10. PAPER TAKE-UP SECTION
10-1. Multipurpose Tray
(1) Paper take-up mechanism
• When the Paper Take-Up Solenoid is energized, drive from the Main Motor is transmitted
to the Paper Take-Up Roll through the Paper Take-Up Clutch, turning the Paper Take-Up
Roll.
• At the same time, the Depressing Cam turns so as to raise the Paper Lifting Plate. Then,
the top sheet of paper loaded in the tray is taken up and fed into the printer.
• The actual length of paper is detected based on the period of time through which the
Paper Take-Up Switch remains actuated (or through which the paper moves past the
switch) and the system speed. It is then determined whether or not the actual length
matches the paper length specified on the controller.
(2) Double feed preventive mechanism
A fixed paper separator pad is used to prevent the second and subsequent sheets of paper
from being taken up and fed in with the first one.
