• The Scanner Home Sensor is unable to detect the
Scanner located at its home position.
• The Scanner Home Sensor is unable to detect a
Scanner even when the Scanner Motor has been
driven to move the Scanner over the maximum
traveling distance.
• The Scanner Home Sensor detects the Scanner
when the Scanner has moved 5 mm from the
position, at which it blocks the Scanner Home
Sensor.
• The Scanner Home Sensor detects the Scanner
at its home position during a period of time that
begins with the time when a prescan command
and a scan preparation command are executed
and ends when a home return command is exe-
cuted.
• The Fan Lock signal remains HIGH for a predeter-
mined continuous period of time while the Motor
remains stationary.
• Image data is not input from the Image Process-
ing Board (PWB-C) to the MFP Control Board
(PWB-MFPC).
• The adjustment value is 0 or 255 during a CCD
clamp adjustment.
• The peak value of the output data is 64 or less
during a CCD gain adjustment.
• The output from the CCD Sensor is a predeter-
mined value or less during CCD Sensor gain
adjustment.
• The average output value of the CCD Sensor with
the Scanner at its standby position is a predeter-
mined value or more at the end of a scan job.
• The controller of the MFP Control Board (PWB-
MFPC) is faulty.
• A controller hardware error is detected in the net-
