0000 Scanner home position cannot be detected
within a specific period of time after the power
switch is turned on or the Start key is pressed.
Caution
No code will be indicated. The keys will be locked. You
can check the code in service mode
(COPIER>DISPLAY>ERR).
- Check if the scanner motor is connected properly, and
replace the scanner motor if necessary.
- Check if the connector (J1720) of the relay PCB is
mounted properly.
- Replace the scanner home position sensor.
- Replace the reader controller PCB.
E204 There is an error in the detection of the image leading edge signal.
0000 During forward movement in fixed reading
mode or during a home position search, the
image leading signal does not occur; or, in
stream reading mode, the image leading edge
signal does not arrive from the ADF controller
PCB.
Caution
No code will be indicated. The keys will be locked. You
can check the code in service mode
(COPIER>DISPLAY>ERR).
- Check if the scanner motor is connected properly, and
replace the scanner motor if necessary.
- Replace the scanner image leading edge sensor.
- Replace the reader controller PCB.
E211 The rise in temperature of the scanning lamp heater is faulty.
0000 While the power is ON, the ambient
temperature of the scanning lamp does not
exceed 10 deg C 2 min after the florescent
heater has gone ON; or, after the power is
turned on, the reading of the ambient
temperature of the scanning lamp is 0 deg C or
lower.
- Check if the connecter (J852, J853) of the light control
PCB is mounted properly.
- Replace the scanning lamp heater.
- Replace the light control PCB.
- Replace the reader controller PCB.
E215 The rise in temperature of the scanning lamp heater is faulty.
0000 While the scanning lamp is OFF, the reading of
the ambient temperature is 170 deg C or
higher.
- Check if the connecter (J852, J853) of the light control
PCB is mounted properly.
- Replace the scanning lamp heater.
- Replace the light control PCB.
- Replace the reader controller PCB.
E218 The scanning lamp is not mounted properly.
0000 When the power is turned on, the absence of
the scanning lamp is detected.
- Check if the scannning lamp is mounted properly.
- Check if the connecter (J1002, J1003) of the inverter
PCB is mounted properly.
- Check if the connector (J1720) of the relay PCB is
mounted properly.
- Replace the scanning lamp.
- Replace the reader controller PCB.
E219 The scanning lamp life
0000 While the scanning lamp is ON, the reading of
the ambient temperature is 170 deg C or
higher.
- Check if the connecter (J852, J853) of the light control
PCB is mounted properly.
- Replace the scanning lamp heater.
- Replace the light control PCB.
- Replace the reader controller PCB.
E220 The lighting of the scanning lamp is faulty.
0000 The scanning lamp does not reach a specific
intensity within 10 sec after it is tuned on (if
the room temperature is 10 deg C or lower,
within 60 sec). Or, the ON detection signal
(FL-DTCT) does not go OFF within 5 sec after
the scanning lamp is turned off; during shading
adjustment, the ON detection signal (FL-
DTCT) does not go ON within 60 sec after the
scanning lamp is turned on.
- Check if the connecter (J852, J853) of the light control
PCB is mounted properly.
- Replace the scanning lamp heater.
- Replace the light control PCB.
- Replace the reader controller PCB.
E222 The rise in temperature of the scanning lamp heater is faulty.
0000 During the initial activation after power-on,
the reading does not reach 70 deg C within 5
min after the heater is turned on. Or, during
standby or reading operation, the reading does
not reach 75 deg C within 3 min after the
heater is tuned on.
- Check if the connecter (J852, J853) of the light control
PCB is mounted properly.
- Replace the scanning lamp heater.
- Replace the light control PCB.
- Replace the reader controller PCB.
E240 The communication between the MCON and DCON is faulty.
0000
0001
0002 A communication fault exists between the
CPUs of the main controller PCB and the DC
controller PCB. - Check the wiring between the DC controller PCB and
the main controller PCB.
- Replace the DC controller PCB.
- Replace the main controller PCB.
E241 The communication between the original orientation detection PCB and RCON is faulty.
0000 The initial communication between the CPUs
of the original orientation detection PCB and
the reader controller PCB fails.
- Replace the original orientation PCB.
- Replace the reader controller PCB.
