voltage checks:
If the voltages are not correct replace the engine board.
Blurred or Fuzzy Print
This can be caused by a damaged gear train or by paper slippage in
the feed roll or transfer roll. Also see Banding.
Inspect the HVPS contacts; make sure each spring-loaded contact
returns when pressed and released. Inspect the transfer roll housing
contacts for damage or contamination. Check the gear train for dam-
age, binds, or wear.
When using the 100-sheet auxiliary feeder, some blurring may occur
at the point where the feeder’s friction rollers release the paper.
Dead Machine
Possible causes: no voltage reaching the printer, LVPS failure, blown
LVPS fuse, failure of the On/Off switch or switch linkage, or a
shorted electrical component.
Check for the indicated voltages at the LVPS connection to the
engine board. If no voltages are present, remove the LVPS cover
and check fuse F1 and the power switch before replacing the LVPS.
If some voltages are present but all are not correct, disconnect all
cables except the LVPS from the engine board. POR and verify that
