Safety Switch - Ricoh G157 Service Manual

OPTICAL HOUSING UNIT

6.4.6 SAFETY SWITCH

The copier has three safety switches
[A][B][C]. They all go on when these covers
are closed:
[A]: Rear cover
[B]: Center cover
[C]: Front cover
These covers have a hook or a
protruding part that is attached to a
safety switch:
• Rear cover–in the front left corner
[a]
• Center cover–on the bottom side
near the left end [b]
• Front cover–at the top end near the
right end [c]
The lever on the front cover [E] is
attached to the hook [c]. When you pull the lever (the front cover stays closed), the
hook releases one more lever [D] on the machine front. The safety switch [C] goes
off. In other words, the safety switch [C] goes off before you open the front cover.
On the other hand, the lever on the rear cover [F] is not attached to a safety switch.
The copier can operate even when you pull the lever (if the rear cover stays
closed).
NOTE: The center cover does not have such a lever.
