Error
(Error 10)
There is a problem with the laser unit.
The engine control board did not receive
a signal from the laser start-of-scan
sensor within the specified time
1.
Test the top cover and right
front cover switches for
proper operation. Power for
the laser unit is routed
through both switches
2.
Replace the laser unit.
3.

board
Image
Density Error
(Error 11)
The image density readings indicate a
problem. The engine control board
detected that the printer image density
was unusually low and attempts to raise
the density have failed.
Note
If the top cover is removed,
light can leak into the printer
and cause a auto-density
calibration sensor error.
1.
Power cycle the printer
2.
Inspect the toner cartridges.
3.
Inspect the four developer
housings. Each magnetic
roller should be evenly
coated with toner. Replace a
suspect developer assembly.
4.
Test the toner/developer
dispense motor. Replace it if
it does not run
5.
Inspect and reseat the
auto-density calibration
sensor. Ensure the senor’s
solenoid-activated cleaning
blade is in place and moves
freely.
6.
Test the auto-density
calibration sensor. If bad,
replace the auto-density
calibration sensor
7.
Replace the imaging unit
8.
Replace the engine control
board
9.
Replace the high voltage
board
