13) Press in on the bottom tab of the Developer roller plate to release it. See Figure 18

14) 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 19

15) Remove the Developer Roller.

16) 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 20

17) 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.

18) Install the new drum in place. See Figure 21
