f. EEPROM initializing + all sensors adjustment mode
When the push switch is pressed, the EEPROM is initialized. At that
time, the LED blinks at the cycle of 100msec.
After completion of EEPROM initializing, the LED turns ON. In case of
an error in the EEPROM initializing, the LED blinks at the cycle of
2000msec.
Then all sensors adjustment is started. At that time, the document
remain LED blinks at the cycle of 100msec. After completion of all
sensors adjustment, the document remain LED turns ON. In case of
an. Error in the all sensors adjustment, the document remain LED
blinks at the cycle of 2000msec.
* Only when the EEPROM is successfully completed, the all sensors
adjustment is performed.
Kinds of JAM, error
EEPROM initializing Ready LED blinks at the cycle of
error 2000msec.
All sensors adjustment Document remain LED blinks at the
error cycle of 2000msec
g. Resist sensor adjustment mode
Set the DIP switch (4, 5 to ON, 1, 2, 3 to OFF) and press the push
switch. Each sensor adjustment is performed. At that time, the LED
blinks at the cycle of 100msec.
After completion of the sensor adjustment, the LED turns ON. In case
of an error in the sensor adjustment, the LED blinks at the cycle of
100msec.
Kinds of JAM, error
Sensor adjustment Document remain LED turns OFF.
upper limit error Ready LED blinks at the cycle of
100msec.
Sensor adjustment Document remain LED blinks at the
lower limit error cycle of 100msec.
Ready LED turns OFF
* This mode can be adjusted with SIM 53-2.
h. Timing sensor adjustment mode
Set the DIP switch (1, 4, 5 to ON, 2, 3 to OFF) and press the push
switch. Each sensor adjustment is performed. At that time, the LED
blinks at the cycle of 100msec.
After completion of the sensor adjustment, the LED turns ON. In case
of an error in the sensor adjustment, the LED blinks at the cycle of
100msec.
Kinds of JAM, error
Sensor adjustment Document remain LED turns OFF.
upper limit error Ready LED blinks at the cycle of
100msec.
Sensor adjustment Document remain LED blinks at the
lower limit error cycle of 100msec.
Ready LED turns OFF
* This mode can be adjusted with SIM 53-2.
i. Paper exit sensor adjustment mode
Set the DIP switch (3, 4, 5 to ON, 1, 2 to OFF) and press the push
switch. Each sensor adjustment is performed. At that time, the LED
blinks at the cycle of 100msec.
After completion of the sensor adjustment, the LED turns ON. In case
of an error in the sensor adjustment, the LED blinks at the cycle of
100msec.
Kinds of JAM, error
Sensor adjustment Document remain LED turns OFF.
upper limit error Ready LED blinks at the cycle of
100msec.
Sensor adjustment Document remain LED blinks at the
lower limit error cycle of 100msec.
Ready LED turns OFF
* This mode can be adjusted with SIM 53-2.

(4) Kinds of error (RADF single mode only)
Kinds of JAM, error
Not-reaching/remaining JAM in
the paper feed section
Not-reaching/remaining JAM in
the paper exit section
Paper feed motor lock error
Resist/timing sensor
adjustment error (when power
is supplied)
Paper exit sensor adjustment
error (when power is supplied)
A JAM/motor lock error can be canceled by opening/closing the ADF
after jam recovery process or by applying the power again.

(1) Document lead edge stop position adjustment
·
The ADF document lead edge stop position is adjusted by using
SIM 53.
·
When shipping, the lead edge is set to (8). An adjustment may be
required depending on documents.
The adjustment range is 8mm (8 steps) in the stopper side and
7mm (7 steps) in the glass side. (1mm: 1 step) For each mode of
single, and duplex, the adjustment value can be set independently.
