[Misc] Bad Scans on SHARP MX-2600N

[ColdFireHunter]

Hello,
I have here an old SHARP MX-2600N, and it prints perfectly but scans and copies are light and have streaks.
The mirrors, glass, and lens were also cleaned.
I tried recalibrating the game and the colors from the service menu but it has no visible effect. The calibration was done using an SIT Chart and using the procedure from the service manual.
My guess is a bad CCD or Scanner Control PCB.
Maybe somebody has an idea what the problem could be.
I really appreciate any help you can provide.

I'm guessing CCD. Have you tried scanning off of glass?? Example would help.

In sim 46 there is exposure adjustments for say auto 1,auto2,docfeed,scans ect. Many individual things you can adjust without affecting the other modes. Take a look into that.
