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.

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.
