I've got a WorkCentre 6605 with automatic document feeder and when I load a document to scan on the ADF, it will pull the first few pages just fine and then start having trouble pulling the 4th or 5th pages. They'll stall as I hear the ADF motor and wheels spinning trying to pull the page in. It'll usually end up getting the page in and then have more trouble with the next one until it eventually can't pull a page in and it stalls and gives me error code 005-110. I clear the jam and try again. If I stand over the machine and give the stalling page a push with my hand, it'll take it. I tried giving the DADF rubber wheels a cleaning with a paper towel but the problem persists. Any ideas on what else I can try before buying a new doc feeder module kit?
