010-338 Fuser On Time Failure RAP

BSD-ON: BSD 10.1 - Fusing Heat Control
• 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.

Procedure
NOTE: When this fault occurs, NVM location 744-005 is set to 1, 2, or 3, depending on the
fault. You must reset this location to 0 in order to clear the fault.
Check for paper on the Fuser. The Fuser 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 J621-6 and J621-7 for an open circuit or a
short circuit (BSD 10.1). 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 J621-2 and J621-7 for an open circuit or a
short circuit (BSD 10.1). 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 J621-5 and J621-1
10.1). There is no open circuit in the Center STS and the resistance is 3k ohms or higher.
Y N
Replace the Fuser Unit (PL 7.1).
