3. OPERATION AND TIMING
The presence/absence of paper or a jam is checked in reference to the presence/absence of paper at a
specific sensor at such times as programmed in the CPU in advance.
The CLC1000 remembers the 'number of copies remaining at time of jamming' and 'copying mode' so
that the user need not reset these settings after opening the front cover for jam removal.
The CLC1000 will assume the presence of a jam if any one of the sensors is on when the power is turned
on.
If paper is left behind where there is no paper sensor (on the transfer belt for example), a jam is identified
when the paper turns on a sensor while being moved by the drive of warm-up operation.
If a jam occurs during continuous copying, copies on the delivery side with reference to the jam will be
processed normally provided that the feeding system for such copies is independent of the feeding system
used by the jammed paper.
