Question about Office Equipment & Supplies
Try replacing the toner cartridge first, then proceed with the other items.
Thank you and let me know what happens:
DC Controller PCA is defective. If the DC Controller turns on the laser beam continuously,
the entire surface of the Photosensitive drum is neutralized causing a completely black page
Replace the DC Controller PCA
Defective toner cartridge
Replace the toner cartridge
High voltage contact springs are dirty or defective. The high voltage contacts are mounted on
the High Voltage Power Supply PCA and protrude into the toner cartridge cavity
Inspect and clean the high voltage contacts. If damaged, replace the High Voltage Power Supply PCA.
High voltage power supply circuit is defective (not supplying the correct negative voltage)
Replace the High Voltage Power Supply PCA
some printers have the high voltage power supply on the DC controller.
Laser/Scanner Assembly is faulty (turning laser on continuously)
Replace the Laser/Scanner Assembly
Light is leaking into the printer
Make sure that all covers are in place
possible, but not likely
