Safety
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:
• Carefully read all setup and operating instructions. Be sure to save all documents for future reference.
• Read and follow all warning and instruction labels on the printer itself.
• Place your printer on a firm, solid surface. If you put in on something unsteady, it might fall and be damaged.
• Avoid overheating the printer. Do not place it on a soft surface, such as a rug, sofa, or bed. The vents may be blocked, causing the printer to overheat.
• The printer must be installed near a power outlet which will remain easily accessible.
• Be certain that your power source matches the rating listed on the back of the printer. If you aren’t sure, check with your dealer or with your local power company.
• Your printer has a grounded, 3-prong plug as a safety feature. 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. 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, 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.
• 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.
3
• Unplug the printer before you clean it. Use only a damp cloth. Do not use liquid or aerosol cleaners.
• 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. Do not spill liquid of any kind into it.
• Do not poke anything into the ventilation slots on the sides of the printer. You could get a shock or cause a fire.
• Aside from the routine maintenance described in this document, 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 document. 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. Then, follow the procedures in “Service and Support” for having your printer serviced.
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.

Chapter 2: Helpful Hints
Saving Money: Forms Tear-Off
The Forms Tear-Off feature allows a printed continuous forms page to be torn off without wasting paper or adjusting the printer.
When printing stops, Forms Tear-Off automatically moves the paper to align the perforation with the tear bar (located under the access cover), after a time interval which you select through the menu.
Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing.
Note: This feature is normally turned off.
Important!
Forms Tear-Off and the Top of Form settings interact. For more information, see “Top of Form (TOF) and Forms Tear­Off” in Chapter 3: Using Your Printer.

Paper Park
Your printer’s paper park feature allows you to print a single sheet (cut-sheet) page without removing continuous feed paper from the printer.
For more information, see “Paper Park” in Chapter 3: Using Your Printer.
Operation Tips
Turning the Platen Knob
Top of Form (TOF)
Top of Form (TOF) sets the print start position. The factory default is 1" from the top.
The Top of Form can be changed in increments of 1/180", either for a single print job or set to a new default. The overall amount of adjustment is limited to avoid paper jams.
The first line prints at the red line of the plastic paper shield (1) on the printhead.
For more information, see “Top of Form (TOF)” in Chapter 3.
Important!
Always turn the printer off before turning the platen knob! If you turn the platen knob when the printer is on, the Top of Form misaligns.
Controlling Access to the Printer
You can control access to the printer by changing the setting for the Operator Panel Function in the Menu from Full Operation (the factory default) to Limited Operation.
When Limited Operation is selected, the
CHARACTER PITCH keys don’t work. This prevents these
settings from being changed from the control panel when several people are using the printer.
For more information, see “Changing the Menu Settings” in Chapter 3: Using Your Printer.

Forms Tear-Off Feature
Note: This feature is normally turned off. To use Forms
Tear-Off, you must enter the menu and change the setting to the desired time interval (see next page).
The Forms Tear-Off feature allows a printed continuous forms page to be torn off without wasting paper or adjusting the printer. It can be used for rear feed continuous forms, bottom feed continuous forms (with the optional push tractor installed) or for top feed roll paper (with optional roll paper stand installed).
When the printer is turned on, the paper feeds to the tear-off position.
When data is received, the paper automatically moves down to the print position (TOF) and printing begins.
Note: You can also move the paper down to the print position
manually by pressing
When printing stops, Forms Tear-Off automatically moves the paper to align the perforation with the tear bar (located under the access cover), after the time interval which you selected through the menu.
Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing.

Notes: The status of the Forms Tear-Off menu setting affects
how you set the Top of Form: see “Top of Form (TOF) and Forms Tear-Off” earlier in this chapter.
Do not use Forms Tear-Off with labels or multipart forms!
Forms Tear-Off cannot be used when the optional pull tractor is engaged.
Potential Problems with Software Packages
If Forms Tear-Off is set to On and the software package you are using “pauses” for a long enough interval while sending data to the printer, Forms Tear-Off may be activated. No data is lost, but this causes uneven print registration due to the paper movement.
If this occurs, use the menu to turn off this feature, then use the
TEAR key to move the paper up to the tear position manually
(see next page).

