6.5.1.6.11 Paper Near Empty Detection
A paper-near-empty condition is detected by sensing the height of Lift 1 or Lift 2. When paper is
consumed during a copy cycle, Lift 1 or 2 gradually moves up. This eventually blocks the Paper Near
Empty Sensor, at which timing the machine determines that the LCC will soon run out of paper (the
amount of paper (80 g/m
the LCD.
Since the amount of paper still available for use varies while a paper take-up sequence is in progress,
detection is made at a timing when the Paper Take-Up Roll is in the retracted position.
6.5.1.6.12 Paper Empty Detection
A paper-empty condition is detected by a reflector type photosensor, Paper Empty Sensor 1 PPS1 and
Paper Empty Sensor 2 PPS2, installed in the Paper Take-Up Unit. When a paper-empty condition is
detected, the corresponding message is displayed on the LCD.

• When Paper is Loaded
The light from the LED of Paper Empty Sensor 1 PPS1 or Paper Empty
Sensor 2 PPS2 is reflected, with which the machine determines that
there is paper in LCC.
• When No Paper is Loaded
The light from the LED of Paper Empty Sensor 1 PPS1 or Paper Empty
Sensor 2 PPS2 is not reflected, with which the machine determines that
there is no paper loaded in the LCC.
