3-1. Maintenance Precautions
- Before starting disassembly/reassembly or mechanical adjustment, be sure to
disconnect the power cord from the power source.
- Do not replace a fuse with the power switch turned on.
- When replacing a fuse, use the same rating and type since it is provided to prevent fire
and damage to the “Unit, Power Supply”.
- DO NOT adjust VR1, VR2, VR3 and VR4 on the “SA, Main PCB”. (Leave them at the
factory setting condition.) If it is turned, media sensor sensitivity is changed and the
media detection will not be correctly made.
- Do not disassemble/reassemble or adjust the machine, if it functions properly.
Particularly, do not loosen screws on any component, unless necessary.
- After completing an inspection and before turning on the power, be sure to check that
there is no abnormality.
- Never try to print without media.
- Check that the media is properly set.
- Do not lay anything on the cover or lean against it during maintenance or while the
printer is in operation.
- During maintenance, be careful not to leave parts or screws unattached or loose inside
the printer.
- When handling a printed circuit board, do not use gloves, etc., which can easily cause
static electricity. Since ICs, such as CPU, RAM and ROM, might be destroyed by static
electricity, do not touch lead wires or windows unnecessarily.
- Do not put the printed circuit boards directly on the printer or on the floor.
- When disassembling or reassembling, check wires for any damage and do not pinch or
damage them. Also, run wires as they were.
