Pro C9200/C9210 is installed with three decurler units before the paper exit.
To de-curl the sheets, the direction of the curl (face or back) observed on the sheets and the de-curl intensity need to be specified in Advanced Settings. The upper or lower metal roller presses and delivers the sheet to the upper or lower paper path according to the settings.
A. Decurler pressure motor
B. Decurler pressure cam
C. Decurler pressure roller
The speed in which the paper passes through the decurl unit can be adjusted.
If the speed is too fast, toner may adhere to the edges of the sheets, and if too slow, wrinkles/creases may occur. Set to an optimal speed according to the stock.
The de-curl pressure motor [A] rotates the de-curler pressure cam [B] and the de-curl pressure roller [C] presses the sheet.
After the sheet passes through, the motor rotates the cam in the opposite direction for the pressure roller to release the nip.
