Primary FIPs:Image Quality Problems
Use Letter–size or A4 paper when troubleshooting an image quality problem.
Image Quality FIPs assume there is no malfunction of the printer controller. Use Printing Test Mode to
determine whether an image quality problem is being caused by the printer engine or by the printer control-
ler. The printer engine 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 you are unable to solve the image problem using the Image Quality FIPs, we recommend that you
replace the printer controller with a known good controller. If the problem still persists, we recommend you
replace each component listed in Initial Analysis of the problem FIP, one by one, until you solve the prob-
lem.
