30.1.10 Scanner Failure The ADF fan is not operating.
The ADF fan operates only during a scan
process.
1. Remove the ADF rear cover and
watch the fan during a scan process.
2. Verify that the fan connection on the
ADF intermediate PCA is firmly seated.
3. If the fan does not rotate, replace the
ADF.
30.1.6 Scanner Failure This is a scanner-fan error. This fan is
located in the base of the scanner
assembly. It operates whenever the
scanner lamp is illuminated or whenever
the scanner flatbed motor is rotating. This
fan also operates during the MFP
initialization sequence.
1. During the MFP initialization
sequence, try to listen to this fan to
find out if it is operating.
2. Verify that connector CN108 on the
scanner-controller PCA is firmly
seated. Also make sure that the
connection for the fan in the base of
the scanner assembly is firmly seated.
3. If all the connectors are secure but the
fan is not operating, replace the fan.
30.1.8 Scanner Failure This is a scanner-calibration error. The
scanner might be locked, or a cable might
not be connected correctly.
During the MFP initialization sequence, the
scanner optical assembly moves from its
home position to the calibration strip. If this
movement does not occur, this error
appears.
1. Raise the ADF, and make sure that
the scanner lock is in the unlocked
position.
2. Turn on the MFP and watch to see if
the optical assembly moves. If it does
not move, remove the scanner glass
to see if anything is hindering the
optical assembly from moving.
3. Make sure that the optical-assembly
drive belt is installed correctly.
