screws that hold the developer roller end cap
to the toner hopper. (See Photo 31) Remove
the end cap.
Step 36
The next steps will fill the toner car-
tridge with the supply roller in place
using the Mag Funnel. Place toner
cartridge into holding device or fix-
ture. Place the Mag Funnel in the
opening for the developer roller.
Holding the Mag Funnel in one
hand, pour the toner with the other
hand. (See Photo 35)
NOTE: Look inside of toner car-
tridge to ensure the agitator blade
is not blocking opening. Move the
agitator drive gear to move the
blade into the correct position.
Photo 32
Step 32
Lift the developer roller from the toner car-
tridge. Remove the white bushings from the
ends of the developer roller. (See Photo 32)
Step 33
Install the drive gear end on the developer
roller axle into a drill motor and tighten in the
chuck. Clean the developer roller using a lint-
free cloth and 99% alcohol while the roller is
rotating in the drill. (See Photo 33) Once the
roller is clean, go over the roller again using
distilled water and a soft lint-free cloth. Make
several passes. Dry the roller using a dry, soft
lint-free cloth.
NOTE: The surface of the developer roller may
change and become wrinkled. If properly
cleaned, the developer roller will go back to its
original state when finished with the cleaning
process.
