Paper Take-up from Lift 1
1. After Lift 1 has completed its lifting motion, Paper Take-up Roller is
driven to take up and feed a sheet of paper until the paper blocks
Paper Standby Position Sensor. This serves as the standby position
of the paper.

2. When a Paper Take-Up signal is received from the printer, the
Separator/Feed Rollers and Paper Take-up Roller 1 are driven to
transport the paper up to Registration Sensor. After the Registration
Sensor has been blocked, the paper is transported a little further to
reach the Vertical Transport Roller, plus form a registration loop,
before being brought to a stop.

3. The Vertical Transport Roller is driven to transport the paper to the
printer. When the trailing edge of the paper being transported by the
Vertical Transport Roller unblocks Paper Standby Position Sensor,
the subsequent sheet of paper is transported to the standby position
and the LCC waits for the next Paper Take-Up signal to be received.
4. Registration Clutch is deenergized a given period of time after the
trailing edge of the paper being taken up has unblocked Registration
Sensor. The next Paper Take-Up signal is transmitted after the
timer, which is started as the Vertical Transport Roller starts moving
for the preceding sheet of paper, has run out.
5. The steps from 2 to 4 are repeated to transport paper from Lift 1.
