Important Safety Instructions

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

• Read the setup and operation 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 it 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. Don’t 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.

• Do not put anything into the ventilation slots on the sides of printer, you could get a shock or cause a fire.

• The printhead can get quite hot when it has been printing for a length of time. Do not touch the printhead untill 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’re not sure, check with your dealer or with your local power company.

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

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

• 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 extension’s rating. Generally, the total ratings of all equipment plugged into any one power line should not exceed 15 amperes. Don’t exceed this unless you know that the power line your equipment is plugged into has a rating above 15 amperes.

• 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.

• If anything happens that indicates that your printer is not working properly or has been damaged, unplug it immediately and follow the procedures in Chapter 5. These are 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.

8 Installation

hapter 2: Loading Paper

Your printer has provision for single-sheet paper feed from the top and for continuous-form paper feed from the rear. Y ou can also install options: the Cut Sheet Feeder, which holds a stack of 100 sheets for feeding from the top and the Push and/or Pull Tractors for feeding continuous-form labels, heavy card stock or multi-part forms from the bottom. See Chapter 5 for more information on these options.

Top Feed

• Single sheets (basis weight 14 to 24 lbs)

• Single envelopes – 24-lb maximum – 6.5” to 9.5” wide

• Transparencies (8.5 x 11”)

Rear feed (continuous forms only, thickness to 0.014” [0.36 mm])

• Single-part continuous forms – 12 to 24 lb. – Minimum 3” wide

• Carbonless, multi-part forms – Original, plus 3 copies – 9 to 11 lb – Minimum 3” wide

• Interleaf, multi-part forms (with carbon paper) – Original, plus 3 copies – 10 to 12 lb paper, with 9 lb carbon – Minimum 3” wide

ML390/391 Turbo Printer Handbook 9

Bottom feed (continuous forms only, thickness to 0.017” [0.44mm])

Paper Handling

Your printer has several handy paper handling features:

• Tear

• Form Tear-off

• Paper Park

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.

Forms T ear-off Feature

Caution!

Do not engage Forms Tear-off when printing on labels!

The Forms Tear-off feature can be engaged to automatically move the paper up to the tear position after the selected interval (500 milliseconds, one second, or two seconds). The page will stay in the tear-off position until the printer receives data. It will then move down to the initial printing position.

This feature is normally turned off. To activate it, enter the printer menu (see Menu Mode in Chapter3) and choose one of the intervals.

Some programs, such as high resolution graphics packages, pause occasionally while sending data to the printer. If the pause lasts mor e than the selected interval, the paper will advance to the rear-off position until more data is received. No data will be lost, but this extra paper movement can cause uneven print registration in graphics. If you have this problem, use the menu to deactivate Forms Tear-off.

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 simply press the PARK button. The continuous-form paper will immediately retract from the paper path.

T esting Your printer

Your printer has three your can run: the Font Test, the Rolling ASCII Test, and the Hexadecimal Dump Test.

Font Test

The Font Test provides a printout containing samples of available typefaces. Here’s a portion of a Font Test printout:

ML390/391 Turbo Printer Handbook 39

To run the Font Test:

1. Be sure paper is loaded.

2. Turn off printer.

3. Hold LF button for several seconds while turning printer on. (IF printer simply

turns on without starting to print, you didn’t hold down LF button long enough.)

Rolling ASCII Test

The Rolling ASCII Test produces a continuous printout of all ASCII characters. The printing will continue until you stop it manually by pressing the SEL button. Here’s a sample portion of a Rolling ASCII Test:

40 Operation

To activate the Rolling ASCII Test:

1. Be sure paper is loaded.

Caution!

2. Turn off printer.

3. Hold QUIET button for several seconds while turning printer on. (If printer sim-

ply turns on without starting to print, you didn’t hold down QUIET button long enough.)

Hexadecimal Dump Test

If you want to test the data your computer is sending to the printer , you can place the printer in the Hexadecimal Dump Mode. When the printer is in the Hex Dump Mode, all data received, including text and printer commands, will be printed in both hexadecimal and ASCII format.

For example, this line of BASIC code:

LPRINT CHR$ (27);“0”;CHR$ (30);“This is an example of a hexadecimal dump.”

For wide carriage Model 391 Turbo, be sure you have wide paper loaded!

