Docuprint CM305 df jam at duplxer

[shanelai]

The problem has arised many months. Any expert here can help urgently?

I have cleaned all 4 rollers. Noticed that the rollers are functioned together with a electric engine (i believe is something like pusher to push the paper up) hence when move it need harder because it is a bit stiff.

I've tried but still failed. Any other possible caused?

Thanks in advance.

Find the last roller the paper touches and clean it and verify it moves properly

I have a Docuprint CM305df

When attempting to print double sided, the following occurs.

After selecting '2-sided' in the print dialouge box, the document attempts to print.

The printer prints the latter of the pages first on the paper, the printer then retracts the paper back into the printer (I presume to print the rear face of the page), but then the paper gets jammed in the printer before it can print the other face of the paper.

Its wierd because it has no problems printing the first face, but as soon as it feeds back in automatically it all jams up.

I suspect it i the duplexer issue. How to repair this?

Thanks in advance.
