My 948 ADF has started eating pages.   If I put 5 pages in to scan, 4 will come out (with wrinkle marks) and the 5th will stay in the ADF, wrapped around the rollers.  There is no error message, so the first time this happened it was a bit of a mystery, because all you could see was the very edge of the paper on the roller.

Any idea of how to fix this, if at all?  The printer just went out of warranty, of course.