In the ASCII format, all non-printable characters will be represented by a period.

would print like this:

ML390/391 Turbo Printer Handbook 41

To engage the Hexadecimal Dump Mode:

1. Be sure paper is loaded.

2. Turn off printer.

3. Hold SEL and FF/LOAD buttons for several seconds while turning on printer.

The printer will print the line “Hex Data Dump” and be ready to receive data in the Hexadecimal Dump Mode. To run the test, simply send data to the printer while it is in the Hexadecimal Dump Mode.

When you’re done, you can exit the Hexadecimal Dump Mode by either pressing the SEL button or by turning the printer off, then on again.

Resetting T op of Form

To reset the Top of Form to the factory default:

1. Turn off printer.

2. Hold down QUIET and PARK buttons while turning printer back on.

Using Bar codes

Your MICROLINE 390/391 Turbo printer incorporates eight different bar codes:

• UPC A

• UPC E

• EAN 8

• EAN 13

• Code 39

• Code 128

• Interleaved 2 of 5

• Postnet

42 Operation

You will find a list of the bar code printer commands for each emulation in appendix C.

Here is a brief explanation of each of the available bar codes, along with a sample printout for each one.

UPC A Bar Code

UPC (Universal Product Code) bar coding is used in the supermarket industry. UPC A coding contains ten digits: the first five digits represent the manufacturer, the second five digits identify the product.

UPC E

UPC E bar coding is a six-digit variation of UPC A, used for labeling small items.

ML390/391 Turbo Printer Handbook 43

EAN 8

EAN (European Article Numbering) bar coding is a variation of UPC coding. EAN 8 encodes eight digits.

EAN 13

EAN 13 encodes 13 digits and contains the same number of bars as UPC A. The thirteenth digit combined with the twelfth digit provides a code representing a country.

Code 39

Also known as 3 of 9 Code, code 39 is used in non-retail applications. Each character has five bars and four spaces. Code patterns have been developed for 44 different alphabetic, numeric and graphic characters.

44 Operation

Code 128

Code 128 has 106 different characters, each of which can have any one of three dif fer ent meanings depending on which code set (A, B, or C) is engaged. A special code at the beginning indicates which set is engaged: three shift codes are also available for use within the bar code to indicate a change in the code set engaged, as required.

Interleaved2 of 5

Inerleaved2 of 5 bar coding is used mainly in the distribution industry. Two digits are encoded: one in the bars and one in the spaces.

Postnet

Postnet bar coding is used by the U.S. Post Office for sorting mail by automated equipment. It incorporates a coding system using five bars and four spaces for each digit.

hapter 4: W orking with Software

This chapter covers the fundamentals of setting up commercial software packages for use with your printer . Be sure to read your software documentation car efully for more details.

Basic T erminology

Before we start, let’s examine a few terms with which you may not be familiar.

Printer Commands

If you’re using commercial software with an appropriate printer driver (see “Printer Drivers” below), the printer commands will normally be sent to the printer by your software and you won’t even need to think about them.

Printer commands are signals sent by your PC to the printer which guide and control its operation. Printer commands tell the printer what character pitch to use, what font to use, what margins to use, whether to use single or double spacing, when to engage/disengage double width or double height printing, etc.

Printer commands can be sent in decimal, ASCII, or hexadecimal form. The values (decimal/ASCII/hexadecimal) for each type of command depend on which emulation is active (see Appendix C for a listing of printer commands for each emulation).

With only a few exceptions, printer commands begin with the ESC character, decimal 27 (hexadecimal 1B), which serves as signal to the printer that what follows is to be interpreted as a command rather than just a string of characters. Some printer commands expect you supply a numerical value, representing tab stops, line spacing, etc.

ML390/391 Turbo Printer Handbook 47

Emulations

In order to eliminate hundreds of different sets of printer commands, most printers emulate, or imitate, one of several general printers; i.e., they accept all of that printer’s commands and behave as though they were the emulated printer.

Your printer has three emulations:

• IBM Proprinter

• IBM AGM

• Epson LQ (factory default)

Printer Drivers

Most of the time, your printer will be controlled by standard commercial software packages such as Lotus

Commercial software packages use printer drivers to control the appearance of printed documents. A driver is simply a list of printer commands tailor-made to cause the printer to perform various functions at the request of the software, producing documents with the correct format. The availability of different drivers makes it possible for a program to function roughly the same way no matter which printer is being used, so long as you select the correct driver for the printer you’re using. If you don’t select the correct driver , you’ll get strange symbols, incorr ect fonts, etc., being printed instead of a great-looking document!

