Does anyone have any experience on this?, we have a 2 year old 1107ex (Done 5m) that we've looked after from new. Whenever the customer is doing A3 duplex runs, (about 80% of there work) they are getting the rear corner folded over (dog ear on lead edge) and paper skewed on the second side.
Its fine single sided and only does it maybe 1 in a 100 on duplex but it's getting to be more and more often and neither myself or the other engineer that looks after it can pin-point the cause.
We've have the duplex out and stripped down on several occasions but everything seems clean and in good order with no wear to guides / mylars etc.
Any help much appreciated!!
