CHAPTER 3 EXPOSURE SYSTEM
VII.DISASSEMBLY/ASSEMBLY
Make sure of the following when disassembling or assembling the machine:
1.When the control panel soft switch (front of the reader unit) is turned off, the fans
will operate for about 30 min to cool the machine (so as to prevent caking of toner).
Be sure to perform either of the following in addition to disconnecting the power plug:
? Wait for 30 min after turning off the control panel power soft switch (right of the read-
er unit control panel); or
? Turn off the control panel soft switch and the reader unit rear power switch (right of
the reader unit rear), and remove the fixing assembly of the printer unit.
2. Assemble the parts by reversing the steps used to disassemble them, unless other-
wise mentioned.
3. Identify the screws by type (length, diameter) and location.
4. Do not leave out the toothed washer that comes with one of the mounting screws on
the rear cover to protect against static electricity.
5. Do not leave out the washer that comes with the screw used for the grounding wire
and the varistor to ensure electrical continuity.
6. Do not operate the machine with any of its parts removed, unless otherwise men-
tioned.
7. Touch the copier's metal section before starting the work to discharge the build-up of
static electricity so as to prevent static damage before handling any PCBs.
Note:
All illustrations in this chapter assume that the reader assembly is mounted on its
rack.
