No transfer roller voltage
|
Perform a half-way test and see if there is an image on the imaging drum. If there is an image on the drum, make sure the transfer roller is installed. Without transfer roller voltage, toner cannot be attracted from the surface of the drum to the print media. Replace the transfer roller if necessary.

No developing bias
|
Perform a half-way test and see if there is an image on the imaging drum. If there is no image on the drum, clean the high-voltage power supply contacts. With no developing bias charge, toner is not attracted to the drum. Replace the engine controller board if necessary.

Defective laser scanner cable
|
Perform a half-way test and see if there is an image on the imaging drum. If there is no image on the drum, low-level signals exchanged between the laser/scanner assembly and the engine controller board could theoretically affect laser output. Replace the laser/scanner cable assembly if necessary.
