Hello Runanide,
I would call into the support department at 1-800-835-6100 then option #9, then #4 for parts.
The left hinge on the ADF of my 6128 MFP scanner made a loud noise while it was not being used and now does not close by like 3/4 inch. I believe I need a new hinge for it. Where might I get a hinge and instrucions on how to replace it? It still scans fine manually (without using the ADF). Thanks.
