Problem with transfer --
transfer servo start error
Fuser does not maintain proper
operating temperature within
steady state control.
The fuser hot roll took too long
to heat up after transitioning to
new enhanced mode within
standby control only.
The fuser hot roll fell to far
below desired temperature
while in standby control.
Description/Action Possible repair actions
1. Check HVPS.
2. Check system board.
3. Check HVPS/ input sensor
/ toner sensor cable.
4. Check the voltage at J15-3.
The voltage changes from
+24 V dc with the printer
idle to 0 V dc when the
printer runs the print test. If
the voltage is incorrect,
check the continuity of line
J15-3 in the front cable
harness to the HVPS. If
there is no continuity, then
replace the cable harness.
If there is continuity, then
replace the HVPS. See
"HVPS card assembly
4-17. If
removal" on page
the problem continues,
replace the system board.

"System card
assembly removal" on
