- A software control mechanism has failed.
- At time of fixed reading, the delivery of the preceding original is not over when an original has been
moved and stopped on the right side of the platen roller.
S3 In LDR stream reading, the post-registration roller sensor detects the original when it has been moved
over a specific distance (30 mm) from standby position.
S9,S1 In manual feed mode, the reversal sensor detects an original while the manual feeder registration roller
sensor detects another original.
S7 In stream reading, no change of read position has taken place despite a request for a change of reading
position.
S7 An image lead edge fault condition (0075) has occurred on the 1st sheet.
PI1 The speed setting of the belt motor is the minimum speed (100 mm/sec) or lower or is the maximum
speed (700 mm/sec) or higher.
PI1 At time of a belt motor speed switchover, the belt motor is not operating at a specific speed.
PI1 At time of a switchover of the belt motor state (acceleration, constant, deceleration), the motor is not in
any of the 3 states.