1-2-3®, WordPerfect®, and Microsoft® Windows.

When you use your printer with a software package, you need to select a driver compatible with your printer in order to have the software send the people printer commands to instruct your printer as to how to format and print the document.

A Printer Driver Diskette is not included in your package. If you have any questions or need further information about Printer Driver , please contact the dealer where you purchased your printer.

48 Working with Software

Compatible Printer Drivers

Many of the software packages you use will contain drivers 100% compatible with your printer. For older software, however, it may be necessary to select a driver that functions nearly the same as a driver specifically designed for your printer. This generally means that you will be selecting a driver that provides commands to access most, but not all of the available functions; however , the commands that are available will perform properly with your printer.

The table below summarizes the various drivers that will work with your printer. They are listed in order by decreasing compatibility as you go down the list: select one from as high up on the list as possible, based on what is available from among the drivers supplied with your software. If you don’t see one from near the top of the list, give the software manufacturer a call to see if they have added any drivers to those supplied when you purchased your software. Softwar e manufacturers ar e constantly updating their lists of drivers to keep up with the printer market and they may very well have one which will give maximum compatibility with your printer.

Epson LQ Emulation

Because there are some differences in characteristics such as speed or access to various features, you may wish to experiment with several differ ent drivers. If you must select a driver that is not listed in the table, be sure to check it thoroughly for print features such as boldface, underline and changes in pitch. Don’t be surprised if boldfaced items are printed twice, underlines are misplaced, wide spaces are left between lines or the printer behaves chaotically (turn off the printer if the latter occurs). These are all characteristics of an incompatible driver selection.

hapter 5: Ploblem Solving,

Maintenance, & Service

This chapter provides solutions to some common printer problems and explains the routine maintenance procedur es that will help keep your printer in tip-top operating condition. It also tells you how to order parts, consumables and accessories, and provides information on obtaining service for your printer. You will find your printer’s warranty at the back of this Printer Handbook.

Problem Solving

What if …

…nothing happens when I turn on the printer?

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.

…the printer doesn’t print when the computer sends data?

The printer may be deselected. If the SEL light is out, press the SEL button to select the printer .

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.

If you have installed the serial I/F board, check to be sure that the board is firmly seated in the printer.

ML390/391 Turbo Printer Handbook 51

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

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 on page 49). 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 sur e that you entered them correctly.

…I’ve installed a brand new ribbon and the printing is smeared and streaked?

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

…there are dots missing in my printouts?

The head gap may not be set correctly. Try moving the head gap lever to a lower setting. If that doesn’t help, the printhead may be damaged; call for service.

52 Ploblem Solving, Maintenance, & Service

… the Alarm light is on and the Character Pitch 15 light is flashing?

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

Caution!

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 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 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.

…I need to load paper, but the Alarm light is not on?

If the Alarm light is of f, the printer thinks it has paper loaded. T o correct this pr oblem, 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.

…my word processor files don’t print the way I have the MENU and front panel set?

Always turn the printer off before you turn the platen knob!

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 storing contains codes that reset the printer to a default set of features: otherwise the printer might accidentally print using features set for a pr evious job. These codes will 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 initialization string may still override the printer MENU and/ or front panel settings.

ML390/391 Turbo Printer Handbook 53

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 I-Prime item (in the Parallel I/F group) to Invalid.

…the Print Quality and Character Pitch buttons on the front panel won’t work?

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.

…static electricity causes the paper to stick?

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 highvolume 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.

Maintenance

This section explains how to change ribbons, clear paper jams and clean your printer .

Replacing the Ribbon Cartridge

When replacing the ribbon, be sure to use only ribbons specifically for use with MICROLINE 390 /391 Turbo printers. For best results,use genuine OKI ribbons.

Explanation of Menu Items

These explanations are in alphabetical sequence to make it easier to look them up. Many of the items will appear only with optional equipment installed, as noted below. You will find the items Line Spacing, Form Tear-Off, Skip Over Perforation and Page Length appearing several times in the menu (once for each paper path).

Auto CR. IBM mode only . No (factory default) or Y es. Choose Y es to make your printer automatically perform a carriage return when a LF is received at the end of the line.

Auto LF. No (factory default) or Yes. Change to Yes if your printer overprints. Keep this set to No if your software adds a line feed when a carriage is received at the end of a line. If your printout is consistently double spaced, set this item to No.

