3) Precautions for disassembly and adjustment
•
Unplug the power before disassembling the machine.
•
Do not operate the machine with the parts removed.
Be careful not to have your clothes caught in the gears, belts and so on when
you need to operate the machine without covers.
•
Do not connect or disconnect any connector on the PCBs while electricity is
turned ON.
•
Do not use a vacuum cleaner to clean sensors. It may cause electrostatic
damage.
Use the blower brush and cotton swab instead. Remove sensors beforehand
when cleaning the unit.
•
For the drum, follow "1.8 Precautions of consumables"
•
Make sure to use the correct screw sizes. Do not mix them up.
•
Use toothed lock washer to install ground wires for electrical continuity.
•
Reassemble parts in the reverse sequence of the disassembly unless otherwise
noted.
•
Replace blown fuses with the specified rated ones.
<< Precautions of laser beam >>
Laser beam never leaks out in operation because the optics system used in the
machine is contained completely in the protection housing and the out cover. However,
follow the instructions below while performing maintenance service.
1. Do not insert tools like very reflective drivers directly into the laser beam path.
2. Take off metal-made accessories like watches and rings.
(The laser beam may be reflected and get into eyes.)
Be very careful for the laser beam is invisible.
