Instructions:

Separate the Toner Hopper and OPC Drum Unit:

1. Use a spring hook to remove the tension spring connecting the toner hopper

and OPC drum unit (Fig 1).

2. Invert the cartridge (so that the drum shutter is facing up) and locate the lock-

ing pins on each side. This position will prevent the locking pins from falling

onto the surface of the OPC drum when they are pushed in. Push the pins

forward into the cartridge with a jeweler’s precision screwdriver (Fig 2).

Separate halves and set aside the OPC drum unit.

screws holding the gear cover in place (Fig 3A). Make a note of the gear

position for re-assembly.

side. (Fig 3B). Clean off any conductive grease around the contact point with

alcohol and a cotton swab.

2. Gently lift the magnetic roller from the toner hopper assembly (Fig 4).

3. Clean the magnetic roller and bushings with compressed air. Note: Make

sure the conductive plastic at the end of the mag roller is clean.

4. Locate and remove the two screws securing the doctor blade. Now,

gently pry the right or left side of the metal piece with a flathead

screwdriver until the blade lifts up (Fig 5).

5. Inspect the adhesive strip on the blade for wear. (Replace if necessary). Use

a blower to remove excess toner.
