Excessive Curl When Printer in Thick Paper 3 Mode

A large paper curl (65mm -73mm) might develop while using “Thick Paper 3” (Paper over 165g/m²) mode. This could cause paper curling, the paper falling, or incorrect stacking.

Cause

In this machine, the position of the fusing unit entrance guide is arranged closer to the fusing roller as a countermeasure to prevent excessive curl in normal paper during duplex printing, caused by paper wrapping around the fusing roller when it enters the fusing unit.

Action

Remove the sheets one by one from the paper exit tray.
