Helpful Hints

Your printer has many features and capabilities that will help you:

• save money.

• save time.

• operate the machine.

8 Microline 390/391 Turbo

This section summarizes the features and capabilities directly connected to saving money and time.

Details for these features and capabilities are provided in other sections of this document.

You may want to use some of our Helpful Hints when working with your machine.

Saving Money

Saving Money: Forms Tear-Off

The Forms T ear -Off feature allows a printed page (rear feed, continuous form) to be torn off without wasting paper or adjusting the printer.

Forms Tear-Off automatically moves the paper from the initial printing position (print start position) to the tear-off position, after a time interval (which you select through the menu).

The top of the page (perforation) is even with the tear bar. The tear bar is located under the clear top of the access cover.

Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing (retracts to the initial print position).

When printing stops, the paper will advance to the tear-off position.

This feature is normally turned off. Forms T ear -Of f and the Top of Form settings interact. For more information, refer to “Using Y our Printer, Forms

Tear-Off” and “Using Your Printer, T op of Form.”

User’s Guide: English 9

Saving Time

Saving Time: Internet Support

Oki Data provides support via the Internet. Oki Data’s main web site, www.okidata.com, is the gateway to

Oki Data’s products and services. 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.

You can find information at your convenience, at any time. For more information, refer to “Service and Support, Internet

Support.”

Saving Time: 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, refer to “Using Y our Printer, Paper Park.”

Saving Time: Moving Through the Menu

When the printer is in Menu Mode, you can move forward or backwards through the menu.

T o move forward, press GROUP , ITEM, or Set, whichever is appropriate.

T o move backward, press and hold SHIFT , then GROUP, ITEM, or Set, whichever is appropriate.

For more information, refer to “Using Y our Printer, Menu Mode.”

10 Microline 390/391 Turbo

Operation Tips

Operation Tip: Top of Form

If you turn the platen knob when the printer is turned

on, you will cause the Top of Form to mis-align. Always turn the printer off before turning the platen knob!

Always determine the status of the Forms T ear-Off menu

setting BEFORE setting the T op of Form. Refer to “Using Your Printer, Top of Form, Forms T ear-Off Status (ON or OFF).”

T op of Form sets the print start position for the printer. It is adjustable in increments of 1/144 of an inch. The amount of adjustment is limited to avoid paper jams.

The Top of Form may be left at the factory default (1 inch), changed for a single print job, or set to a new (permanent) default.

The first line prints at the red line of the plastic paper shield (1) on the printhead.

The T op of Form and Forms Tear-Off settings of your printer interact.

How you set the Top of Form depends on the status of the Forms T ear-Off menu setting.

For more information, refer to “Using Y our Printer, T op of Form (TOF).”

32T-18.eps

User’s Guide: English 11

Operation Tip: Turning the Platen Knob

If you turn the platen knob when the printer is turned

on, you will cause the Top of Form to mis-align. Always turn the printer off before turning the platen knob!

Operation Tip: Control Access to the Printer

You can control access to the printer by changing the setting for the Operator Panel Function (in the Menu).

When the Operator Panel Function is set to Full Operation (the factory default), all keys on the front panel operate.

When the Operator Panel Function is set to Limited Operation, 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, refer to “Using Y our Printer, Menu Mode, Menu Settings Table, Setup, Operator Panel Function.”

Installation

Installation Hints

• Read the setup and operating instructions in this document carefully. Be sure to save this document 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. If you place it on a soft surface (such as a rug, sofa, or bed) the vents may be blocked, causing it 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 are not sure, check with your dealer or with your local power company.

20 Microline 390/391 Turbo

• 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, nongrounded outlet. Contact an electrician to have it replaced with a grounded outlet. Do not use an adapter to defeat the grounding.

• 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.

Installation Overview

• 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.

• Protect your printer from overheating. Make sure the openings on the printer are not 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.

To install your new printer, follow the instructions in this section. You must complete these steps for your printer to operate properly.

If you have purchased an accesssory (option) for your printer, refer to the documentation you received with that accessory for installation instructions.

Installation Location

• Place your printer on a firm, solid surface.

• Allow enough space on each side of the machine to easily

access the platen knob and the various paper feed paths.

• Make sure a power outlet is available nearby.

User’s Guide: English 21

Customizing the Installation

Your printer has many settings (defaults) that do not need to be adjusted as part of a standard installation.

However, you may need to adjust settings to fit your standards.

Some settings you may need to adjust as part of your installation are:

• Top of Form (T OF)

• Paper Path

• Printhead Gap

To adjust these settings, refer to the appropriate section in “Using Y our Printer.”

22 Microline 390/391 Turbo

Top of Form (TOF)

If you turn the platen knob when the printer is turned

on, you will cause the Top of Form to mis-align. Always turn the printer off before turning the platen knob! The factory default setting for the T op of Form (where

the printing should begin) is one inch down from the top of the page. Your software may print the first line of print above or

below where TOF is set. You may need to adjust the TOF to meet your software’s needs. Use the procedures in “Using Your Printer, Top of Form, Forms T ear-Off Status (ON or OFF).” The first line prints at the red line of the plastic paper

shield (1) on the printhead.

