Every effort has been made to ensure that the information in this document is complete, accurate, and up-to-date. Oki assumes no responsibility for the results of errors beyond its control. Oki also cannot guarantee that changes in software and equipment made by other manufacturers and referred to in this guide will not affect the applicability of the information in it. Mention of software products manufactured by other companies does not necessarily constitute endorsement by Oki.
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.
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 handbook, do not try to service the printer yourself; opening the cover may expose you to shocks or other hazards. Do not make any adjustments other than those outlined in the handbook, you might cause damage requiring extensive repair work.

Loading Paper Loading Continuous Forms (Rear Feed) We recommend the rear-feed path for printing reports, etc., on single-thickness, continuous-form paper. For graphics or charts, it's best to use the single-sheet path (top feed). Note: If you have paper in the paper path, be sure to remove it before installing rear-feed paper.

Loading Single Sheets (Top Feed) 3. Open the carriage cover and lift the paper separator to the single-sheet position. Use the single-sheet path for letterhead stationery, memos, and individual envelopes. It is recommended for printing graphs and charts because it provides the most accurate control of the paper. Note: If you have continuous-form paper in the path, press the PARK button to remove it before loading single sheets. 1. Make sure the printer is on and deselected (SEL light off).

Troubleshooting Problem: I'm getting strange symbols, incorrect fonts, etc., when I try to print a document. Problem: Nothing happens when I turn on the printer. Solution: (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.) Solution: Check the power cable connection and power outlet to your printer.
Problem: My word processor files don’t print the way I have the menu and front panel set. Solution: This indicates a paper jam. Press the SEL key and correct the paper jam situation ( see “Clearing Paper Jams” earlier in this manual). Solution: Before sending a file to the printer, many word processors send either an “initialisation string” or an I-Prime signal to the printer. The initialisation string contains codes that override the panel and menu settings.
Problem: The Print Quality and Character Pitch keys on the front panel won’t work. Solution: The Operator Panel Function in the printer menu can be used to disable these buttons. If the printer is part of a customised 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: Continuous-form paper is sticking to the paper separator.

System requirements To use your printer through the printer’s built-in USB port, you need the following minimum requirements: Microsoft Windows 98, ME, 2000 or XP, pre-installed on PC equipped with a USB port; a shielded USB interface cable long enough to reach from Series A 4-pin location (computer) to Series B 4-pin (printer), not supplied. Microsoft Windows NT4.0 does not support USB. Administrator privileges are necessary for installation on Windows 2000 and Windows XP.
Connecting the USB Cable Due to the number of possible variants of operating systems it is not possible to describe every combination. Terminology may vary between Windows operating systems and some knowledge is assumed. If you are unsure how to proceed, you should consult your computer documentation or system manager for details. This example uses Windows 2000 Professional. 1. Ensure the printer and computer are easily accessible and turn both units off.
The paper size can be altered by using the drop down arrow and selecting an alternatve size. 8. If the printer had formerly been used as a parallel or serial device and there is no output from the printer once a USB cable has been connected, check to see that the correct port has been selected. This information can also be found in the Properties folder but under the Ports tab. Amend as necessary. 9. If there are printing problems, check to see whether there is a USB connection active in the Control Panel.
Installing the USB driver Note: Installation of the Oki USB driver is only required for Windows 98. You may be called upon for your original Windows 98 CD. Please have this available. 1. After the [Add New Hardware Wizard] window appears, click on [Next]. 3. Insert the printer software CD-ROM disk into drive. Make sure the CD-ROM drive is checked and click on [Next]. After Windows finds the USB driver, click on [Next].
