DISASSEMBLY AND RE-ASSEMBLY
1. SAFETY PRECAUTIONS
To avoid creating secondary problems by mishandling, follow the warnings and precautions
below during maintenance work.
WARNING
(1) Always turn off the power switch and unplug the power cord from the power outlet
before accessing any parts inside the printer.
(2) Some parts inside the printer are extremely hot immediately after the printer is
used. When opening the front cover or rear cover to access any parts inside the
printer, never touch the red colored parts shown in the following figures.
!
CAUTION:
(1) Be careful not to lose screws, washers, or other parts removed.
(2) Be sure to apply grease to the gears and applicable positions specified in this chapter.
(3) When using soldering irons or other heat-generating tools, take care not to accidentally
damage parts such as wires, PCBs and covers.
(4) Before handling any PCBs, touch a metal portion of the equipment to discharge any static
electricity charge on your body, or the electronic parts or components may be damaged.
(5) When transporting PCBs, be sure to wrap them in the correct protective packaging.
(6) Be sure to replace self-tapping screws correctly, if removed. Unless otherwise specified,
tighten screws to the following torque values.

(7) When connecting or disconnecting cable connectors, hold the connector body, not the
cables. If the connector has a lock, release the connector lock first to release it.
(8) After a repair, check not only the repaired portion but also all connectors. Also check that
other related portions are functioning properly before operational checks.