Character Pitch
Important!
Front panel settings for character pitch are normally overridden by software commands.
Character pitch determines how many characters will print on each line. You can choose a specific fixed width for each character of from 10 to 20 characters per inch (CPI). The higher cpi settings are often used for spreadsheets.
In LQ mode, you can select proportional (PROP) which sets character widths based on the character itself: e.g., the letter i is assigned a narrower width than the letter m. This provides a more polished, typeset appearance.
Set the character pitch by pressing (1) until the LED beside the desired setting glows.

Explanations of Menu Items
These explanations are in alphabetical sequence to make it easier to look them up. Some items only appear when optional accessories are installed; others appear in several groups in the menu.
Auto CR, Default =No
IBM Only. If you want the printer to automatically add a carriage return when a Line Feed is received at the end of a line, change the setting to Yes.
Auto LF, Default = No
If your printout is consistently double spaced, select No; if it overprints, select Yes.
Auto Feed XT, Default = Invalid
Epson Only. 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: this item eliminates this potential problem. If your system uses pin 14 of the parallel interface to control automatic line feed, change the setting to Valid.
Auto Select, Default = No
Determines whether or not your printer will automatically be selected after you load in paper. With the factory default engaged, the printer will be deselected so that you can set the Top of Form. If you always use the same Top of Form position, change the setting to Yes.
Bi-direction, Default = Enable
Change this setting if you wish to disable bidirectional transmission (PnP) in Nibble mode.
Bottom Margin, Default = Valid
Change to Invalid if you want the printer to ignore the bottom margin setting.
CAUTION!!
Setting the Bottom Margin to Invalid can cause loss of data and damage the printhead by allowing printing without paper.
Menu Mode 35
Busy Line, Default = SSD-
Appears only when the optional Serial Interface is installed. If Ready/Busy protocol (factory default) is selected, you can choose which line your system monitors for a busy signal:
• SSD -9V, select SSD-
• SSD +9V, select SSD+
• DTR -9V, select DTR
• RTS -9V, select RTS
Busy Time, Default = 200 ms
Appears only when the optional Serial Interface is installed. Sets the length of the busy signal when the Ready/Busy protocol (factory default) is engaged,
Centering Position, Default = DEFAULT
Used to limit printhead travel when printing narrow columns.
• Select Mode 1 for the narrow carriage printer.
• Select Mode 1 or Mode 2 for the wide carriage printer.
Character Set, Default = IBM Set I
Use this to switch character sets to IBM Set II
Code Page, Default = USA
Choose the Code Page character set you wish to use: USA, Canada French, Multilingual, Portugal, Norway, BRASCII, Abicomp, Multilingual 858, or ISO 8859-15.
CSF Bin Select, Default = Bin 1
Appears only when the optional Dual-Bin Cut Sheet Feeder is installed. Use this to switch to Bin 2 as the default.
CSF Type, Default = Wide
To avoid paper jams, change this setting to Narrow if you are using the optional Cut Sheet Feeder on the wide model ML491 printer.
Diagnostic Test, Default = No
Appears only when the optional Serial Interface is installed. Select yes to perform a diagnostic test of the serial interface.
DSR Signal, Default = Valid
Appears only when the optional Serial Interface is installed. Used with the Ready/Busy protocol (factory default) to select the way your system handles the DSR signal.
36 Microline 490/491 User’s Guide
DTR Signal, Default = Ready on Power Up
Appears only when the optional Serial Interface is installed. Change to Ready on Select if the DTR signal is required when the printer is selected (leave as Ready on Power Up if the DTR signal is required when the printer is turned on).
Emulation Mode, Default = Epson LQ
Selects the printer command set (emulation) you want to engage.
Form Tear-Off, Default = Off
Choose 500 ms, 1 sec, or 2 sec to turn the Form Tear-Off feature on and to set the time interval for the printer to wait before advancing the paper.
Graphics, Default = Bi-directional
Change to uni-directional graphics for better registration, but slower printing. With this set for bi-directional, you can optimize the registration using the Print Registration setting in the Menu.
Graphics Speed, Default = Low
Change to High for faster printing when optimum print quality is not an issue.
I-Prime, Default = Buffer Print
Determines what the printer will do when it receives the I-Prime signal from the software.
• Buffer Print: prints out the buffer contents before resetting.
• Buffer Clear: dumps the buffer contents immediately.
• Invalid: causes the printer to ignore the I-Prime command. Select this setting if you wish 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, Default = American
Replaces certain standard symbols with special characters used in foreign languages.
Line Spacing, Default = 6 lpi
Change to 8 lines per inch (lpi) to get more lines on a page.
Menu Mode 37
Operator Panel Function, Default = Full Operation
Change to Limited Operation to deactivate the PRINT QUALITY and CHARACTER PITCH buttons, so that these features can only be controlled through your software. This prevents these from being changed from the control panel when several people are using the printer.
Important!
This feature also prevents access to the Menu. To access the Menu in these circumstances, turn the printer off, then hold down the
Page Length, Default = 11"
SEL
key while turning on the printer.

