Important Safety Instructions

Your OKI printer has been carefully designed to give you years of safe, reliable performance. As with all electrical equipment, there are a few basic precautions you should take to avoid hurting yourself or damaging the printer:

• Read the setup and operating instructions in this manual carefully. Be sure to save it for future reference.

• Read and follow all warning and instruction labels on the printer itself.

• Unplug the printer before you clean it. Use only a damp cloth; do not use liquid or aerosol cleaners.

• Place your printer on a firm, solid surface. If you put in on something unsteady, it might fall and be damaged; if you place it on a soft surface, such as a rug, sofa, or bed, the vents may be blocked, causing it to overheat.

• To protect your printer from overheating, make sure no openings on the printer are blocked. Do not put the printer on or near a heat source, such as a radiator or heat register. If you put the printer in any kind of enclosure, make sure it is well ventilated.

• The printhead can get quite hot when it has been printing for a length of time. Do not touch the printhead until it has had a chance to cool off.

• Do not use your printer near water, or spill liquid of any kind into it.

• Be certain that your power source matches the rating listed on the back of the printer. If you are not sure, check with your dealer or with your local power company.

• Your printer has a grounded, 3-prong plug as a safety feature, and it will only fit into a grounded outlet. If you can not plug it in, chances are that you have an older, non-grounded outlet; have an electrician replace it with a grounded outlet. Do not use an adapter to defeat the grounding.

• The printer must be installed near a power outlet which remains easily accessible.

• To avoid damaging the power cord, do not put anything on it or place it where it will be walked on. If the cord becomes damaged or frayed, replace it immediately.

E-i

• If you’re using an extension cord or power strip with the printer, make sure that the total of the amperes required by all the equipment on the extension is less than the exten-sion’s rating. Generally, the total ratings of all equipment plugged into any one power line should not exceed 15 amps. Don’t exceed this unless you know that the power line your equipment is plugged into has a rating above 15 amps.

• Aside from the routine maintenance described in this handbook, don’t try to service the printer yourself; opening the cover may expose you to shocks or other hazards. Don’t make any adjustments other than those outlined in the manual — you might cause damage requiring extensive repair work. the Warranty, Regulatory, and Safety Information booklet supplied with your printer explains how to get your printer serviced by qualified Okidata technicians.

• If anything happens that indicates that your printer is not working properly or has been damaged, unplug it imme-diately and follow the procedures in the Warranty, Regulatory, and Safety Information booklet supplied with your printer for having your printer serviced.

Some of the things to look for:

- The power cord or plug is frayed or damaged.

- Liquid has been spilled into the housing, or the

printer has been exposed to water.

- The printer has been dropped or its cabinet has

been damaged.

- The printer doesn’t function normally when

you’re following the operating instructions.

1. Make sure both the printer and the computer are off.

2. Plug the power cord into the back of the printer.

4. Plug the interface cable into the parallel port on the back of the printer, and secure it in place with the wire loops (Ê).

5. Turn the computer back on.

Getting Started E-5

Power Up

Load Paper

Turn the printer on:

• The printhead will cross back and forth along the platen, and the pins will gently fire to determine the printhead gap setting.

• The POWER light will come on.

• The ALARM light will also come on, but don’t be concerned: it’s just telling you that there is no paper loaded.

Your printer has provision for

• Single sheets (top feed)

• Continuous-forms (rear feed) You can also install options:

• Cut Sheet Feeder (top feed) — holds 100 sheets

• Push and/or Pull Tractors for bottom feed of continuous forms, including

– labels – heavy card stock – multi-part forms

See the instructions provided with the options for information on installing them and on loading paper with the option installed.

Your printer’s innovative, “smart” printhead automatically detects and adjusts to the thickness of the paper you’re using, so you don’t have to fuss with setting the printhead gap when you change the type of paper or print path you’re using.

See Appendix A for more details on the types and sizes of print media you can use with your printer.

E-6 Section 1

Loading Rear-Feed Paper

The rear-feed path is recommended for printing reports, etc., on single-thickness, continuous fan-fold paper. For graphics or charts, it’s best to use the single-sheet paper path.

If you have any paper in the paper path, be sure to remove it from the path before installing rear-feed paper!

