Phaser 6121MFP Service Manual

Print-Quality Troubleshooting
Initial Actions for Troubleshooting Print-Quality
Check the Media and Media Settings
Check that the media is clean and dry, and that the media used is supported by
this printer. See “Media and Tray Specifications” on page 1-15.
Verify the media settings are correct at the Control Panel.
Check Printer Condition
Toner
Low toner can cause print-quality problems, such as fading, streaking, White lines,
or dropouts. Print a small document from different software applications to
replicate the problem and check the amount of toner available. If the toner is low,
replace the affected cartridges.
Cleaning
Paper, toner, and dust particles can accumulate inside the printer and cause print-
quality problems such as smearing or specks. Clean the inside of the printer to
reduce these problems. Refer to “Cleaning” on page 7-2.
Calibration
Calibration performs three primary adjustments:
•
Color registration
•
Toner density
•
Toner reproduction curve (used for converting screen colors to CMYK values)
For optimum print quality, the printer automatically performs a calibration cycle
after the following events:
•
A toner cartridge has been replaced.
•
The imaging unit has been replaced.
•
200 pages have printed since the last calibration.
•
A big temperature or humidity change has occurred.
•
The printer is restarted after settings have been changed.
Normally you would not need to perform a calibration routine unless you are
having problems with printing colors.
