13-6. Paper Empty Detection
When the Drawer runs out of paper, the Actuator for the Paper Empty Sensor drops into the
cutout in the Paper Lifting Plate. This activates the Paper Empty Sensor and the copier
detects that the Drawer has run out of paper.
As noted earlier, the Paper Lifting Plate is raised at all times by the Paper Lifting Springs. To
prevent the Actuator for the Paper Empty Sensor from being caught by the paper stack
when the Drawer is slid out of the copier, it is tilted slightly. This, however, results in the
operating stroke of the Actuator becoming small, which increases the possibility of the
Actuator activating the Sensor by the flexing of a sheet of paper as it is taken up and fed in.
To prevent this false detection of a paper-empty condition, the paper empty detection is
enabled only when the Paper Take-Up Roll is in the retracted position.
