Important Safety Instructions Y our OKI printer has been carefully designed to give you years of safe, r eliable per- formance. As with all electrical equipment, however , there are a few basic precautions you should take to avoid hurting yourself or damaging the unit: • Read the setup and operation instructions in this manual carefully .
• If you’r e using an extension cord or power strip with the printer , make sure that the total of the amperes r equired 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.

EAN 13 EAN 13 encodes 13 digits and contains the same number of bars as UPC A. The thir- teenth digit combined with the twelfth digit pr ovides a code representing a country .
48 Operation Code 128 Code 128 has 106 dif ferent characters, each of which can have any one of three differ- ent meanings depending on which code set (A, B, or C) is engaged.
ML790/791 Printer Handbook 49 C hapter 4: W orking with Software This chapter covers the fundamentals of setting up commercial software packages for use with your printer . Be sure to r ead your software documentation carefully for more details. Basic T erminology Before we start, let’s examine a few terms with which you may not be familiar .
50 W orking with Software Emulations In order to eliminate hundreds of differ ent sets of printer commands, most printers emulate, or imitate, one of several general printers; i.e., they accept all of that printer ’s commands and behave as though they were the emulated printer .
ML790/791 Printer Handbook 51 Because there are some differ ences in characteristics such as speed or access to vari- ous featur es, you may wish to experiment with several dif ferent drivers.
52 W orking with Software.
ML790/791 Printer Handbook 53 C hapter 5: Problem Solving, Maintenance, & Service This chapter provides solutions to some common printer problems and explains the r outine maintenance procedures that will help keep your printer in tip-top operating condition.
54 Ploblem Solving, Maintenance, & Service …I’m getting strange symbols, incorrect fonts, etc., when I try to print a document? The printer driver you have engaged does not agree with the emulation selected for your printer .
ML790/791 Printer Handbook 55 …there are dots missing in my printouts? The head gap may not be set correctly . T ry moving the head gap lever to a lower setting. If that doesn’t help, the printhead may be damaged; call for service. … the Alarm light is on and the Character Pitch 15 light is flashing? This indicates a paper loading error .
56 Ploblem Solving, Maintenance, & Service …my word processor files don’t print the way I have the MENU and front panel set? Before sending a file to the printer , many word processors send either an “initializa- tion string” or an I-Prime signal to the printer .
ML790/791 Printer Handbook 57 Maintenance This section explains how to change ribbons, clear paper jams and clean your printer . Replacing the Ribbon Cartridge When replacing the ribbon, be sur e to use only ribbons specifically for use with MICROLINE 790 /791 T urbo printers.
