(6) Thin paper duplex paper pass mode
When originals are set on the paper feed tray, the original feed LED
lights up. When the push switch is pressed, all the originals on the
tray are fed.
(7) Load check mode
Every time when the push switch pressed, the following operation is
performed in sequence repeatedly.
1. Read LED/Original remain LED ON, paper feed motor reverse
rotation (500mm/sec)
2. Operation stop
3. Ready LED/Original remain LED ON, paper feed motor forward
rotation (250mm/sec)
4. Operation stop
5. Ready LED/Original remain LED ON, electromagnetic clutch
ON, transport motor forward rotation (800mm/sec)
6. Operation stop
7. Ready LED/Original remain LED ON, electromagnetic clutch
ON, transport motor forward rotation (250mm/sec)
8. Operation stop
9. Ready LED/Original remain LED ON, electromagnetic clutch
ON, transport motor forward rotation (800mm/sec)
10. Operation stop
11. Ready LED/Original remain LED ON, electromagnetic clutch
ON, transport motor forward rotation (250mm/sec)
12. Operation stop
13. Ready LED/Original remain LED ON, electromagnetic clutch
ON, paper feed motor synchronization forward rotation
(800mm/sec)
14. Operation stop
15. Ready LED/Original remain LED ON, shutter solenoid ON
16. Operation stop
17. Ready LED/Original remain LED ON, weight solenoid ON
18. Operation stop
19. Ready LED/Original remain LED ON, electromagnetic clutch ON
20. Operation stop
21. Ready LED/Original remain LED ON, electromagnetic brake ON
22. Operation stop
23. Ready LED/Original remain LED ON, flapper solenoid ON
24. Operation stop
25. Ready LED/Original remain LED ON, shutter solenoid ON,
weight solenoid ON, paper feed motor reverse rotation
(500mm/sec)
26. Operation stop

(8) EEPROM initia all sensors adjustment
mode
When the push switch is pressed, the EEPROM is initialized. At that
time, the LED blinks in the cycle of 100msec. After completion of
initializing of the EEPROM, the LED turns ON. If there is an error in
initializing of the EEPROM, the LED goes off. After initializing the
EEPROM, adjust the resist sensor, the timing sensor, and the paper
reversing sensor.
Jam / Error LED display
EEPROM initializing error Ready LED/Original remain
LED OFF
(9) Resist sensor adjustment mode
(10) Timing sensor adjustment mode
(11) Paper reversing sensor adjustment mode
When the push switch pressed, the adjustment of each sensor is
started. At that time, the LED blinks in the cycle of 100msec. After
completion of the adjustment, the LED turns ON. If there is an error in
the adjustment, the LED blinks in the cycle of 100msec.
Jam / Error LED display
Sensor adjustment
upper limit error Original remain LED blinks in the cycle
of 100msec. Ready LED goes off.
Sensor adjustment
lower limit error Original remain LED goes off. Ready
LED blinks in the cycle of 100msec.
5. Kinds of errors (RADF single mode
only)
The table below lists the kinds of Jam / Errors and LED display
examples.
To cancel the JAM/motor lock errors, cancel the JAM and open/close
the ADF, or supply the power again.
Jam / Error LED display
Not reached/remaining JAM in the
paper feed section Original remain LED blinks
in the cycle of 100msec.
Not reached/remaining JAM in the
paper feed section Ready LED blinks in the
cycle of 100msec.
Paper feed motor lock error Original remain LED blinks
in the cycle of 200msec.
Paper exit motor lock error Ready LED blinks in the
cycle of 200msec.
Resist/timing sensor adjustment
error (when supplying the power) Original remain LED blinks
in the cycle of 100msec.
Paper reversing sensor adjustment
error (when supplying the power) Ready LED blinks in the
cycle of 100msec.
