Mechanical Components

If you service a driving assembly (e.g., gears), first turn off the power
and unplug the power cord. Then manually rotate the assembly.
Do not touch the driving part (e.g., gears) while the
assembly (printer) is being driven.
Safety Components
The printer is equipped with safety components (e.g., interlock
switches, fuses, thermostat) and safety switches for protecting users
and service personnel from injury and the equipment from damage.
The printer has two interlock switches, two safety switches and two
interlock connectors that serve as the main safety mechanism.


Front Cover Switch R
This switch is turned off when the Front Cover Assembly is opened.
It cuts off the power supply (24VDC, 5VDC-LD) from the power
supply unit to stop all operations and disconnects the output (5VDC-
LD) circuit from the power supply and stops the laser beam
emission.
This switch consists of the following two switches:

A switch that cuts off the power supply (24VDC, 5VDC-LD) to
the control circuits and related parts.

A switch that directly cuts off the power supply circuit (5VDC-LD)
to the laser beam output circuit.


Front Cover Switch L
This is a safety switch. This switch is turned off when the Front
Cover Assembly is opened, causing the printer without control units
to stop operating.


Top Cover Switch
This is an interlock switch that directly cuts off the power supply
(5VDC-LD) circuit to the laser beam output circuit. This switch is
turned off when the Top Cover Assembly is removed, cutting off the
output (5VDC-LD) circuit from the power supply unit and stopping
the laser beam emission.
