Separate the Cartridge Halves:

1. Remove the pins that hold the cartridge halves together (one on each side).

If the pins are protruding from the cartridge, pull them out with pin pliers. If
not, turn the cartridge over and use a jeweler's screwdriver to push the pins
inward until the halves can be separated. Note: The inverted position
prevents the pins from falling onto the surface of the drum. To simplify later
pin removal, replace with a headed pin. Fig. 1 Set aside the toner hopper unit.

Disassemble the OPC Unit:

2. Use pliers to remove the flat head drum axle at the gearless end of the drum

and gently pull the drum out and away from the other drum axle. Once the
drum is removed, push out the remaining axle. Inspect the drum for defects.

If defects are detected, replace the drum with Oasis PN: AXDR20, or
AXDR10. If the drum appears to be intact, gently clean with compressed air
and a soft cloth.

3. Grasp each shaft end of the PCR and lift it from the saddle clips. Use com-

pressed air to remove residual toner from the surface of the PCR and inspect
for defects. Replace if necessary. If the PCR is intact, wipe the surface with
Nu-Finish® and a clean, lint-free cloth.

4. Locate and remove the two screws holding the wiper blade in place. Use

compressed air to remove excess toner, and inspect for wear/defects. You
may also use a lint-free cloth saturated with 99% Isopropyl Alcohol to remove
any residual toner from the blade. If the blade is damaged, replace with
Oasis PN: AXWB20.

5. Empty out the remaining toner from the wastebin. Remove residual toner with

compressed air; be careful not to damage the recovery blade. If the recovery
blade is kinked, nicked, or loose, replace it with Oasis PN: AXRB10. Clean
the PCR saddle clips with swabs saturated with 99% IPA.

6. Reinstall the wiper blade and PCR. Lubricate the drum with padding powder

and place it into the cartridge. Replace the drum axles and rotate the drum
against the wiper blade to lubricate it. Use compressed air to remove excess
powder and set the drum unit aside.

Dissasemble theToner Hopper Unit:

8. Locate and remove the screws holding the end caps on (one on each side).

Pull off the caps and note the gear position for reassembly. Grasp each end
of the magnetic roller and gently lift it from the lift the hopper unit. Use com-
pressed air to remove toner from the mag roller, and wipe off any residual
toner with a lint-free cloth. Oasis does not recommend using any type of
solvent to clean the mag roller. Do not touch the coated area of the mag
roller with bare hands. Set the mag roller aside on a clean cloth.

7. Remove the hopper plug and vacuum out the remaining toner. Locate and

remove the two screws securing the doctor blade in place. Clean the blade
with a lint-free cloth and inspect for wear/damage. Replace if necessary.

8. If you are not going to seal the cartridge, move on to step #9.

a. Locate the small flat rubber seal plug on the fill end of the hopper and use

jeweler's screwdriver to push the plug out from inside the hopper. This
will allow the pull end of the seal to pass through the opening. Note: Be
sure the old seal is completely removed and the area is clean before
installing a new seal.

b. To apply an Oasis seal PN:AXSL10, remove the seal backing and align

it against the edges of the hopper. Then fold the pull-end of the seal back
and through the opening. Replace the rubber plug.

9. Replace the doctor blade (2 screws), developer roller, gears, and gear end

cap. Hold the developer roller in place at the plug end to stop leakage and fill
with new toner. Then reinstall the plug and end cap.

10. Join the cartridge halves together and reinsert pins.
