Code Description
*: model equipped with DADF-Q1 (outside Japan, iR7105/7095; inside Japan: iR7105/7095/7086).
**: model equipped with DADF-M1 (outside Japan: iR7086).
E020 The developing assembly is out of toner. The buffer motor rotation is faulty. The toner feed
motor (sub hopper) rotation is faulty.
After correcting the fault, be sure to reset the error. (COPIER>FUNCTION>CLEAR>ERR)
0001 The absence of toner inside the developing assembly is detected of 120 sec or
more even
when toner supply operation has been executed for the assembly.
0002 The absence of toner in the buffer is detected for 60 sec even after toner supply
operation for the buffer has been executed and when there is toner inside the
hopper.
0003 The absence of toner inside the buffer is detected for 210 sec or more even
when there is
toner inside the sub hopper and after toner supply operation of that buffer
following the
replacement of the toner bottle.
0004 The absence of toner inside he buffer is detected for 150 sec or more even
when there is
toner inside the buffer and after toner supply operation has been executed for
the buffer
following the replacement of the toner bottle.
0005 When installation mode (COPIER>FUNCTION>INSTALL>TONER-S) is
executed, the
developing assembly inside toner sensor does not detect the presence of toner.
0006 When installation mode (COPIER>FUNCTION>INSTALL>TONER-S) is
executed, the
developing assembly inside toner sensor detects the presence of toner, but it
does not
detect the presence for 600 sec or more thereafter.
0007 When installing mode (COVER>FUNCTION>INSTALL>TONER-S) is
executed, the
buffer inside toner sensor does not detect the presence of toner for 60 sec or
more.
0008 When the toner feed motor (sub hopper) is driven, a fault is detected for 3 sec
or more
for the motor.
0009 There is a fault in the rotation of the buffer motor.
0010 The power has been turned off and then on without resetting the error.
E025 The toner bottle motor rotation is faulty.
0000 A toner bottle motor error (over-current) is detected for 10 sec for a second
time.
MEMO:
The 1st detection of the error will cause the machine to indicate the message
"Shake and
Replace the Toner Container."
0001 The toner bottle motor is not connected.
E032 The copy data controller/NE controller counter fails to operate.

(sub hopper; CL23), buffer
inside toner sensor (TS1), buffer inside toner lower limit
sensor (TS2).
Disconnect and then connect the connector (J504) of the DC
controller PCB. Replace
the developing assembly inside toner sensor (TS3).
Disconnect and connect the connector (J504, J511) of the DC
controller PCB. Replace
thetoner
transport motor (sub hopper; M22), toner transport clutch
(sub hopper; CL23), buffer
inside toner sensor (TS1).
Disconnect and connect the connector (J511) of the DC
controller PCB. Replace the
toner feed motor (sub hopper; M22).
Disconnect and then connect the connector (J504) of the DC
controller PCB. Replace
the buffer motor (M18).
Reset the error.
(COPIER>FUNCTION>CLEAR>ERR)
Disconnect and then connect J512 of the DC controller PCB.
