Paper Take-up from Lift 2
1. When all sheets of paper have been taken up and fed in from Lift 1,
Lift 1 is placed in the top level position to serve as part of the paper
path for paper feeding from Lift 2.
2. When the trailing edge of the last sheet of paper from Lift 1 unblocks
Paper Empty Sensor 1 PPS1, both Paper Take-up Roller 1 and 2
start turning.
3. The sheet of paper is transported by driving both Paper Take-up
Roller 1 and 2 up to a point at which LCC Take-Up Sensor is
blocked.