1. Move the paper lever to the position marked “REAR”.

2. Grasp the front edge of the paper separator (Ê) and pull it up to access the tractors.

3. Pull up on the tractor lock levers (Ë) to release them, then open the tractor covers (Ì).

Getting Started E-7

4. Position the right-hand tractor for the width of the paper you’re loading, then pull the paper through the opening between the printer and the rear cover, and place the first two holes on each side over the tractor pins (Í). Please note that an equal number of paper holes must be engaged on either tractor in order to ensure proper paper feed.

The movement of the left tractor is limited to ensure that the paper will always contact the paper sensor when loaded.

5. Close the tractor covers and adjust the left tractor to position the edge of the paper: reference marks (Î) on the printer indicate the left edge position for the two most common paper sizes.

6. Lock the left tractor in place by pushing back on the lock lever (Ï).

E-8 Section 1

7. Adjust the right tractor so that the paper holes are centered on the pins (careful—if paper is stretched too tight or left too loose, it can jam and cause problems), then lock the right tractor in place by pushing back on the lock lever (Ð).

8. Close the paper separator and flip the wire feed guide over onto the pull-up roller assembly.

9. Push the FF/LOAD button. The paper will automatically feed into the printer and the ALARM light will go out. The printhead moves back and forth, gently firing the pins to sense the paper thickness and set the printhead gap.

10. Check the baseline for the Top of Form (TOF),

indicated by the red line on the clear plastic paper shield (Ñ). If it’s OK, press the SEL button and you’re ready to start printing. If it needs adjustment, set the Top of Form.

The wire feed guide keeps paper from curling back into the printer.

Getting Started E-9

Loading Single-Sheet Paper

The single-sheet path is best for letterhead stationery, memos, and envelopes and is recommended for printing graphs and charts because it provides the most accurate control of the paper.

If you have any continuous-form paper in the

paper path, you must press the PARK button on the front panel to remove it from the path before loading single sheets.

1. Make sure the printer is turned ON and deselected (SEL light off—press SEL button to deselect if necessary).

The ALARM light will remain on until paper is loaded.

2. Move the paper lever to the position marked “TOP”.

3. Grasp the back of the paper separator and unsnap it from the housing, then swing it up into the single-sheet feed position, making sure that the wire feed guide (Ê) is nestled in the separator.

E-10 Section 1

4. Adjust the paper feed guides (Ë) for the width of the paper and drop a sheet of paper into the separator.

5 . Check the baseline for the Top of Form (TOF), indi-

cated by the red line on the clear plastic paper shield (Í).

The paper will automatically feed into the printer, and the printhead will move back and forth, gently firing the pins to sense the paper thickness and set the printhead gap.

If the paper doesn’t feed in properly, the “15” light on the control panel will begin flashing. To correct this, press the SHIFT and RESET buttons simultaneously, then reload the sheet.

If it’s OK, press the SEL button and you’re ready to start printing. If it needs adjustment, set the Top of Form following the instructions on the next page.

Explanation of Menu Items

These explanations are in alphabetical sequence. Line Spacing, Form Tear-Off, Skip Over Perforation, Page Length, and Gap Control appear several times in the menu.

7 or 8 Bit Graphics. Choose graphics your system uses: 7 or 8 (factory default) dots in each column printed.

Auto CR (IBM). If you wish to have the printer automatically add a carriage return when a Line Feed is received at the end of the line, change the setting to Yes.

Auto LF. If your printout is consistently double spaced, select No (factory default); if it overprints, choose Yes.

Auto Feed XT (Epson). If your system uses pin 14 of the parallel interface to control automatic line feed, change the setting to Valid.

Auto Select. With the factory default (No) engaged, the printer will remain deselected after you load in paper so that you can set the Top of Form. If you always use the same Top of Form setting, change this setting to Yes.

Bottom Margin. Change the setting to Invalid if you want printer to ignore the bottom margin setting. Cau-

tion!! This can cause loss of data and damage the printhead.

Character Set. Choose IBM Set I (factory default) or IBM Set II.

Code Page. Choose USA (factory default), Canada French, Multilingual, Portugal, or Norway.

Emulation Mode. Choose IBM PPR (default) for IBM Proprinter III, Epson FX, or ML for Okidata Microline Standard.

Using Your Printer E-29

Form Tear-Off. Choose 500ms, 1 sec, or 2 sec to turn this feature on and select a time interval for the printer to wait before advancing the paper.

