Remaining paper detection

Remaining paper in the paper feed tray is detected by a combination of ON/OFF status (contact/non-contact) of contact-type remaining paper sensors (boards) CN-3 and CN-5. When the amount of remaining paper decreases, and the lift motor rotates, the remaining paper sensors CN-3 and CN-5 in the motor are turned ON/OFF.

The following 4 levels of remaining paper can be detected.
