malfunction
• The Scanner Home Position Sensor (PC6) does not
go from HIGH to LOW when the Scanner Motor (M5)
is energized for a given number of steps after the
sequence to bring the Scanner back to its home position has been started at the end of a scan motion and
during re-shading.
• The Scanner Home Position Sensor (PC6) does not
go from LOW to HIGH when the Scanner Motor (M5)
is energized for a given number of steps after a scan
motion has been started at the end of a Scanner
Home Position Sensor home check scan motion and
during re-shading.
If the Upper Home Position Sensor is LOW during an initial operation:
• The Lower Home Position Sensor (PC33) is LOW
when the Bin Switching Motor (M1) starts turning forward.
• If the Lower Home Position Sensor (PC33) does not
go LOW at a time 2.5 sec. after the Bin Switching
Motor (M1) has started turning forward, the Bin
Switching Motor is kept deenergized for a given
period of time and then energized again to turn backward. The Upper Home Position Sensor (PC32) does
not go LOW after the motor has started turning backward.
• The Upper Home Position Sensor (PC32) does not go
HIGH at a time 1 sec. after the Bin Switching Motor
(M1) has started turning forward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Upper Home Position Sensor (PC32)
does not go LOW at a time 2.5 sec. after the motor
has started turning backward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Lower Home Position Sensor (PC33)
does not go HIGH at a time 1 sec. after the motor has
started turning backward.
If the Lower Home Position Sensor is LOW during an initial operation:
• The Upper Home Position Sensor (PC32) does not go
LOW at a time 2.5 sec. after the Bin Switching Motor
