Printing quality problems Condition Black background Toner smear Suggested Solutions 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 47). • 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. 5.
