The drive of the cassette unit motor 2 (M2cu) is
used by the pick-up operation of cassette 5.
When the pick-up clutch (CL1cu, CL2cu, CL3cu)
turns ON, the appropriate pick-up roller rotates, and
the vertical path roller moves the copy paper to the
copier's vertical path roller. (The copy paper then
takes the same path as it would if picked up from the
machine's cassette.)
The cassette unit has three vertical path sensors
used to check the pick-up operation for each
cassette.
