If the iR 2425 curls heavy paper, the manual instructs you to adjust the COPIER > OPTION > BODY > CURL setting from 0 to 2 . This slows down the delivery motor slightly.

For the latest firmware and software to ensure hardware compatibility, visit the official Canon Europe Support Page or Canon Asia Support .

Whether you are dealing with a paper jam issue or board replacement, this should have what you need. Hope this saves someone a headache. Link is in the comments/replies.
