Replacing the Drum Cartridge

Replacing the Drum Cartridge

Each drum cartridge can produce about 20,000 A4/Letter-size prints. The actual number of pages obtained from a drum cartridge depends on the image density of the pages you print.

After about 20,000 A4/Letter-size prints, print images start to become faint and blurred. If this happens, use the following procedure to replace the drum cartridge with a new one.

To Replace the Drum Cartridge

1 Turn off the printer and disconnect the power cord from the printer.

2 Close the face-down tray.
