Gently pry out the roller plate from the cartridge. The foam seal, and plastic flat washer will come out
with it. Be careful not to damage the foam seal, or loose the flat washer. See Figure 18

Remove the Developer Roller.

It is highly recommended that the Doctor Blade be cleaned. Failure to do so will cause streaking. The
Doctor Blade can be cleaned with out removing it. Dampen a cotton swab with alcohol, and clean the
blade. Be careful not to press too hard and damage the blade. If the blade has a heavy buildup of
toner on it, clean it with Acetone, and then alcohol. Removing the blade is difficult because of the foam
seals attached. If the seals are torn, the cartridge will leak. That is why we do not recommend it. Once
replacement Dr. Blades are available, they will have to come with replacement foam. See Figure 19
18.
Replace the Developer roller, roller plate and gears. If no grease is left or it is contaminated with toner,
clean it all off, and replace it with white lithium grease. Be sure to clean and grease the gear shafts,
and inside the gear.
