Detection timing
• The motor lock signal remains HIGH for a
predetermined continuous period of time
while the motor remains stationary.
• The motor lock signal remains LOW for a
predetermined continuous period of time
while the motor remains stationary.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• 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.
• The fan lock signal remains HIGH for a pre-
determined continuous period of time while
the motor remains stationary.
• Image data is not input from the image pro-
cessing board (IPB) to the printer control
board (PRCB).
• 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.
