Polygon Motor Error 2: OFF Timeout
SC203 B
The polygon mirror motor did not
go off within 3 s after the motor
was switched off.
• Connection between the polygon mirror
motor control board and the motor is
loose, broken, or defective
• Polygon mirror motor defective
• Polygon mirror motor control board
defective
• IPU defective
• BCU defective
Polygon Motor Error 3: XSCRDY Signal Error
SC204 B
The machine detected that
the polygon mirror motor
XSCRDY signal went
inactive :
• While an image was being
created
• During the output of a
synchronous laser
detection signal
• Switch the machine off/on (problem was
probably due to electronic noise)
• Replace the harness if cycling the machine
off/on does not solve the problem
• Polygon motor defective
• Polygon mirror motor control board defective
• IPU defective
• BCU defective
Polygon Motor Error 4: Unstable Timeout
SC205 B
The machine detected that
the polygon mirror motor
signal went inactive at
some time other than:
• While an image was
being created
• During the output of a
synchronous laser
detection signal
• Switch the machine off/on (problem was
probably due to electronic noise)
• Replace the harness if cycling the machine
off/on does not solve the problem
• Polygon motor defective
• Polygon mirror motor control board defective
• IPU defective
Synchronization Detector Error 1: LD0
SC220 B
When LD0 fired with
the polygon mirror
motor rotating at
normal speed, an
synchronous
detection signal was
not output within 250
ms. This can occur
when the machine
recovers from the
energy save mode
and there is no paper
available
• Make sure there is paper in the trays
• Cycle the machine off/on
• Harness connector of the laser synchronization
detector board is loose, broken, defective
• Laser synchronization detection board defective or
installed improperly
• LD unit defective
• IPU defective
• BCU defective
