010-318 Hot-Sagging Recovery RAP
BSD-ON:4.1/10.2
The Rear Thermistor detected that the machine does not recover from Hot-Sagging in time.
Initial Actions
• Power Off/On
Procedure
Check for paper in the Fuser. The Heat Roll has no paper wrapped round it.
Y
N
Remove the paper.
Check the installation of the Fuser Unit. The Fuser Unit is securely installed.
Y
N
Install the Fuser Unit securely.
Close the LH Cover and the Front Cover.
Execute Component Control [042-001 Main Motor ON]. The Main Motor can be heard.
Y
N
Go to the OF 3 (MAIN DRIVE ASSY RAP).
Check the resistance of the Rear Thermistor between P615-12 and P615-11 (BSD 10.2 Flag 3/
Flag 2). The resistance is 3k ohms or higher.
Y
N
Replace the Fuser Unit (PL 7.1).
Check the wire between J422 and J615 for an open circuit or a short circuit (BSD 10.2 Flag 3/
Flag 2). The wire between J422 and J615 conducts with less than a few ohms.
Y
N
Repair the open circuit or short circuit.
Replace the Fuser Unit (PL 7.1). If the problem persists, replace the Power Unit (PL 11.1). If
the problem persists, replace the MCU PWB (PL 11.1).
010-319 Fuser Center Thermistor Differential Amp RAP
BSD-ON:10.2
• After the Main Lamp turned On during warm up, the Control Thermistor did not detect
READY temperature within the specified time.
• After the Main Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the Sub Lamp turned On during standby, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the empty rotation started, the Control Thermistor did not detect the empty rotation
finishing temperature within the specified time.
• After the Main Lamp turned On during printing, the Control Thermistor did not detect a
specific temperature within the specified time.
• After the Sub Lamp turned On during printing, the Control Thermistor did not detect a spe-
cific temperature within the specified time.
Initial Actions
• Check the voltage supplies to the machine and to and from the LVPS
• Check the Indoor Temperature
Procedure
NOTE: Ensure that NVM location 744-004 is set to zero (0). If the problem continues, replace
the Fuser Unit (PL 7.1)
Check for paper in the Fuser. The Heat Roll has no paper wrapped round it.
Y
N
Remove the paper.
Check the installation of the Fuser Unit. The Fuser Unit is securely installed.
Y
N
Install the Fuser Unit securely.
Remove the Fuser Unit. Check the conductivity of the contact points of the Thermostat. The
contact points are connected.
Y
N
Replace the Fuser Unit (PL 7.1).
Check the resistance of the Main Lamp between P615-3 and P615-2 for an open circuit or a
short circuit (BSD 10.2 Flag 1). The resistance of the Main Lamp is 100 ohms or lower.
Y
N
Replace the Fuser Unit (PL 7.1).
Check the resistance of the Sub Lamp between P615-6 and P615-2 for an open circuit or a
short circuit (BSD 10.2 Flag 1). The resistance of the Sub Lamp is 100 ohms or lower.
Y
N
Replace the Fuser Unit (PL 7.1).
Check the resistance of the Control (Center) Thermistor between P615-5 and P615-9 (BSD
10.2 Flag 2). The resistance is 3k ohms or higher.
