Print Image Quality Problems
The toner cartridge may not be seated correctly. Through use and vibration the toner car-
tridge may have disconnected from the electrical contacts inside the printer. Reinstalling the
toner cartridge should reestablish a good electrical connection.
2. Disconnect then reconnect the interface cable that runs between the printer and the host
computer.
There could be a bad connection between the printer and the computer. Reconnecting both
ends should reestablish a good electrical connection. If you have another interface cable avail-
able, substitute that cable for the one currently connecting the printer and the computer.
3. Reinstall the appropriate print driver software located in the DRIVERS folder on the Elec-
tronic Library CD-ROM.
The print driver software running on the host computer may be corrupted. Reinstalling the
software is an easy and inexpensive way to isolate or eliminate the cause of the problem.
4. Replace all of the paper in the paper trays with newly opened paper.
The paper in the trays may be damp or damaged, resulting in poor image transfer. New paper
may correct the problem.
5. Replace the toner cartridge with a new one.
The toner cartridge may be damaged.
6. Call your service technician.
This image quality problem may be caused by a malfunctioning or broken component that
requires service.
Image is extremely dark and/or white areas are not clean
The following characteristics define this print image problem:
• The print is very dark.
• Black image areas are too black, with little or no detail in them.
• There is little or no separation between individual letters and
words.
• White areas on the page may have a light gray cast to them.
• The control panel does not display an error code.
The following procedure guides you through multiple actions that
may solve this print image quality problem. Proceed one step at a time
until the problem is solved—you may not need to complete the entire
procedure. If one of the steps in this procedure corrects the problem
but the identical problem returns in less than 50 prints, call for service.
1. If your printer and software allows you to change the image density setting, adjust the setting
to the midpoint and print 20 pages of dense text or graphics.
If your system has an image density adjustment and it is set to maximum darkness, unused
toner may build up in the printer developer system and cause dark and dirty prints.
2. If your printer and software does not have an image density adjustment, attempt to decrease
the amount of toner in the printer developer system by running 20 pages of dense text or
graphics. Do not run a solid black page.
