Operating the Control Panel The indicator lights give you the current status of the printer. The buttons let you control many of the printer settings. Lights POWER (green) On when the power switch is on and power is supplied. READY (green) On when the printer is ready to accept input data. This light flickers during printing. PAPER OUT (red) On when the printer is out of paper or when continuous paper is in the standby position. The printer also beeps when it is out of paper.
Operating the Control Panel FORM FEED When the printer is off line, press this button to eject a single sheet of paper or to advance continuous paper to the top of the next page. LINE FEED When the printer is off line and paper is loaded, press this button to feed the paper one line, or hold it down to feed paper continuously. LOAD/EJECT Use this button to feed the paper to the loading position or to eject paper that is already loaded.
Operating the Control Panel CONDENSED Press this button to select or deselect the condensed mode. The printer beeps once when you select the condensed mode and beeps twice when you deselect it. In the condensed mode all characters are approximately 60% of their normal width. Note: You cannot select the condensed mode while using the Roman or Sans Serif NLQ fonts. Other control panel features The control panel also gives you access to several special functions.
Setting the DIP Switches By changing the settings of the two sets of DIP switches on the right side of the printer, you can control various printer features, such as the character set and page length. These new settings become effective whenever the printer is turned on, reset, or initialized. Changing a DIP switch setting 1. Turn off the printer. 2. Use a pointed instrument, such as the tip of a pen, to turn a switch on or off.
Setting the DIP Switches DIP switch settings The tables below show the settings for each DIP switch function. The current settings appear on your self test printout. See Table 1 See Table 2 characters and DIP Switch 2 ON OFF Invalid Valid 2-1 Short tear-off 2-2 Cut-sheet feeder mode ON OFF 2-3 Skip-over-perforation ON OFF 2-4 Auto line feed ON OFF Table 1 Page length SW1-3 SW1-4 11 inches OFF OFF 12 inches ON OFF 8.5 inches OFF ON 11.
Setting the DIP Switches Table 2 International character set and PC selection DIP switch functions This section describes the different features you can control with the printer’s DIP switches. Character spacing DIP switch 1-1 controls the character spacing. If this switch is off, the printer prints with character spacing of 10 cpi (characters per inch); if it is on, the printer prints with character spacing of 12 cpi. This is 10 cpi printing. ABCDEFGHIJKLabcdefghijkl This is 12 cpi printing.
Setting the DIP Switches Short tear-off When you are finished printing (when the printer receives a full page of data or a form feed and then no more data for three seconds), this feature automatically feeds the perforation of continuous paper to the tear-off edge of the printer cover so that you can tear off the last sheet. When you resume printing, the paper feeds backward to the loading position. To use this feature, set DIP switch 2-1 to off and load continuous paper.
Selecting Typestyles You can produce a wide range of typestyles by combining different character fonts, widths, and other enhancements. You can select typestyles using the SelecType feature on your control panel, the DIP switches, or software commands. Character fonts The printer has three fonts: draft, NLQ Roman, and NLQ Sans Serif. The draft font uses fewer dots per character to allow highspeed printing, which makes it ideal for rough drafts and editing work.
Selecting Typestyles The following samples show the characters for each font. Draft Epson Roman Epson Sans Serif Condensed mode You can use the condensed mode to change the character size. In the condensed mode, characters are approximately 60% of the width of normal characters. You can condense both 10 and 12 cpi in draft mode but not NLQ. To select or cancel condensed mode, press the CONDENSED (LOAD/EJECT) button when the printer is on line. When you select the condensed mode, the printer beeps once.
Selecting an International Character Set International character sets provide you with some characters and symbols used in other languages. The table below shows the eight international character sets you can select with DIP switches 1-6, 1-7, and 1-8 when DIP switch 1-5 is turned off. The table also shows the characters that differ in each set. Note: If you wish to select an international character set when DIP switch 1-5 is turned on, use the ESC R command.
Choosing a Character Table Set DIP switch 1-5 on to select the graphics character tables. Set it off to select the italic character table. The graphics character table depends on the settings of DIP switches 1-6, 1-7, and 1-8. If you have an IBM@ or IBM-compatible computer, select a graphics character set when you wish to print character graphics as they are displayed on the screen. Even if you select a graphics character set, you can still print ordinary text and italics.