32t-18.eps

The T op of Form and Forms Tear-Off settings of your printer interact.

How you set the Top of Form depends on the status of the Forms T ear-Off menu setting.

If Forms T ear-Of f is activated (set to ON), set the Top of Form using “Using Your Printer, Setting Top of Form, Forms TearOff ON (Step A).”

If Forms T ear-Of f is NOT activated (set to OFF), set the Top of Form using the “Using Y our Printer , Setting Top of Form, Forms T ear-Off OFF (Step B).”

The Forms Tear-Off feature allows a printed page (continuous forms, rear or bottom feed, with no pull tractor option installed) to be torn off without wasting paper or adjusting the printer.

Forms Tear Off automatically moves the paper from the initial printing position to the tear-off position, after a time interval (which you select through the menu).

The top of the page (perforation) is even with the tear bar. The tear bar is located under the clear top of the access cover.

Paper remains in the tear-off position until the printer receives more data. Then, the paper moves back down for printing (retracts to the initial print position).

When printing stops, the paper advances to the tear-off position.

The default setting for Forms T ear-Of f is OFF . There are two types of Forms T ear-Of f:

• Automatic Forms T ear-Off

• Manual Forms T ear-Off

If the software package you are using “pauses” while

sending data to the printer, Forms Tear-Off may be activated (if it is enabled through the Menu). The pause must be for two or more seconds. No data is lost. Uneven print registration will occur due to the paper movement. If the problem occurs, use the menu to turn off this feature.

Expanded Printhead Gap

Your printer can be used for dedicated bottom-feed printing on extra-thick multi-part forms. Extra-thick multi-part forms range from 0.017-inch (0.43 mm) to a maximum of 0.03 inch (0.79 mm). To print on extra-thick multi-part forms, you engage the expanded printhead gap feature. This expands the head gap settings for extra-thick forms and heavy card stock. It also increases the impact strength of the pins in the printhead.

CAUTION! Once the expanded printhead gap is

engaged, you cannot print on single sheets without changing the gap back. If you try to print on single sheets without adjusting the printhead gap, you can damage the printhead and void your warranty. To disengage the expanded printhead gap, reverse the following steps.

To engage the expanded printhead gap:

1 Turn the printer off. 2 Remove the access cover and the pull-up roller assembly.

Problem 11:

The Print Quality and Character Pitch keys on the front panel don't work.

Problem 12:

Continuous-form paper sticks to the paper separator.

88 Microline 390/391 Turbo

Problem 1:

My word processor files do not print the way I have the menu and front panel set.

Solution:

Always remember that: 1 Settings in your software application will override any

settings in your printer driver.

2 Your printer driver settings will override any settings from

the printer menu or printer front panel.

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 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. Refer to “Using Y our Printer , Menu Mode.”

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. Refer to “Using Y our Printer , Menu Mode.”

User’s Guide: English 89

Problem 2:

Nothing happens when I turn on the printer.

Solution:

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

Problem 3:

The printer does not print when the computer sends data.

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.

Problem 4:

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

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.

90 Microline 390/391 Turbo

Problem 5:

Ink smears on the paper when I print on narrow forms.

Problem 7:

The ALARM light is flashing.

Solution:

This may be caused by excessive printhead travel from the centering position. Enter the Menu and set the Centering Position to MODE 1. Refer to “Using Y our Printer, Menu Mode.”

For the wide-carriage printer, if MODE 1 doesn't work, try setting the Centering Position to MODE 2.

Problem 6:

I've installed a new ribbon and the printing is smeared and streaked.

Solution:

The ribbon shield is either loose or missing. Remove the ribbon cartridge and check the ribbon shield.

If it is loose, secure it. If it is missing, find it and install it.

Solution:

Try turning the printer off and then back on again. If the light still blinks, call for service.

Problem 8:

The ALARM light is on and the Character Pitch 10 light is flashing.

Solution:

This indicates that the paper lever is set at the wrong position for the paper you are trying to use. Move it to the proper setting.

User’s Guide: English 91

Problem 9:

The ALARM light is on and the Character Pitch 15 light is flashing.

Problem 11:

The Print Quality and Character Pitch keys on the front panel don't work.

Solution:

This indicates a paper jam. Press the SEL key and correct the paper jam situation. Refer to “Maintenance, Paper Jams.”

Problem 10:

The printer needs paper, but the ALARM light is not on and I cannot load the paper.

Solution:

Press and release the SEL key. Then, press and hold the SHIFT key and press the RESET

(CHARACTER PITCH) key. The printer is reset.

92 Microline 390/391 Turbo

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.

Refer to “Using Your Printer, Menu Mode.”

Problem 12:

Continuous-form paper sticks to the paper separator.

Solution:

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