(1) Precautions
Before disassembling the main unit, press the main power switch to turn the power off. Make sure that the power
lamp on the operation panel is off and unplug the power cord from the wall outlet. Then, start the disassembly.
When handling the PWBs (printed wiring boards), do not touch parts with bare hands. Make sure not to damage the
PWB.
If ICs are mounted on the PWB, do not touch them by hand or something charged with electrostatic.
Make sure to release the hook before disconnecting the connector with the hook.
Take care not to pinch up the wire and cable.
Use the original screws when reassembling the parts which have been disassembled.
If the types and the sizes of screws are not sure, refer to the parts list.

Note the following point when handling and storing the drum.
When detaching the drum unit from the main unit, take care that extreme strong direct light does not expose on the
drum surface.
Store in the following place of ambient temperature of -20 to 40 degree C(-4°F to 104°F) and ambient humidity of
85% RH or less. Wait more than 5 seconds between the power off and on. Avoid storing the drum unit in the place
where the temperature and humidity may suddenly change even if these changes are within the tolerable range.
Avoid exposure to any substance which is harmful or may affect the quality of the drum.