Auto Select. No (factory default) or Yes. Determines whether or not your printer will automatically be selected after you load in paper. With the factory default (No) engaged, the printer will be deselected so that you can set the Top of Form. If you always use the same Top of Form setting, change this setting to Yes so that you don’t have to press the SEL button to select the printer after loading paper.

Auto Feed XT . Epson mode only . Invalid (factory default) or Valid. In the Epson emulation, the XT signal on pin 14 of the parallel interface can control automatic line feed. Some interface cables are wired in such a way that automatic line feed is always in effect: the Auto Feed XT item eliminates this potential problem. The factory setting causes the printer to ignore this signal; if your system uses pin 14 to control automatic line feed, change the setting to Valid.

Baud rate. Appears only if optional Serial Interface is installed. Range from 19,200 to 300 bps: factory setting, 9600 bps. This item sets the transmission rate for the system.

Bottom Margin. V alid (factory default) or Invalid. Sets whether or not the printer will ignore the bottom margin setting. Change the setting to Invalid if you want printer to ignore the bottom margin setting. Be careful if you use this feature: it lets the printer continue printing when there’s no more paper, which can cause loss of data and may damage the printhead.

72 Appendix B: Menu Selections

Busy Line. Appears only if optional Serial Interface is installed. SSD- (factory default), SSD+, DTR, RTS. If Ready / Busy protocol (factory default) is selected, you can choose which line your system monitors for a busy signal:

SSD -9V, select SSDSSD +9V, select SSD+ DTR -9V, select DTR RTS -9V, select RTS

Busy Time. Appears only if optional Serial Interface is installed. 200 ms (factory default) or 1 sec. Sets the length of the busy signal when the Ready / Busy protocol (factory default) is engaged.

Centering Position. Choose centering position.

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

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

Norway BRASCII, Abicomp.

CSF Bin Select. Appears only if optional Dual-Bin Cut Sheet Feeder is installed. Choose Bin 1 (factory default) or Bin 2.

CSF Type. Select Wide (default) or Narrow for CSF type.

Diagnostic Test. Appears only if optional Serial Interface is installed. No (factory de-

fault) or Yes. Select Y es if you want to perform a diagnostic test of the serial interface.

DSR Signal. Applies only when optional Interface is installed. Valid (factory default) or Invalid. Used with Ready / Busy protocol to select the way your system handles the DSR Signal.

DTR Signal. Applies only when optional Serial Interface is installed. Ready on Power Up (factory default) or Ready on Select. Change to Ready on Select if the DTR signal is required when the printer is selected; leave as Ready on Power Up if DTR signal is required when printer is turned on.

Emulation Mode. IBM PPR , IBM AGM, or Epson LQ (factory default). Selects the printer command set you want your printer to use: IBM X24e or XL24e Proprinter, IBM X24e or XL24e Alternate Graphics Mode (AGM), or Epson LQ 850/ 1050.

ML390/391 Turbo Printer Handbook 73

Form Tear-Off. Off (factory default), 500 ms, 1 sec, or 2 sec. Form Tear-Off advances the paper to the perforation so that you can tear off a sheet of continuous-forms paper. You can turn this feature off, or you can select a time interval for the printer to wait before advancing the paper.

Graphics. Uni-directional (factory default) or bi-directional. Bi-directional graphics print faster than uni-directional graphics, but uni-directional graphics have better print registration. Bi-directional graphics printing can be optimized by adjusting the Print Registration setting in the Menu.

Graphics Speed. Low (factory default) or High. Choose High speed for faster printing when optimum print quality is not an issue.

I-Prime. Buffer Print (factory default), Buffer Clear , or Invalid. Determines how the printer will react to the I-Prime signal from your software. With the factory default engaged, when the printer receives the I-Prime signal, it will print out the contents of the buffer before resetting. Change the setting to Buffer Clear if you wish the printer to dump the contents of its buffer immediately upon receiving the I-Prime signal. Change to Invalid if you want the printer to ignore your software’s I-Prime signal. This will permit you to enter settings through the printer’s control panel which will not be automatically overridden by the software’s settings when the I-Prime signal is sent.

Language Set. American (factory default), French, German, British, Danish I, Swedish, Italian, Spanish I, Japanese, Norwegian, Danish II, Spanish II, Latin American, French Canadian, Dutch, or Publisher. Replaces certain symbols with special characters used in the respective foreign languages.

Line Spacing. 6 lpi (factory default) or 8 lpi. Choose 8 lines per inch for tighter line spacing, to get more lines per page.

