typeset book than a typewritten draft.

RAM

Random Access Memory. The portion of the printer’s memory used as a buffer and for storing user-defined characters. All data stored in RAM is lost when the printer is turned off.

reset

To return a printer to its defaults by sending a command or an

INIT signal or by turning the printer off and then back on.

self test

A method for checking the operation of the printer. When the self test is run, the printer prints out its current DIP switch settings and the characters that are stored in its ROM.

Glossary GL-5

subscript

Printing in which each character is printed at about two-thirds the normal height in the lower part of the character space.

superscript

Printing in which each character is printed at about two-thirds the normal height in the upper part of the character space.

tear off

A feature that automatically feeds the perforation of continuous paper to the tear-off position and then feeds the paper back to the loading position.

tear-off position

The position the printer feeds the paper to when you press the

TEAR OFF

button or when the auto tear-off mode is on. This position can be adjusted using micro-feed so that the paper’s perforation meets the printer’s tear-off edge.

top of form

The position on the paper that the printer recognizes as the first printable line. The printer feeds the paper to this position when it loads the paper.

unidirectional printing

Printing in one direction only. Unidirectional printing is useful for printing graphics because it allows more precise vertical alignment than bidirectional printing.

user-defined characters

Characters that are defined and stored in the printer by the user.

Also known as download characters.