If the printer still does not print correctly, contact your dealer or a qualified service person. The print is faint or uneven. • Printed characters have parts missing at the bottom. The ribbon cartridge may not be installed properly. See the section on ribbon installation in Chapter 1.
Printing Printed characters are not what you expected. • The typestyle or characters that are set by your software cannot be printed. Check that the software is correctly installed for your printer. • The font selected by SelecType does not print. Your software may be overriding your SelecType setting. Check the printing style set in your software. • The wrong c har act er s ar e pr i nt ed. The wrong character table or the wrong character set may be selected. Check the settings.
Printing • Regular gaps occur in the printout. One-inch skip-over-perforation may be set. Set DIP switch 2-3 off. Your line-per-page setting in your software may be incorrect. • Skip-over-perforation is set, but the perforation does not fall in the center of the skip. Adjust the loading position. See the section on DIP switches in Chapter 3. Make sure the DIP-switch settings match your required paper length. See the section on DIP switches in Chapter 3.
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 6-10. Single sheets do not feed properly. • Printing starts too low o n t h e p a g e , o r t h e b o t t o m p a r t o f 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.
Paper Handling • The paper feed is crooked or the paper jams. The cut-sheet feeder mode may be turned on. Set DIP switch 2-2 off. Make sure the paper size is within the specified range. See 7-3. • The paper does not fully eject. See that the page-length setting is correct. Continuous paper does not feed properly. • The paper feed is crooked or the paper jams. See that the paper-release lever is pulled forward to the continuous-paper position.
Options This section describes problems you may encounter while using an option with your printer. When you use the cut-sheet feeder, the paper does not feed properly. • When a print command is sent from the computer, the platen rotates but paper does not feed. Make sure DIP switch 1-8 is set on. See the section on DIP switches in Chapter 3. 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.
Options • 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 the paper guides are set correctly and that your paper is the proper size and quality. l One page of printing has spread to two pages. Check that the page-length setting and lines-per-page setting in your software are correct. Switching between the cut-sheet feeder and the push tractor does not work properly.
Options Using the pull tractor with the push tractor, continuous paper does not feed properly. • When you press the FORM FEED or LINE FEED button, the platen does not rotate and paper does not feed. The printer may be on line. Before using the control panel buttons to feed paper, always set the printer off line. • Paper feed is crooked or the paper jams. Something may be obstructing the paper feed. Make sure that the paper can feed smoothly into the printer.
Options • Several lines of space occur in the printout. Skip-over-perforation may be set. Set DIP switch 2-3 to off. • Skip-over-perforation is set but does not work. You may have changed the DIP switches with the power on. To make new DIP switch settings effective, turn the power off, then on again. • Skip-over-perforation is set, but the skip has shifted from the perforation, or the perforation does not fall in the center of the skip.
Options With the roll paper holder, paper does not feed properly. • When you press the LOAD/EJECT button, the platen does not rotate and paper does not feed. You may be trying to feed paper while the printer is on line (ON LINE light is on). Press the ON LINE button once to set the printer off line; then feed the paper. After feeding the paper, press the ON LINE button again to set the printer on line. • When you press the LOAD/EJECT button, the platen rotates but paper does not feed.
Options The paper guide may be in the upright position. Make sure that the paper guide is in the lowered position so that it can act as a paper separator. The paper may be creased. Make sure the leading edge of the roll paper has a clean, straight edge. The roll paper may not meet the specifications for your printer. Be sure to use only paper sizes or weights that are within the specified range. With an optional interface, the printer does not operate properly.

Glossary The following definitions apply specifically to printers. ASCII Contraction of 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 enabled using a DIP switch the printer automatically follows each carriage return code (CR) with a line feed (LF) code. baud rate A measure of the speed of data transmission. Usually expressed in bits per second or bps.
cut sheet feeder (CSF) An optional, detachable advice 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 form. Also called hex dump. default A value or setting that takes effect when the equipment is turned on, reset, or initialized.
emphasized printing A way of producing darker characters. Each character of a line is printed in two passes of the print head; the second time, the dots are printed slightly to the right of the original dots. ESC/P Abbreviation for Epson Standard Code for Printers. The system of commands lets you perform software control of your printer from your computer. It is standard for all Epson printers and supported by most applications software for personal computers.
on line When the printer is on line, it is able to communicate with the computer connected to it. The ON LINE button controls the printer’s on line/off line status. reset To return a printer to its defaults, either by a command, an INIT signal, or by turning the printer off and on. 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.