Page Width, Default = 8"
Wide carriage model only. Change to 13.6" to print on wide paper.
Paper Out Override, Default = No
Senses when less than 1" (25 mm) of paper remains and stops printing. Change to Yes to override the sensor and print closer to the bottom of the page.
Caution!!
Engaging Paper Out Override can cause loss of data and damage the printhead by allowing printing without paper.
Parity, Default = None
Appears only when the optional Serial Interface is installed. Selects the type of parity your system uses: None, Odd or Even.
Page Length Control, Default = by Menu Setting
Change the setting to “by Actual Page Length” if you wish to print on single-sheets longer than 17 inches. When “by Actual Page Length” is selected, the menu setting for Top Feed Page Length is ignored.
38 Microline 490/491 User’s Guide
Pin 18, Default = +5V
Sets the signal on pin 18 to +5 volts or open.
Pitch, Default = 10 cpi
Choose the character width, in characters per inch (cpi).
Power Save Time, Default = 5 min
Sets the interval the printer waits for more data before it goes into the power save mode. Power Saving must be set to enable (the factory default) for this to be effective.
Power Saving, Default = Enable
Change to Disable if you wish to prevent the printer from entering the Power Save mode after the selected interval.
Proportional Spacing, Default = No

Chapter 6: Troubleshooting
General Information
Here are some general things to check before proceeding with detailed troubleshooting.
• Is the printer plugged in and turned on?
• Are the connections (power and interface) secure?
• Is the product being operated under the proper ambient conditions?
• Does the paper being used meet the specifications for this product?
• Is the paper properly installed?
• Is the ribbon properly installed?
• Is an Oki ribbon being used?
• Is the printhead gap correctly set?
• Are the correct printer drivers being used for the printer?
Note: Settings in your software application will normally
override any settings in your printer driver.
Printer driver settings normally override settings from the printer menu or printer front panel.

Problems / Solutions
Problem
My word processor files do not print the way I have the menu and front panel set.
The I-Prime signal will automatically override any front panel settings you have made. To eliminate this problem, enter the Menu Mode, go to the Parallel Interface group and change the setting for I Prime to Invalid.
For more information on changing menu settings, see “Changing the Menu Settings” in Chapter 4.
Solution
Remember:
• Settings in your software application can override settings in your printer driver.
• Your printer driver settings can override any settings from the printer menu or printer front panel.
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 override the panel and menu settings. To change your printer to ignore the reset code, enter the Menu Mode, go to the Set-Up group and change the setting for Reset Inhibit to Yes.

Continuous-form paper sticks to the sheet guide.
Solution
In cold dry weather, static charges can build up and make the paper cling to the sheet guide. Try moving the paper guides together so that the paper rests on the guides rather than on the separator.

Solution
The Operator Panel Function in the printer menu can be used to disable these buttons (Limited Function). 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.
Check with your system manager before changing any menu settings.
