The Machine Wrongly Detects That the Tray Is Full

Cause:

The edge of the paper is close to the paper height sensor feeler, so if it has side face-up curl, the edge of the paper may fail to go under the paper height sensor feeler and ride up on the feeler. As a result, even if the shift tray lowers, the paper height sensor will fail to turn OFF, the lowering time of the shift tray will end up exceeding 650ms, and the unit will end up detecting it is full.

Solution:

1Check if the paper width is within the range of 191 mm to 261 mm (7.5 inches to 10.3 inches).
