Top of Form (TOF) Top of Form (TOF) sets the print start position. The factory default is 1" from the top. The TOF can be changed in increments of 1/144", 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. 1 For more information, see “Top of Form (TOF)” in “Using your Printer”. NOTE The Forms Tear-Off and the Top of Form settings interact.
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 “Using your Printer”.
PRINTER DRIVERS EMULATIONS The factory default emulation for your printer is IBM PPR. If you wish to change to one of the Epson or Microline emulations, see “Using your Printer”. PRINTER DRIVERS The Oki driver for your printer is provided on the CD included with the printer. You can either load the Oki driver or select one of the compatible drivers listed below in your software application. 1. Insert the CD into your CD-ROM drive.
WinVer is the Windows versions, and CodePage is the selected option. NOTE To find out more about Code pages, see Help on the Oki CD Browser. 3. After files have finished copying, click [Finish]. 4. Switch your printer ON. USING A COMPATIBLE DRIVER The drivers below are listed by decreasing compatibility with your printer. Use one as close to the top of the list as possible.
privileges are necessary for Windows 2000 and Windows XP installations. This port requires a cable conforming to USB version 1.1 or above. A genuine cable displays the Trident symbol on both connectors. Using an inferior cable can cause printing problems and special cables are needed for longer runs than five metres. The operation of a printer is not assured if a USB compatible device is connected concurrently with other USB compatible machines.
5. The printer will be identified immediately by the New Hardware Wizard and install itself in the Printer folder. An additional item, USB Printing Support will also appear in the Device Manager each time the printer is switched ON and connected. 6. Check that the default paper size has been correctly set by looking at the settings in the Settings > Printers folder. Under the printer's Properties > General tab, the current paper selection is shown.

TROUBLESHOOTING GENERAL INFORMATION Here are some general things to check before proceeding with detailed troubleshooting.
l 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.
Problem 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. 2. Press SHIFT and SEL keys, then press GROUP key. This will print a line showing the emulation you have selected. 3. If you have embedded any printer commands in your software, check to be sure that you entered them correctly. Problem Ink smears on the paper when I print narrow columns.
Problem There are dots missing in my printouts. Solution The head gap may not be set correctly. Try moving the headgap lever to a lower setting. If that doesn’t help, the printhead may be damaged; call for service. Problem The ALARM light is flashing. Solution Try turning the printer OFF and then back ON again. If the light still blinks, call for service. Problem The ALARM light is ON and the Character Pitch 10 light is flashing.
Problem 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. Problem The Print Quality and Character Pitch keys on the front panel don't work. Solution The Operator Panel Function in the printer menu can be used to disable these buttons (Limited Function).
