16-4. Paper Empty Detection

• A paper empty condition in the 1st and 2nd Drawers is detected by 1st Drawer Paper
Empty Sensor and 2nd Drawer Paper Empty Sensor, respectively, installed in the paper
take-up area of each drawer.
• When the drawer, with no paper loaded in it, is roughly pulled out of the copier, the Paper
Empty Lever can hit against the Paper Lifting Plate. To prevent this from occurring, the
Paper Empty Lever is tilted in the direction of drawer movement.
