Detection timing
• The motor lock signal remains HIGH for a given period of
consecutive time while the media feed motor is being
rotated.
• The motor lock signal remains HIGH for a given period of
consecutive time while the media feed motor is being
rotated.
• The IDC sensor does not come into the condition where
the level detection is available (retracted position = IDC
sensor shutter is open) within a given period of time after
the 2nd transfer release solenoid has turned ON.
• The IDC sensor does not come into the condition where
the level detection is not available (pressed position = IDC
sensor shutter is closed) within a given period of time after
the 2nd transfer release solenoid has turned ON.
• The 1st transfer release sensor is not activated (retracted
position) within a given period of time after the 1st transfer
release solenoid has turned ON.
• The 1st transfer release sensor is not deactivated (pressed
position) within a given period of time after the 1st transfer
release solenoid has turned ON.
• The polygon motor does not rotate evenly even after the
lapse of a given period of time after it has been started.
• The motor lock signal remains HIGH for a given period of
consecutive time while the polygon motor is being rotated.
• The SOS signal is not detected within a given period of
time after the output of the laser has been started.
• The thermistor /1 does not detect the specified tempera-
ture and the warm-up cycle is not completed even after the
lapse of a given period of time after the cycle has been
started.
• The temperature detected by the thermistor/1 does not
reach a predetermined level even after the lapse of a given
period time after the warm-up cycle has been started.
• The difference between the temperature detected by ther-
mistor/1 and that detected by thermistor/2 exceeds a pre-
determined value.
• The temperature detected by the thermistor /1 remains
lower than the specified value for a given period of time or
longer.
• The temperature detected by the thermistor /1 remains
higher than the specified value for a given period of time or
longer.
• The heater lamp remains ON for a given period of time or
longer.
