Printing quality problems
129 5. Troubleshooting
Black background If the amount of background shading becomes unacceptable:
• Change to a lighter weight paper.
• Check the environmental conditions: very dry conditions or a high level of humidity (higher than 80% RH) can increase the amount
of background shading.
• Remove the old toner cartridge and install a new one.
• Thoroughly redistribute the toner (see "Redistributing toner" on page 42).
Toner smear • Clean the inside of the machine.
• Check the paper type and quality.
• Remove the toner cartridge and install a new one.
Vertical repetitive defects If marks repeatedly appear on the printed side of the page at even intervals:
• The toner cartridge may be damaged. If you still have the same problem, remove the toner cartridge and, install a new one.
• Parts of the machine may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after
a few more pages.
• The fusing assembly may be damaged. Contact a service representative.
