5. Remove the four screws on the right side end cap. Remove the end cap.

6. Remove the PCR. 7. Also on the right side there is a series of gears under the end

cap. Make a note of the location of each gear, and remove

them. Clean the PCR with your normal PCR cleaner.

WARNING: Do not clean the OEM PCR with alcohol, as this will

remove the conductive coating from the roller. If the PCR is an

aftermarket, follow the cleaning methods recommended by

the manufacturer. If the PCR is an OEM, we recommend it be

cleaned with your standard PCR cleaner.

9. With the PCR cleaner assembly removed, the drum can

easily be removed by lifting it out. Clean out any remaining

toner from the cartridge.

10. Press in on the bottom tab of the developer roller plate

(right gear side) to release it.

8. There are two screws on the PCR cleaner assembly. Remove them and gently pry the blade up. Be careful not to damage the

alignment pins. This PCR cleaner also has what can be considered a wiper blade. It is a very flimsy blade attached to the metal

bar. Wipe this blade down with a clean lint free cloth before re-installing. It is very important that the PCR cleaner be cleaned.

Vacuum or blow off any residual toner from the foam/felt.

11. With a small common screwdriver, press the entire plate

towards the edge of the developer roller cavity, and lift up. The

plate should come loose.

12. Gently pry out the roller plate from the cartridge. The foam

seal, and possibly a plastic flat washer will come out with it. Be

careful not to damage the foam seal, or loose the flat washer.

13. Remove the developer roller.

Be careful not to damage or lose the flat washers on the roller.

14. 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 alco-

hol, 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 doctor blades are available, they will

have to come with replacement foam.

15. Replace the developer roller, and flat washers. 16. If no grease is left on the gears and gear shafts, or it is

contaminated with toner clean it all off. Replace it with white

lithium grease. Be sure to clean and grease the gear shafts,

and inside the gear.

17. Install the roller plate.

Make sure the tab is locked in place.

18. Replace the roller plate and seven gears. Look carefully at

the picture of the gears. Each gear must fit in this exact way.

The gears labeled in order of installation.

end cap and replace with fresh grease. Replace the end cap

23. Install the right side end cap, and four screws. Make sure

the PCR fits correctly in its holder and all the gears are aligned.

24. Fill the hopper with the appropriate amount of toner. This

can also be done through the fill plug, but the fill plug tends to

leak and will probably have to be sealed with silicon.

25. Replace the chip. Make sure the chip you install is the

correct one for the machine it is to be installed in. New reset

boxes are now available that can change the personality of the

chip across the full line. This will enable you to test the

cartridge in your test machine, and than change the chip to

work in your customer’s machine if different.
