BSD-ON: BSD 10.1 - Fusing Heat Control
The Rear Thermistor detected a temperature higher than the specified value.
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 the resistance of the Rear Thermistor between J621-7 and J621-3
resistance is 3k ohms or higher.
Y N
Replace the Fuser Unit (PL 7.1).
Check the Rear Thermistor wiring between
cuit ( BSD 10.1). The wire between
