Problem with ADF , MP 8001

[giovanio]

Good evening, my problem is the following: suddenly, the pages scanned by the ADF are bending at a corner. I have replaced the original feed system, the output plate located after the CIS, and the piece located in the transport part, before the transport belt that the ADF has, without success. I have even replaced the numerical guide (the one on the left side of the platen glass that continues to bend the originals). I need help, I have not been able to solve this problem.
Images attached.

What do the copies look like? That is, can you see the folded corner in the copies? If you can, you have something before the slit glass causing the problem. In the turnaround guide between the skew correction roller and the slit glass. Usually it is a staple.

during the scan or copy, try to push down the the left part the ADF with the arm, , could be the worn out hinge, that not perfect match on machine

Remove and unplug the ADF from the machine, turn it upside down and shake it, maybe what you are looking for will come out.

Slimslob, both the copy and the scans come out complete, there is no omission, it's just the mistreatment that the originals suffer.

Luca72, maybe it's what you're telling me, indeed by pressing down on the left side the original moves forward without problems, I will try to get a hinge to do the tests; thanks for the suggestion.

Think of the weight of this DF.

Nothing, I took inspiration from the classic defect of MPC307's series....lol
Thanks for the feedback
