Remaining paper/paper end detection
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.
Remaining paper | 100% | 70% | 30% | 10% |
CN-3 | OFF | ON | ON | OFF |
CN-5 | OFF | OFF | ON | ON |
Control panel display | 4 bars | 3 bars | 2 bars | 1 bar |
Paper end detection
When there is no more paper in the paper feed tray, the paper end feeler turns ON the paper end sensor (the sensor is unblocked).