Gap Control. Determines how the printhead gap is set. Auto Gap automatically determines paper thickness on first page: for single sheets, it also rechecks each page while printing. Semi Auto Gap is similar; but it does not recheck single sheets while printing. You can also choose a fixed headgap setting of 1 (narrowest) to 9 (widest).

Graphics. Change to bi-directional graphics for faster printing: optimize by the Print Registration setting in the Menu.

I-Prime. Sets what the printer does when it receives the IPrime signal from software. Buffer Print (factory default): prints out buffer contents before resetting. Buffer Clear: dumps buffer contents immediately. Invalid: ignores IPrime signal.

Language Set. Replaces certain symbols with special characters used in the respective foreign language.

Line Spacing. Change from 6 to 8 lpi (lines per inch) to get more lines per page.

Operator Panel Function. Change to Limited Operation to deactivate PRINT QUALITY and CHARACTER PITCH buttons when several people are using the printer and you don’t want these settings changed from the control panel.

This feature also prevents normal access to the Menu. To access the Menu, turn the printer off, then hold down the SEL key while turning the printer on.

Page Length. Selects the length of the paper you’re using. Page Width (Model 521 only). Choose 8” for letter-size

paper. Paper Out Override. Senses when less than one inch of

paper remains and stops printing. Choose Yes to override the detector. Caution!! This can cause loss of data and

damage the printhead.

Pin 18. Sets the signal on pin 18 to +5V (factory default) or Open.

Pitch. Choose character width measured in characters per inch (cpi).

Print DEL Code (MICROLINE Standard). Change to Yes if you wish to print the DEL code (decimal 127) as a solid box.

Print Mode. Choose NLQ Courier or NLQ Gothic font for letter quality printing, utility (factory default) for faster draft printing, or HSD for fastest printing (lowest quality).

E-30 Section 3

Print Registration. Change the setting as required to obtain the best registration for bi-directional printing.

Print Suppress Effective. If you system uses the DC1 and DC3 codes for something other than the print suppress mode, change the setting to No.

Printhead Gap Adjust. Fine tunes the automatic setting of the printhead gap. If your printer is consistently printing too light, change the setting to -1; if it’s too dark, change the setting to +1.

Proportional Spacing. Change the setting to Yes to engage proportional spacing of characters.

Receive Buffer Size. 64K (factory default), 1 Line, or 32K. Selects amount of memory devoted to holding received data. 1 Line will tie up your computer while printing, but if you abort the print job, the printer will stop printing much sooner.

Reset Inhibit. Selecting Yes prevents your software from resetting your printer’s settings.

SI Select Pitch, 10 CPI (IBM only). Sets the pitch (17.1—the factory default— or 15 characters per inch) to be engaged when the printer control panel is set for 10 cpi and the SI command is received.

SI Select Pitch, 12 CPI (IBM only). Sets the pitch (20— the factory default— or 12 characters per inch) to be engaged when the printer control panel is set for 12 cpi and the SI command is received.

Size. Change to Double for double width and height printing.

Skip Over Perforation. Change to Yes if you want the printer to go to the next page when it comes within 1” of the bottom. Keep it set to No if your software has its own page formatting controls.

Style. Change to Italics if you want the printed characters to be slanted.

Time Out Print. If your software spends a long time processing between portions of data it feeds to the printer, change the setting to Invalid to keep your printer from inadvertently dumping the received data while it’s waiting for more.

Wait Time. Sets the amount of time—500 ms, 1 sec (factory default), or 2 sec—the printer will wait for more data before moving to the form tear-off position.

Zero Character. If you don’t wish the printer to use a slash to distinguish the number 0 from the capital letter O, change the setting to Unslashed.

Using the Printer's Features

Tear Feature

When you’re using continuous forms with either the built-in rear-feed tractor or the optional bottom-feed push tractor, you can use this feature to advance the forms up to the tear position so you can easily tear off a printed sheet without wasting paper or readjusting the printer. To do this, simply press the TEAR button on the front panel.

TEAR

SET

The tear feature can NOT be used when the op-

tional pull tractor is installed!

Forms Tear-off Feature

Never engage Forms Tear-off when printing on

labels!

The Forms Tear-off feature automatically moves the paper up to the tear position after the selected interval. When the printer receives data, it will move down to the initial printing position.

