Detection timing
• TCR sensor automatic adjustment does not
function properly, failing to adjust to an
appropriate value.
• Alarm signals for a TCR sensor are
detected more than the predetermined num-
ber of times.
This detection is used for detecting discon-
nection of TCR sensor connector.
• Contact the responsible people of KMBT
before taking some countermeasures.
• The status with the new unit is not cleared
after the new drum unit is set.
• With the fusing roller being retracted, the
pulse of the encoder sensor does not
change even after the specified period of
time has passed after the fusing pressure
roller retraction motor started rotating.
• With the fusing roller being pressed, the
encoder pulse sensor does not change even
after the specified period of time has passed
after the fusing pressure roller retraction
motor started rotating.
• With the pressure roller being pressed, the
fusing pressure roller home sensor did not
turn ON (pressed) even after the fusing
pressure roller retraction sensor counted up
the specified number of pulse after the fus-
ing pressure roller retraction motor started
rotating.
• 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 motor lock signal remains HIGH for
a predetermined continuous period of time
while the motor remains stationary.
