6.6.1 Removal and Disassembly
1. Open the Clamshell. Remove any paper present in the printer. Remove the OPC Drum Unit,
the Developer Unit, and the Waste Toner Container.
2. Remove the Front Plastic Paper Guide of the Transfer Charger Assembly by pressing down
on the ends of the Guide and sliding it to the left. This disengages the Locking Tabs and the
Guide can be removed easily.
3. Remove 2 Screws at the rear of the Lower Paper Guide, then remove it from the printer by
lifting the rear out first.
See Figure 6–1. This helps the Guide clear the Transfer Charger
Frame and the Contacts for the HVPS. Disengage the Locking Tabs at the front of the Guide
from the Tension Roller Frame.
4. The Paper Empty Sensor can be removed from the Base Plate by releasing its retaining clips
and removing 1 Screw from the Cable Clamp.
NOTE: The Bottom Cover of the printer must be removed in order to disconnect
the Paper Empty Sensor Cable from the Backplane Board.
5. Place the printer on a phone book or other similar item so that the Bottom Cover edges are
not resting on the item. Press gently to release the 2 Locking Tabs on the right side of the
Bottom Cover, then gently lower this side.
See Detail 6–11. Slide the Bottom Cover slightly to
the right to release the locking tabs on the left side, then lower the Bottom Cover away from
the printer and over the phone book.
