3.5 Image Trouble FIP
The descriptions below assumes that the printer controller works normally. By testing
the printing operation for the engine only, conditions can be isolated simply to
determine whether the trouble exists on the printer controller side or engine side.
◆
When the test print with the engine only is correct, the printer controller is fault.
◆
When printing on the engine only is not correct, the engine is faulty.
When trouble is considered to be on the printer controller side, replace the printer con-
troller with proper one and check for proper operation again.
If the trouble persists even after the replacement, check the host side using the image
FIP for each condition as described below for effective troubleshooting.
If print image quality trouble occurs, print on paper of letter or A4 size in order to judge and understand the
trouble precisely and take proper remedy steps. Use the image quality FIP correction table to diagnose the
trouble.
If the problem cannot be corrected according to the image quality FIP, check the trouble after replacing the
"Major check parts" specified for the "Initial check" in the image quality FIP in succession.
