Replace the MCU PWB. (PL13.1)
009-361 DRUM COMMUNICATION FAILURE (M)
Description
A communication failure with the DRUM was
detected.
BSD on : CH9.3 CH9.31B
Procedure
Run
DC330
[009-152].
Is H displayed?
Y
N
Check the installation status of the DRUM and the wire
between the DRUM (M) J152 and the MCU PWB J405 for
an open circuit and poor contact. If no problems are found,
replace the DRUM (M). (PL4.1)
Replace the MCU PWB. (PL13.1)
009-362 DRUM COMMUNICATION FAILURE (C)
Description
A communication failure with the DRUM was
detected.
BSD on : CH9.4 CH9.31B
Procedure
Run
DC330
[009-153].
Is H displayed?
Y
N
Check the installation status of the DRUM and the wire
between the DRUM (C) J154 and the MCU PWB J405 for
an open circuit and poor contact. If no problems are found,
replace the DRUM (C). (PL4.1)
Replace the MCU PWB. (PL13.1)
009-363 DRUM COMMUNICATION FAILURE (K)
Description
A communication failure with the DRUM was
detected.
BSD on : CH9.4 CH9.31B
Procedure
Run
DC330
[009-154].
Is H displayed?
Y
N
Check the installation status of the DRUM and the wire
between the DRUM (K) J153 and the MCU PWB J405 for
an open circuit and poor contact. If no problems are found,
replace the DRUM (K). (PL4.1)
Replace the MCU PWB. (PL13.1)
009-380 ATC SENSOR FAILURE (Y)
Description
The ATC SENSOR (Y) failure Or the failure was
also detected when the amount of the developer material
becomes low or the Auger of the Developer cannot revolve due
to a faulty motor.
BSD on : CH9.10 CH9.31C
Procedure
Perform the ATC measurement of the
DC922
TRC Control. (If
this measurement cannot be performed, rewrite the value of the
DC131
[752-324] to 2. After the measurement has completed,
restore the value.)
Is the FAILURE judgement of the ATC SENSOR (Y) OK?
Y
N
Check the installation status of the ATC SENSOR and the
wire between the ATC SENSOR P129 and the I/F PWB
J534 for an open circuit and poor contact. If no problems
are found, replace the ATC SENSOR. (PL6.2)
After checking that no failures are detected during normal
operation, end the Diag.
009-381 ATC SENSOR FAILURE (M)
Description
The ATC SENSOR (M) failure. Or the failure
was also detected when the amount of the developer material
becomes low or the Auger of the Developer cannot revolve due
to a faulty motor.
BSD on : CH9.11 CH9.31C
Procedure
Perform the ATC measurement of the
DC922
TRC Control. (If
this measurement cannot be performed, rewrite the value of the
DC131
[752-324] to 2. After the measurement has completed,
restore the value.)
Is the FAILURE judgement of the ATC SENSOR (M) OK?
Y
N
Check the installation status of the ATC SENSOR and the
wire between the ATC SENSOR P130 and the I/F PWB
J534 for an open circuit and poor contact. If no problems
are found, replace the ATC SENSOR. (PL6.2)
After checking that no failures are detected during normal
operation, end the Diag.
009-382 ATC SENSOR FAILURE (C)
Description
The ATC SENSOR (C) failure. Or the failure was
also detected when the amount of the developer material
becomes low or the Auger of the Developer cannot revolve due
to a faulty motor.
BSD on : CH9.12 CH9.31C
Procedure
Perform the ATC measurement of the
DC922
TRC Control. (If
this measurement cannot be performed, rewrite the value of the
DC131
[752-324] to 2. After the measurement has completed,
restore the value.)
Is the FAILURE judgement of the ATC SENSOR (C) OK?
Y
N
Check the installation status of the ATC SENSOR and the
wire between the ATC SENSOR P131 and the I/F PWB
J534 for an open circuit and poor contact. If no problems
are found, replace the ATC SENSOR. (PL6.2)
After checking that no failures are detected during normal
operation, end the Diag.
To clear this fault, clear the value of
DC131
[752-
109] to "0".
