Detection timing
<When FS-527 is installed>
• The upper lower path switching sensor
(PS26) is turned neither ON nor OFF even
after the set period of time has elapsed after
the upper lower path switching motor (M6) is
turned ON.
<When FS-527 is installed>
• The tray1 path switching home sensor (PS7)
is turned neither ON nor OFF even after the
set period of time has elapsed after the
tray1 path switching motor (M8) is turned
ON.
<When FS-529 is installed>
• While the motor is rotating, the fan lock sig-
nal remains L for the set period of time.
• When the main power switch is turned ON,
malfunctioning of the non-volatile memory
on the FS control board (FSCB) is detected.
• The transfer belt retraction sensor does not
detect "switch from retraction to pressure"
within a given period time after transfer belt
retraction clutch has stared engagement.
• The transfer belt retraction sensor does not
detect "switch from pressure to retraction"
within a given period time after transfer belt
retraction clutch has stared engagement.
• When electrostatic charge output is ON,
electrostatic charge leak detection system
continues to detect leaks for a predeter-
mined period of time.
• The motor lock signal remains HIGH for a
predetermined continuous period of time
while the motor is turning.
• The motor lock signal remains LOW for a
predetermined continuous period of time
while the motor remains stationary.
• Engagement is not completed in a given
period time after the color dev. unit engaged
motor has started engagement operation.
• De-engagement is not completed in a given
period time after the color dev. unit engaged
motor has started de-engagement opera-
tion.
• The motor lock signal remains HIGH for a
predetermined continuous period of time
while the motor is turning.
