Chapter 1 Troubleshooting
Description below assumes that the printer controller is normal. 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
controller with proper one and check for proper operation again.
If the trouble persists even after the replacement, check the host side using the
image troubleshooting for each condition as described below for effective
troubleshooting.