Operator Panel Function. Full Operation (factory default) or Limited Operation. Change to Limited Operation to deactivate the PRINT QUARITY and CHARACTER PITCH buttons on the control panel. Then you can control these featur es only through your software. This can be useful when several people are using the printer and you don’t want its settings changed.

Important!

Page Length. 11” (factory default), 11 2/3”, 12”, 14”, 17”, 3”, 3.5”, 4”, 5.5”, 6”, 7”, 8”,

8.5”. Selects the length of the paper you’ll be using in your printer. This enables the printer to keep track of the initial printing position on each page (Top of Form).

Page Length Control. Choose page length control system for SASF mode.

by Actual Page Length.....Control page length by actual physical page length.

by Menu Setting................Control page length by logical page length.

Page W idth. Appears in Menu for wide-carriage model only. Choose a page width of

13.6” (factory default) or 8”.

Paper out Override. No (factory default) or Yes. The paper out detector senses when less than an inch of paper remains in the printer and stops printing at that point. Changing this setting to Yes overrides the detector so you can print closer to the bottom of the page if you’re using single sheets. Be careful if you use this feature: it lets the printer continue printing when there’s no more paper, which can cause loss of data and may damage the printhead.

Parity. Appears only if optional Serial Interface is installed. None (factory default), Odd, or Even. Selects the type of parity your system uses.

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

Pitch. 10 cpi (factory default), 12 cpi, 15 cpi, 17.1 cpi, or 20 cpi. Selects the character

width measured in characters per inch (cpi).

Print Mode. LQ Courier (factory default), LQ Roman, LQ Swiss, LQ Swiss Bold, LQ Orator, LQ Gothic, LQ Prestige, or Utility. Choose one of the LQ fonts for letter quality printing; choose utility for high-speed printing.

Print Registration. 0 (factory default), 0.05 mm Left, 0.15 mm Left, 0.20 mm Left, 0.25 mm Left, 0.25 mm Right, 0.20 mm Right, 0.15 mm Right, 0.10 mm Right, or 0.05 mm Right. Change the setting as required to obtain the best registration for bi-directional printing.

Print Suppress Effective. Yes (factory default) or No. Enables/disables print suppress command. The factory default enables the print suppress command: the printer will ignore all data it receives after it accepts the print suppr ess command. Change to No to cause your printer to ignore the print suppress command.

ML390/391 Turbo Printer Handbook 75

Proportional Spacing. No (factory default) or Yes. Change to Yes to engage proportional spacing of characters.

Protocol. Appears only if optional Serial Interface is installed. Selects the type of protocol your system uses: Ready/Busy (factory default) or X-On/X-Off.

Receive Buffer Size. 8K (factory default), 1 Line, or 23K. Selects the amount of memory devoted to holding received data. Choosing 1 Line will tie up your computer during printing, but if you about the print job the printer will stop printing much sooner .

Reset Inhibit. No (factory default) or Yes. Change to Yes if you want your printer to ignore the reset command sent by software. This will prevent your software reset command from changing the settings you have made through the front panel controls or through printer commands. If you engage this feature, don’t for get that it will also prevent your software from clearing out existing settings when you finish printing one document and switch to another.

Serial Data 7/8 Bits. Appears only if optional Serial Interface is installed. 8 Bits (factory default) or 7 Bits. Change to 7 bits if your system uses a 7-bit data format.

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

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

Size. Choose Single (factory default) or Double width and height printing.

Skip Over Perforation. No (factory default) or Yes. Change to Yes if you want the

printer to advance automatically to the next page when it comes within one inch of the bottom of the page. If your software has its own page formatting controls, keep this item set to No to avoid interface.

Style. Choose Normal (factory default) or Italics.

76 Appendix B: Menu Selections

T ime Out Print. V alid (factory default) or Invalid. When printing, if the printer doesn’t receive any data, a line feed, or a form feed signal for awhile, it will automatically dump out what’s in the print buffer. If your software spends a long time prossing between feeding portions of data to the printer, you should change the setting to Invalid to keep your printer from inadvertently dumping the received data while it’s waiting for more.

Wait Tine. 500 ms, 1 sec (factory default), or 2 sec. Sets the amount of the printer will wait for more data before jumping from the print position up to the form tear off position.

Zero Character . Slashed (factory default) or Unslashed. The factory default will cause a slash to appear in zeros to distinguish them from the capital letter O. To disengage the slashed zero, change this to Unslashed.