This feature is normally turned off. To activate it:

3. Press the SET button (Í) until the time interval you wish to select prints .

4. Hold the SHIFT button (Ê) and press the SEL button (Ë) to exit the Menu mode and save the setting.

Some programs pause occasionally while sending data. If the pause lasts more than the selected interval, the paper will advance to the tear-off position until more data is received. This extra paper movement can cause uneven print registration in graphics. If you have this problem, use the menu to deactivate Forms Tear-Off.

2. Swing the wire guide up into the paper separator, and swing the separator upright.

3. Move the paper lever to “TOP.”

4. Load single sheet paper.

Paper Park Feature

If you have continuous-form paper loaded and you wish to switch to another paper path, first tear off the printed pages, then press the PARK button. The continuous-form paper will immediately retract from the paper path.

PARK

Switching Paper Paths

To switch to single-sheet feed:

1. Tear off any printed pages, then press PARK.

To switch to continuous-form feed:

1. Press FF/LOAD to remove single sheet from paper path if needed.

2. Lower the paper separator and swing the wire guide out.

3. Move the paper lever to “REAR” or “BOT,” as appropriate.

4. Press FF/LOAD.

When you switch paths, the printhead travels and gently fires pins to sense paper thickness and set the gap.

ection 4: Problem Solving

Problem: Nothing happens when I turn on the printer. Solution: The printer may not be plugged in. Check the

power cord connection to the outlet and to your printer. If you’re using a power strip, make sure it’s turned on. Check to be sure that the fuse hasn’t blown or that the circuit breaker hasn’t tripped.

Problem: The printer doesn’t print when the computer sends data.

Solutions: (1) The printer may be deselected. If the SEL light is out, press the SEL button to select the printer.

(2) The printer cable may not be securely connected. Check the cable to be sure that it is properly connected to both the PC and the printer.

(3) If you have installed the serial I/F board, it may not be firmly seated. Check to be sure that the board is firmly seated in the printer.

Problem: I’m getting strange symbols, incorrect fonts, etc., when I try to print a document.

Solution: The printer driver you have engaged does not agree with the emulation selected for your printer.

To check the emulation selected, first make sure paper is loaded, then press the SEL and SHIFT buttons simultaneously to enter the MENU on your printer. Next, press the GROUP button: this will print the emulation selected.

If the emulation is not the one you want to use, press the SET button to change it to the one you want before exiting the MENU (to exit, press SEL and SHIFT buttons).

If the emulation is correct, check your software documentation on how to select a printer driver, then check to be sure that you have selected one of the drivers listed for that emulation in Section 1. The closer the driver is to the top of the list, the more compatible it will be with your printer. If your software doesn’t have any of the indicated drivers available, check with the software manufacturer to see if they have added any additional drivers since you purchased your software.

If you have embedded any printer commands in your software, check to be sure that you entered them correctly.

English-35

Problem: I’ve installed a brand new ribbon and the printing is smeared and streaked.

Solution: The plastic ribbon shield is either loose or missing. The shield must be left on the ribbon when you are installing the cartridge. To remedy this situation, (caution—printhead may be HOT!) move the printhead to the center of the platen and lift off the ribbon cartridge. If the ribbon shield is loose, secure it in place properly. If it’s missing, locate it and reinstall it.

Problem: I see printing on the right side of the page which is lighter or darker than the rest of the print.

Solution: Although the printer automatically sets the head gap, it may sometimes need minor adjustment. To do this:

1. Hold SHIFT button and press SEL button to enter Menu mode.

2. Press GROUP button until Setup group prints.

3. Press ITEM button until Printhead Gap appears.

4. Press SET button to change setting. The default setting is 0. If the printing is sometimes lighter, change the setting to -1; if it’s sometimes darker, change it to +1.

5. Hold SHIFT button and press SEL button to save setting and exit Menu mode.

Problem: The Alarm light is on and the Character Pitch 15 light is flashing.

Solution: This indicates a paper loading error. To stop the flashing light, press the SEL button. Before trying to load paper again, check to be sure that the paper lever is in the correct position (BOT, TOP, REAR) for the path you’re using.

If the paper lever is in the correct position and you’re using rear feed, lift up the paper separator and check to be sure that the paper is properly on the tractors and has not jammed up somehow.

If the paper lever is in the correct position and you’re using the optional bottom-feed push tractor, check the bottom tractor unit to be sure that the paper is properly on the tractors and has not jammed up before entering the printer.

