Curl Correction Mechanism
This machine provides a curl reduction mechanism on the fusing exit.
Curling is reduced by bending in the reverse direction of the curl created at the fuser nip and forcibly adding resilience using the fusing exit roller [B], fuser exit driven roller [C], and fusing junction gate [A], located at the fuser nip exit.
The fusing junction gate is retracted for duplex printing/thick paper to prevent image smearing.
Drive
The fusing junction gate [C] is rotated via the arm [B] by turning ON the fusing exit drive solenoid [A] located on the main machine side.
When the solenoid is ON, the fusing junction gate is at no curl correction position.
Fusing
When the solenoid is OFF, it is put in the continuous curl correction position by spring [A].
Availability of curl correction by print mode
For duplex printing, or using thick paper, the fusing junction gate is retracted to prevent image smearing.

Fusing
SP1-907-096 (Operation Setting: Fusing Exit SOL Setting)
By changing SP1-907-096, the curl correction mechanism can be enabled regardless of the paper setting.
If the fusing exit drive solenoid is ON, the curl correction function is OFF. If the fusing exit drive solenoid is OFF, the curl correction function is ON.
SP value | Curl Correction | |
Tray | Bypass | |
0 | Normal Operation | |
1 | Normal Operation | Always OFF |
2 | Always OFF | Normal Operation |
3 | Always OFF | Always OFF |
4 | Normal Operation | Always ON |
5 | Always ON | Normal Operation |
6 | Always ON | Always ON |
For duplex printing, or printing to 1-bin tray, always no curl correction regardless of the SP setting, because the fusing junction gate would interfere with the transfer path.
