Remaining paper detection
Detection of paper remaining in the paper feed tray is performed by a combination of ON/OFF (contact/non-contact) status of contact-type remaining detection plates (printed circuits) CN-3, CN-5.
When the amount of remaining paper decreases, and the tray 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:
Amount remaining | 100% | 70% | 30% | 10% |
|---|---|---|---|---|
CN-3 | OFF | ON | ON | OFF |
CN-5 | OFF | OFF | ON | ON |
Control panel remaining paper display | 4 bars | 3 bars | 2 bars | 1 bar |
Paper end detection
When the paper feed tray is empty, the paper end sensor switches ON (unblocked) due to the end feeler.
