CHAPTER 1: MAINTENANCE
Electrical system work
> After removing wire bundles, fasten them with
wire bundle bands (bar lock ties) so that they
will not sag.
> When installing parts, be careful to avoid
pinching or damaging the wire bundles.
> If a fuse blows, always replace it with one with
the specified capacity.
> Using a fuse with a larger capacity can not only
damage parts, but may cause fires.
> Be careful not to drop image scanners, thermal
print heads, and other sensors as they can be
easily damaged.

Sensor types
> Photoelectric sensors may be broadly divided
into the following four types: interrupt types
(U-shaped), actuator types, reflective types,
and transmitting types.
> Magnetic sensors use Hall ICs, which react to
the magnetic force in magnets.
> Always turn off the power before plugging or
unplugging sensor connectors.

Switch types
> Micro-switches may be divided between
normally open (N.O.) types and normally
closed (N.C.) types.
> With an (N.O.) connection, an internal contact
is connected when the switch actuator is
pressed.
> With an (N.C.) connection, an internal contact
is disconnected when the switch actuator is
pressed.

Note
The machine is comprised of many gears. When inspecting or replacing parts, apply grease to the gears.
If they are not properly greased, the gears may make abnormal sounds, and malfunctions or mechanical
problems may occur.
