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.
4 Microline 490/491 User’s Guide
• 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
Saving Time
The Forms Tear-Off feature allows a printed continuous forms
page to be torn off without wasting paper or adjusting the
printer.
Internet Support
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.
• www.okidata.com is the main web site, the gateway to Oki
Data’s products and services.
• http://my.okidata.com is a powerful area of Oki Data’s web
site designed to help you personalize the information and
service you get from Oki Data.
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.

Oki Data provides support via the Internet:
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
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.
Turning the Platen Knob
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 PRINT QUALITY and
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.
For more information, see “Top of Form (TOF)” in Chapter 3.

4 Reload paper.
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 TEAR.
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).
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.
Using Your Printer 17
Changing the Forms Tear-Off Setting
Manual Forms Tear Off
Note: The default setting for Forms Tear-Off is OFF.

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 CHARACTER PITCH/RESET
(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 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
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.
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-
Code Page, Default = USA
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:

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
36 Microline 490/491 User’s Guide
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.
DTR Signal, Default = Ready on Power Up
I-Prime, Default = Buffer Print
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).
Determines what the printer will do when it receives the
I-Prime signal from the software.
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.
• 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.
Graphics Speed, Default = Low
Change to High for faster printing when optimum print quality
is not an issue.
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 SEL key while turning on the printer.
Page Length, Default = 11"
Selects the length of the paper you are using. This enables the
printer to keep track of the initial printing position (TOF) on
each page.
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
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.
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
Proportional Spacing, Default = No
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.
Change the setting to Yes to engage proportional spacing of
characters.
Protocol, Default = Ready/Busy
Change to Disable if you wish to prevent the printer from
entering the Power Save mode after the selected interval.
Appears only if the optional Serial Interface is installed.
Change to X-ON / X-Off if that is the type of protocol your
system uses.
Print Mode, Default = LQ Courier
Receive Buffer Size, Default = 64K
Choose the quality and typeface of printing.
Print Registration, Default = 0

IBM emulation only. Sets the pitch to be engaged when the
printer control panel is set for 10 cpi and the SI command is
received.
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 dumping the received data
while it is waiting for more.
SI Select Pitch 12 cpi, Default = 20 cpi
IBM emulation only. Sets the pitch to be engaged when the
printer control panel is set for 12 cpi and the SI command is

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.
59
Problems / Solutions
Problem
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.
My word processor files do not print the way I have the menu
and front panel set.
For more information on changing menu settings, see
“Changing the Menu Settings” in Chapter 4.
Solution
Remember:
Problem
• 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.

tripped.
Problem
Problem
The printer does not print when the computer sends data.
I'm getting strange symbols, incorrect fonts, etc., when I try to
print a document.
Solutions
1 Is the SEL light on? If not, press the SEL key.
2 Check that the interface cable is securely connected to both
the printer and the computer.
3 If you have the optional serial interface board installed,
check to be sure that it is firmly seated in the printer.
Solutions
1 Check to be sure that the printer driver you have selected in
your software matches the printer emulation.
• Press SHIFT and SEL keys, then press GROUP key.
• This will print a line showing the emulation you have
selected.
2 If you have embedded any printer commands in your
software, check to be sure that you entered them correctly.
Troubleshooting 61
Problem
Problem
Ink smears on the paper when I print narrow columns.
I've installed a new ribbon and the printing is smeared and
streaked.
Solution
This may be caused by excessive printhead travel from the
centering position. Enter the Menu and set the Centering
Position to MODE 1. See “Using Your Printer, Menu Mode.”
Solution
The ribbon shield (1) is either loose or missing.
For the wide-carriage printer, if MODE 1 doesn't work, try
setting the Centering Position to MODE 2.
Remove the ribbon cartridge and check the ribbon shield.
• If it is loose, secure it.
• If it is missing, find it and install it.

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
Check with your system manager before changing any menu
settings.
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.
