MP 301 scanning issues

**Stormhammer** · 10-25-2018

I have a machine that a customer has that they need to scan in color on but when they scan the lower long edge is tinted red. I cleaned out the scanning unit and made sure the white strip on the underside of the glass was white. The LED array also seems to be working alright. I've never seen anything like this before. Attached is a PDF of a scan directly from the machine.

First thing I'd try is a firmware update.

Firmware levels are up to date. I don't see any mention of scanning quality issues in firmware notes.

Had this one the other day on a c5502. Edges were blue and red.

Blueish scans c5502

Why not simply tell them to choose mono scan?
Also try changing the dpi settings.

They have to have color for their multi page documents for parts schematics. Besides that, that wouldn't make the issue go away unfortunately. Gonna try replacing the scanner carriage assembly and see if that fixes it. I tried all the ribbon cables and ZIF sockets already, too. I wonder if moisture got into the CCD or something.

does the problem happen on the flatbed or adf? was there an SC code recorded?

Clean the flat cable that is connected to the bord on carriage unit.

Ambient light infiltration? Block lighting around the scanner edges or better yet, turn off lights in the room if possible. I know it's a stretch but I's seen similar problems caused by this. Good luck...
