If the toner supply sequence has not ended at the time the
machine operation ends, the toner supply sequence will be
resumed next time machine operation is started.
The toner supply sequence is
ended if the presence of toner is
detected for 0.7 sec or more.
The toner supply sequence is started
when the absence of toner is detected
for 0.3 sec or more.
If supply is continued without an
interruption, toner can start to overflow
(missing the timing for suspension).
If the absence of toner is detected for
90 sec, E020 will be indicated.
