Paper Take-Up Mechanism
The paper take-up mechanism takes up a sheet of paper from the
paper stack on each lift and feeds it to the vertical transport roller.
A paper take-up sequence occurs when drive from LCC Transport
Motor HMOT transmits through take-up clutch 1/2 P1CL/P2CL to
paper take-up roll 1/2. When lift 1 runs out of paper, paper feeds
from lift 2.
A roll with a torque limiter prevents double feed of the last two
sheets of paper. The roll is mounted beneath paper take-up roll 1 of
lift 1.
Paper take-up roll 1 is active when paper is fed from lift 1.
Both paper take-up roll 1 and 2 activate to perform the paper take-up
sequence when paper feeds from lift 2. During this sequence, paper
empty sensor 1 PPS1 detects proper feed of paper through take-up
roll 1.
The sheet of paper taken from lift 1/2 temporarily stops at the paper
standby position sensor to minimize variations in the position of the
leading edge of the paper. Separator clutch BCL transmits drive to
the separator roll which moves the sheet of paper to the vertical
transport section.
