2.2. Disassembly
This section provides the procedures for disasembly of the main components of the
duplexer. You will also find the exploded diagrams in the parts catalogue helpful for this
purpose.
Before proceeding with disassembly, be sure to read the notes below:
Before removing the duplexer from the printer, be sure to turn off printer
power.
Be sure to use the correct screws when installing a component. Using incorrect
screws can result in the threads of the screws being stripped, which may lead
in turn to other problems. Frequent insertion and removal of selftapping
screws can cause damage to screw holes. Do not tighten screws with an exces-
sive torque (force).
When removing or installing circuit boards (PWB), wear a ground wrist strap to
protect against damage due to discharge of stacic electricity.
Gently lift the printer so that it is separate from the duplexer.
Warning--The printer is heavy: Be sure to ask other persons for assistance.
