917.00 Problem with transfer
-- transfer servo start
error
Problem with transfer --
transfer servo start error
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,
replace the cable harness.
If there is continuity,
replace the HVPS. If the
problem continues, replace
the system board.
