Image Quality Problems
Before troubleshooting an image quality problem, first replace the toner cartridge and test image
quality. If the problem still persists, proceed to the fault isolation procedure.
Use Letter–size or A4 paper when troubleshooting an image quality problem.
Use Printing Test Mode to determine whether an image quality problem is being caused by the
printer or by the printer controller. The printer generates the Test Print. If the test print is normal,
but the regular prints have a image quality problem, the problem may be with the printer
controller.
If the Troubleshooting Tables do not lead you to a solution to your problem, then replace each
part listed in Step 1
