1.SC Codes
311
Pattern
B
Error Condition
During tray initialization or paper feed operation, before the pickup solenoid is turned on, the upper limit
sensor detects that the 2nd tray is not at the upper limit position, for five times consecutively.(From the
first to fourth times, message is displayed asking to set the paper again. An SC is issued the fifth time
this occurs.)
Major Cause
 Power of downstream unit is not turned on.
 Paper overload
 The pick-up roller was pushed down physically.
 The spring of the pick-up roller solenoid is released.
 2nd upper limit sensor / connector is disconnected.
 Harness is damaged.
 Main controller board is defective.
Solution
1. Remove all paper from the cover interposer tray. Turn the power off and on, and then check if other
SCs occur.
2. Set a sheet on the tray generating the SC, and check tray operation.
From the first to fourth times, operator will be prompted to set the paper again.
A: The bottom plate is not lifted. When the corresponding cover interposer tray is selected, operator
will be prompted to set the paper again.
B: The pick-up solenoid operates but the bottom plate is not lifted. The operator will be prompted to
set the paper again.
Cause: A
 Pick-up solenoid was pushed down physically.
 The spring of the pick-up solenoid released (pick-up roller lowered) or defective.
 2nd upper limit sensor connector is disconnected/half-inserted, defective.
 2nd upper limit sensor harness with the relay connectors is disconnected/half-inserted, or
damaged.
Cause: B
 Too much paper is loaded on the tray (overloaded)
 Pick-up solenoid harness with the relay connectors is disconnected/half-inserted, or damaged.
 2nd upper limit sensor is defective.
 Main controller board is defective.
3. Check if the pick-up solenoid has been pushed down by the loaded paper or other objects. If so,
remove the obstacle.