Once the paper is correctly loaded, press and release the SEL button, then hold the SHIFT button and press the RESET (Character Pitch) button.

E-36 Section 4

Problem: The first line is printing too far down on the page and I can’t get it any higher using the SHIFT and LF/Micro Feed Down buttons.

Solution: The setting for the Top of Form (TOF) will be restricted if you have the Forms Tear-Off feature engaged when you set the TOF. To correct for this, you must reset the TOF with the Forms Tear-Off disengaged, as follows:

1. Hold SHIFT button and press SEL button to enter Menu mode.

2. Use GROUP and ITEM buttons to reach Rear Feed Form Tear-Off entry and/or Bottom Feed Form Tear-Off entry, depending on paper path(s) you’re using.

3. Use SET button to change Form Tear-Off setting to Off.

4. Hold SHIFT button and press SEL button to exit Menu mode.

5. Press SEL button to deselect printer.

6. Hold SHIFT button while pressing LF/Micro Shift Down button to set TOF at desired position.

7. Hold SHIFT button and press SEL button to enter Menu mode.

8. Use GROUP and ITEM buttons to reach Rear Feed Form Tear-Off entry and/or Bottom Feed Form Tear-Off.

9. Use SET button to change Form Tear-Off to desired setting (500ms, 1 sec or 2 sec).

10. Hold SHIFT button and press SEL button to exit Menu mode.

Problem: I need to load paper, but the Alarm light is not on and I can’t load paper.

Solution: If the Alarm light is off, the printer thinks it has paper loaded. To correct this problem, press and release the SEL button, then hold the SHIFT button and press the RESET (Character Pitch) button. The Alarm light will come on and you’ll be able to load paper.

Problem: My word processor files don’t print the way I have the MENU and front panel set.

Solution: Before sending a file to the printer, many word processors send either an “initialization string” or an I-Prime signal to the printer.

The initialization string contains codes that reset the printer to a default set of features: otherwise the printer might accidentally print using features set for a previous job. These codes override panel or MENU settings. To set your printer to ignore the reset code, enter the printer MENU (hold SHIFT button while pressing SEL/MENU button) and change the Reset Inhibit item (in the Set-Up group) to Yes. Please note that while this will stop the reset code from resetting your printer, other codes in the

Problem Solving E-37

initialization string may still override the printer MENU and/or front panel settings.

The I-Prime signal is sent over the parallel interface (pin

31) and will automatically override any settings you have made using the front panel buttons. To eliminate this problem, enter the program MENU (hold SHIFT button while pressing SEL/MENU button) and change the IPrime item (in the Parallel I/F group) to Invalid.

Problem: The Print Quality and Character Pitch buttons on the front panel won’t work.

Solution: The Operator Panel Function item on the printer MENU can be used to disable these buttons. If the printer is part of a customized system or if it is used by a number of people, the system manager may have used this option to make sure the printer is always set properly.

Problem: Static electricity causes the paper to stick. Solution: In cold, dry weather, static charges can build

up on continuous-form paper. This can make the paper cling to the paper separator. If you have this problem during high-volume printing jobs, try moving the single sheet paper guides on the separator together so that the paper rests on the guides rather than on the separator itself.

Continuous Forms:

Setting Forms Tear-Off and Top of Form

The Forms Tear-Of f feature automatically advances continuous forms paper to the tear-off position after printing stops.

Top of Form (TOF) is the place on the sheet where the first line of printing begins.

Forms Tear-Off and Top of Form interact. How you go about setting the TOF depends on whether or not Forms Tear-Off is engaged (the def ault is F orms Tear-Off disengaged—OFF).

Important! Do not turn the platen knob (on the right hand side of

the printer). Doing this will always change the TOF setting. If you must use the platen knob to remove paper jams or to move the paper, be sure to

turn the

printer off first. If necessary, the TOF can be reset back to the factory

default by pressing the QUIET/TOF button with paper parked out of the printer, or by turning on the printer while holding the QUIET/TOF and PARK buttons.

Your software may print the first line above or below

the Top of Form setting . If this happens, you must reset the Top of Form according to you software’s needs.

How to Determine the Current Setting for Forms Tear-Off

Before setting the Top of Form you need to verify the Forms Tear-Of f setting.
