Precautions for maintenance/disassembly

(1)

Precautions for disassembly

Observe the following precautions whenever servicing the printer.
• Be sure to unplug the printer from the outlet before attempting to service the printer.
• To reassemble the printer, reverse the order of disassembly unless otherwise specified.
• The basic rule is not to operate the printer anytime during disassembly. If it is absolutely neces-
sary to run the printer with its covers removed, use care not to allow your clothing to be caught in
revolving parts such as the gears, rollers and motor.
• Never touch the terminals of electrical parts or high-voltage parts such as the high voltage unit.
• Be sure to handle the fusing unit carefully as the unit is still hot for a while after the printer is
stopped.
• Always unplug connectors by holding the connector housing.
• Be sure to use the fuse of the specified rating
• Do not forget to install the ground wire or ground plate to ensure positive conduction. Install the
screw with a toothed washer in the right position at reassembly.

Parts that must not be touched

• Never disassemble or adjust the print head unit or the mirror unit.
• Never remove, disassemble, or adjust the parts with mounting screws that are painted red.

During transportation/storage the PWBs with MOS ICs:

The following precautions must be observed when handling circuit boards with MOS (metal oxide
semiconductor) ICs.
• During transportation or when in storage, new circuit boards must not be indiscriminately
removed from their protective conductive bags.
• Do not store or place circuit boards in a location exposed to direct sunlight.
• When it becomes absolutely necessary to remove a board from its conductive bag or case, always
place it on its conductive mat in an area as free as possible from static electricity.
(4)

During replacement the PWBs with MOS ICs:

• Before unplugging connectors from the circuit boards, make sure that the power cord has been
unplugged from the power outlet.
• When removing a board from its conductive bag or case, do not touch the pins of the ICs or the
printed pattern. Place it in position by holding only the edges of the board.
• Before plugging connectors into the board, make sure that the power cord has been unplugged
from the power outlet.
