Parts are controlled as spare parts. When servicing for parts for which no procedures are
described, observe their assembling condition before starting the service.
For optional parts, refer to the manual for them.
Though the optional parts are assumed to be removed, they may not be removed if not
required for the purpose of service operation.
1.1 Before starting service work
Start the work after turning off the power and removing the power cord from the outlet.
Disassemble the device after removing INNER DUPLEX ASSEMBLY (PL5.2.1), OUTER
DUPLEX ASSEMBLY (PL5.3.1) and IMAGING DRUM (PL6.1.1).
When carrying out the work around FUSER, temperature of FUSER and surrounding area
should have cooled sufficiently.
Pay sufficient attention to the parts during work because they may be broken or may not
perform their functions properly if unreasonable force is applied to the parts.
Various kinds of screws are used, so be sure to use the screw at the correct positions. Pay
attention in distinguishing the screws for plastic and for sheet metal. Incorrect use of the
screw type may cause in damaging the screw threads or other troubles.
