6. Remove the interlock switch assembly by r emoving 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 scre w at the top to remove.
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.
Remove the metal case by removing two screws. Remove the White L ink 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.
11. To attach the cartridge lock, hook the square part of the grounding spring to the metal chassis, then pull down and attach the lock on the metal shaft. NOTE: Replace all four cartridge locks, even though the others may not be broken. If one lock experienced failure, the others are more prone for failure later.
13. The slide lever and cartridge locks should look like the picture below when all is in pl ace. 14. Lock the white slide lever in place by installing the metal case and white plastic piece . Make sure to insert the flange of the sheet metal in the slot on the sheet metal, and place the white shaft in the while slide lever.
15. Connect the four springs on the white slide lever to each of the individual cartridge locks (start from the middle ones, it is easier that way). You will need needle-nosed pliers with pointed tips. The spring on the top is attached; the one on the bottom is not attached.
NOTE: If this procedure has been properly followed, in the back of the printer, you will see the 4 white cams that control the movement of developers (see figure below). On the top and bottom shafts, you can see a black plastic part that has a flag associated with it.
17. Prepare the MDA for installation. Two areas must be checked: a. Make sure that all the white shafts are pushed to the right (clockwise) when the MDA is oriented as shown below (See the blue arrows in the image below.). The shafts are aligned correctly in the picture.
b. Next, pay attention to the area marked with the two red arrows, enlarged in the picture below. It is possible that during the handling of the MDA one or both of these two gears can be mis-positioned by accident. If this happens, one or more of the color planes could be missed during printing.
holes from larger gears should both be showing as illustrated by the red circles . (The large gears are under the frame and driven by the smaller gears.) 18. With the above in alignment, install the main drive assem bly. Start at the left side, inserting the MDA into the metal slots and rotate it into position.
20. At this point, reverse steps 7 on down. This will have the printer back up and running. Remember to correctly thread the cables through the wire harnesses properly! NOTE: The connector to the top cov er is different between the sim plex and duplex models.
