A paper empty condition in the 1st and 2nd Drawers is detected by 1st Drawer Pa-
per Empty Board PWB-E1 and 2nd Drawer Paper Empty Board PWB-E2, respec-
tively, installed on the underside of the Paper Lifiting Plate.
D
The board is provided with a reflector type photosensor. When the drawer is loaded
with paper, the photosensor is activated by the light reflected off the paper. The
copier then detects that there is paper in the drawer.
D
If no paper is loaded, the copier detects that the drawer is paper-empty and, at the
same time, the Lift-Up Motor (M13/14) starts turning backward to lower the Paper
Lifting Plate.
D
When a paper-empty condition is detected during a multi-copy cycle and if there
is another paper source (including options) loaded with paper of the same size and
in the same direction, the copier automatically selects that second paper source to
ensure an uninterrupted copy cycle (Automatic Drawer Switching).
