Ricoh Pro 8300S - Sc507-24; Vacuum Feed LCIT 2: 2 Nd Tray Error (Paper Overload Error)

1.SC Codes
136
 Power of downstream unit is not turned on.
 Tray is overloaded.
 PCB is defective.
 Upper limit sensor 2 is defective or not connected properly.
 Paper height middle sensor is defective or not connected properly.
 Harnesses are damaged.
Solution
In addition to checking for sensor/actuator defect by eye, also execute Input/Output Check as
necessary.
1. Check if the tray is overloaded.
If so, set the paper correctly.
2. Check the connectors of the harnesses related to load detection (lower limit sensor / paper height
middle sensor / upper limit sensor 2)
Reconnect the connectors. Turn the main power OFF and then ON.
3. Check the electrical components related to load detection (lower limit sensor / paper height middle
sensor / upper limit sensor 2)
If they are defective, replace them. Turn the main power OFF and then ON.
4. Check the harnesses (lift motor/Lower limit sensor / paper height middle sensor / upper limit sensor
2)
If the harnesses are defective, replace the harnesses. Turn the main power OFF and then ON.
5. Replace the main PCB. Turn the main power OFF and then ON.

Pattern
B
Error Condition
When Vacuum Feed Banner Sheet Tray is not installed
The following condition has been detected 5 times consecutively.
 During tray initialization, both the upper limit sensor 2 and the lower limit sensor detect after a
certain time elapses.
When Vacuum Feed Banner Sheet Tray is installed
Each of the following conditions has been detected 5 times consecutively.
 During tray initialization, when both the upper limit sensor 2 and the paper height middle sensor
detects, the lift motor lowering starts. However, the upper limit sensor 2 remains detecting although
