Troubleshooting Tips
Isolating Controller Board Problems
If you are unable to print a service test page (see "Service Test
Page"), but the printer does cycle through its normal startup
sequence (the fan comes on and the delivery rollers rotate), you
most likely have a problem with the controller assembly or
pickup solenoid.
Refer to the Take Apart chapter for instructions on how to replace
the pickup solenoid and/or controller assembly.
Light Exposure Problems on Test Prints
When the printer cover is removed, the photosensitive drum
inside the toner cartridge may be exposed to light. This exposure
can affect the quality of your printouts.
