Ricoh A095, Service Manual

Page: 339 / 680

SYMPTOM:
PCB’s and/or Power Pack damage.
CAUSE:
When units such as the drum unit or transfer belt unit are removed while the main switch is
turned "ON", electrical noise or surge current might occur resulting in PCB damage.
SOLUTION:
Replace the damaged PCB or Power Pack.
CAUTION: Turn "OFF" the main switch before disconnecting the
connector or removing the unit
SYMPTOM:
The Sorter Stapler does not staple even if the staple mode is selected.
CAUSE:
If direct sunlight strikes the bin jam sensor to (a photo transistor), it causes the sensor to
malfunction and disregard the staple command.
SOLUTION:
1. Avoid installing the machine in direct sunlight.
2. Install a piece of mylar around the bin-jam sensor to protect it from direct sunlight.
SYMPTOM:
SC502, 508, 510, 511
CAUSE:
1. When the tandem paper tray is closed roughly, it bounces slightly to the front
disengaging the drawer connectors.
2. When the customer pulls out the tandem tray to clear a misfeed, paper may drop behind
the tray. The paper is then caught in the drawer connector at the rear side of the right
tandem tray when the tray is pushed back in.
SOLUTION:
1. Instruct the operator to gently push the tandem tray until it stops. If any of the above
mentioned Service Codes are present, instruct the operator to pull the tray out and gently
push the tray back in until it stops and then turn the main switch "OFF" and then "ON".
Apply silicone grease (G-501) to the points called out in the illustrations below. This
reduces the friction between the tandem tray and the guide rail which helps the lock lever
to position the tandem tray at the correct position. If the tandem tray bounces slightly to
the front, the lock lever pushes the lock plate to move the tray back to the correct
position.
