[CQ] DR-7080C Scanner issue

[fatfingers73]

Morning all,

Having the same problem with a few of these. If scanning in grayscale or colour, every few sheets one comes through much lighter than the rest.

This is simplex through the ADF.

I've tried swapping every part from a good scanner (boards, lamp, CCD) but it still does it.

Any advice would be great

Happy New Year!
