• Between the I/F PWB J536-B3 and ENVIRONMENT
SENSOR J255-2
• Between the I/F PWB J536-B4 and ENVIRONMENT
SENSOR J255-1
Is the resistance 1 Ohm or less for all wires?
Y
N
Check for an open circuit and poor contact.
Replace the ENVIRONMENT SENSOR. (PL1.3)
Replace the I/F PWB (PL9.1) and MCU PWB (PL13.1) in
sequence.
009-670 New Toner Detect (K)
Description
It was detected that the Toner Cartridge has been
replaced with a new one. (Hidden Failure)
BSD on : CH9.14 CH9.31D
Procedure
If too many of this Code are found in the Failure History, go to
the 009-390 FIP to repair the trouble.

Description
It was detected that the Toner Cartridge has been
replaced with a new one. (Hidden Failure)
BSD on : CH9.14 CH9.31D
Procedure
If too many of this Code are found in the Failure History, go to
the 009-391 FIP to repair the trouble.
009-672 New Toner Detect (M)
Description
It was detected that the Toner Cartridge has been
replaced with a new one. (Hidden Failure)
BSD on : CH9.14 CH9.31D
Procedure
If too many of this Code are found in the Failure History, go to
the 009-392 FIP to repair the trouble.
009-673 New Toner Detect (Y)
Description
It was detected that the Toner Cartridge has been
replaced with a new one. (Hidden Failure)
BSD on : CH9.14 CH9.31D
Procedure
If too many of this Code are found in the Failure History, go to
the 009-393 FIP to repair the trouble.
009-684 ADC SHUTTER FAILURE
Description
An operation failure of the ADC SHUTTER
BSD on : CH9.16 CH9.31D
Procedure
Run the
DC330
[009-078].
Was the ADC SHUTTER SOLENOID actuated?
Y
N
Is +24 VDC measured between the I/F PWB J536-A7 (+)
and GND (-)?
Y
N
Check the +24 VDC circuit to the I/F PWB J536-A7
by referring to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1) (WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3) (WN4.3.16 +24 VDC-4)
Run the
DC330
[009-078].
Is 0 VDC measured between the I/F PWB J536-A8 (+) and
GND (-)?
Y
N
Check the wire between the I/F PWB J536-A8 and
the ADC SENSOR UNIT J602-3 for an open circuit
and poor contact. If no problems are found, replace
the I/F PWB (PL9.1) and the MCU PWB (PL13.1) in
sequence.
Run the
DC330
[009-079].
Has the voltage between the I/F PWB J536-A6 (+) and
GND (-) changed to 0 VDC momentarily?
Y
N
Check the wire between the I/F PWB J536-A6 and
the ADC SENSOR UNIT J602-1 for an open circuit
and poor contact. If no problems are found, replace
the I/F PWB (PL9.1) and the MCU PWB (PL13.1) in
sequence.
Check the wire between the I/F PWB J536 and the ADC
SENSOR UNIT J602 for an open circuit and poor contact.
If no problems are found, replace the ADC SENSOR
ASSY. (PL1.3)
After checking that no failures are detected during normal
operation, end the Diag.
009-910 DRUM TYPE MISS MATCH (K)
Description
DRUM Type Mismatch
BSD on : CH9.4 CH9.31B
Procedure

DC330
[009-154].
Is H displayed?
Y
N
Check installation status of the DRUM.
Check 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)
009-911 DRUM TYPE MISS MATCH (C)
Description
DRUM Type Mismatch
BSD on : CH9.4 CH9.31B
Procedure
Run
DC330
[009-153].
Is H displayed?
Y
N
Check installation status of the DRUM.
