RESOLUTION Steps have been created to help replace the cartridge locks, along with timing tips for the main drive assembly. The service kit contains four new locks and four new springs. Replace all the locks, even if they are not broken.

NOTE: Determining if the printer has countermeasured or non-countermeasured cartridge locks can be accomplished by visually inspecting the locks. The countermeasured locks are white in color, the non-countermeasured locks are black.

Parts Required

Replacement Part Number Quantity Description

Q5982-67922 1 Cartridge Lock Kit (to replace all 4 locks at one time) SERVICE ACTION

To Be Performed By: Service Technicians

1. Remove the toner cartridges and ETB.

2. Remove the upper cover (Page 80 in the Service Manual).

3. Remove the right cover (Page 87 in the service Manual).

4. For duplex models: Remove the wires to the duplex fan in the front cover. Simply follow instructions 5 and 6 on page 77 ? 78 in the service manual. This allows for easier removal of the cable harnesses.

5. Unplug the following connectors from the driver PCA and remove the wires from the cable harnesses: a. J209, b. J406, c. J404, d. J213, e. J207, f. J203, g. J402, h. J206, I. J410, j. J208.

6. Remove the interlock switch assembly by removing the one screw attaching it to the chassis. Be aware of the clip at the top and the alignment knob when removing the assembly.

7. Remove the bottom cable harness. There is one screw at the top to remove. Hint: when you reinstall the guide, make sure that the rear locking tab is seated in the sheet-metal chassis. (See page 120 - 121 in the service manual). It may be necessary to disconnect the white door latch from the front door. (Notice the red arrow call-out).

8. Remove the main drive assembly (MDA). There are six screws attaching the MDA to the chassis. Carefully note the locations of the screws to be removed.

CAUTION: Removing the incorrect screws could lead to opening up the MDA, requiring a unit replacement!

NOTE: Two gears may fall off, there are instructions in step 16 on how to align them during the re-installation process.

Remove the metal case by removing two screws. Remove the White Link Arm (see arrow in figure below)

9. Remove the white slide lever by pushing down from the top to release it from the two tabs. Carefully remove the lever by pulling out, be aware that four springs are attached to this lever and the individual cartridge locks.

10. Once the sliding lever is removed, the cartridge locks can be accessed. The new grounding springs are not on the new cartridge locks and will need to be attached. Look at the current springs on the machine for guidance, and at the instructions below. Make sure to feed the hooked end through the hole at the end of the lock to begin with (See figure below.).

NOTE: The service kit has four new locks and four new springs in it, replace all the locks and springs, even if they are not currently broken. The new kit has white colored countermeasured locks. The picture below shows an old black non-countermeasured lock.
