Bizhub C220 jams in heater

[sufs]

We have several Bizhub C220 in different environments, who also have been sold on very different times. All of them has suddenly started to jam (within a week of eachother), and the paper stops in the heater area.

Any idea of what this could be?

Cheers,

We have not received the modification parts yet, so I can't say if they solve the problem.

Thank you. Seems like my problem. I also noticed waterdrops on several of the papers.
