Detection timing
• The scanner home sensor is unable to
detect the scanner located at its home posi-
tion.
• 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 travelling distance.
• The scanner home sensor detects the scan-
ner when the scanner has moved the maxi-
mum travelling distance from the position, at
which it blocks the scanner home sensor.
• The scanner home sensor detects the scan-
ner at its home position during a period of
time that begins with the time when a pre-
scan command and a scan preparation
command are executed and ends when a
home return command is executed.
• Image data is not input from the CCD board
(CCDB) to the MFP board (MFPB).
• 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.
• When starting the scanner, verification on
reading and writing the predetermined value
for image processing ASIC on CCD board
was conducted, and verification failure was
detected.
• When MFP detects that DSC board is not
properly installed.
• When DSC bus check detects an error.
• The original transport interval becomes
shorter than the designed value due to an
original transport control error in original
reading in ADF.
