C0520 Abnormally high fus-
ing temperature
• The Main Motor (M1) Lock signal remains HIGH for a
continuous 1-sec. period at any time 1 sec. after the
Main Motor has started turning.
• The Fusing Cooling Fan Motor (M3) Lock signal
remains HIGH for a continuous 1-sec. period while the
Fusing Cooling Fan Motor is turning at full speed or
decelerated speed.
• The Power Supply Cooling Fan Motor (M4) Lock signal remains HIGH for a continuous 1-sec. period while
the Pow er Supply Cooling Fan Motor Remote signal
remains ON (for full-speed rotation) or OFF (for decelerated-speed rotation).
• The Toner Bottle Home P osition Sensor (PC7) outputs
a HIGH signal for a continuous 3.5-sec. period while
the Toner Bottle is turning.
• The Toner Bottle Home P osition Sensor (PC7) outputs
a LOW signal f or a continuous 2-sec. period while the
Toner Bottle is turning.
• The image transfer voltage remains more than 100 V
for a continuous given period of time while the PC
Drum remains stationary.
• An incorrect setting is made of Adjust 11.
Roller more than 35 sec. to reach 100 °C since the
start of a warm-up cycle.
• It takes the surface temperature of the Left Fusing
Roller more than 25 sec. to reach 140 °C after it has
reached 100 °C.
• It takes more than 20 sec. for the warm-up cycle to be
completed after the surface temperature of the Left
Fusing Roller has reached 140 °C.
• The surface temperature of the Left Fusing Roller
remains lower than 120 °C for a given period of time
while the copier is in a standby state.
• The surface temperature of the Left Fusing Roller
remains lower than 120 °C for a given period of time
during a print cycle.
The surface temperature of the Left Fusing Roller
remains higher than 240 °C for a given period of time.

C0650 Faulty Scanner Home
Position Sensor
C0B60 Bin Switching Motor
malfunction
• The Scanner Home Position Sensor (PC6) does not
go from HIGH to LOW when the Scanner Motor (M5)
is energized for a given number of steps after the
sequence to bring the Scanner back to its home position has been started at the end of a scan motion and
during re-shading.
• The Scanner Home Position Sensor (PC6) does not
go from LOW to HIGH when the Scanner Motor (M5)
is energized for a given number of steps after a scan
motion has been started at the end of a Scanner
Home Position Sensor home check scan motion and
during re-shading.
If the Upper Home Position Sensor is LOW during an initial operation:
• The Lower Home Position Sensor (PC33) is LOW
when the Bin Switching Motor (M1) starts turning forward.
• If the Lower Home Position Sensor (PC33) does not
go LOW at a time 2.5 sec. after the Bin Switching
Motor (M1) has started turning forward, the Bin
Switching Motor is kept deenergized for a given
period of time and then energized again to turn backward. The Upper Home Position Sensor (PC32) does
not go LOW after the motor has started turning backward.
• The Upper Home Position Sensor (PC32) does not go
HIGH at a time 1 sec. after the Bin Switching Motor
(M1) has started turning forward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Upper Home Position Sensor (PC32)
does not go LOW at a time 2.5 sec. after the motor
has started turning backward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Lower Home Position Sensor (PC33)
does not go HIGH at a time 1 sec. after the motor has
started turning backward.
If the Lower Home Position Sensor is LOW during an initial operation:
• The Upper Home Position Sensor (PC32) does not go
LOW at a time 2.5 sec. after the Bin Switching Motor
(M1) has started turning backward.
• The Lower Home Position Sensor (PC33) does not go
HIGH at a time 1 sec. after the Bin Switching Motor
(M1) has started turning backward.
