MP C6004 Scanning with blue haze

[digicor]

i have a MP C6004 thats scanning and copying with a blue haze all over it, not sure why, it was scanning clean for the last 2 months after installed... iis there a setting to reduce this in the doc feeder?the scanner glass is clean. the optics have been cleaned....any suggestions will be appreciated

Take the glass out and shine a flashlight off of the glass at a shallow angle do the same to the mirrors. I have seen a haze buildup on the optics where they look clean until you do this test.

The only few times I've experienced a similar symptom is after someone has done an engine clear on the machine.
It was recovered by re-entering the non-defaults from the factory birth certificate - most specifically the Grey balance settings

[digicor]

grey balance setting in the scanner service mode? or where? sorry to ask, im not Infront of a machine at the moment

im changing the doc feeder, and or the optics tomorrow, nothing worked, except in copy mode i lightened up the density all the way and the blue shading went away
but, in scan mode, the blue shading is still there no matter what we did.
i checked and re adjusted 4-609-002,4-610-002,4-611=002 to no avail no matter what we put the setting on, extremes, no difference, i lifted up on the doc feeder as it fed difference,

have you tried to run sp801 (reset scanner application)? ..maybe the customer played with the numerous scanner settings(?)
it happened to me a couple of years ago on a mpc2051, I lost at least half an hour to find the combination of settings in the scanner menu, in the photos of the identity cards they all looked African pixeled

where 801? sp4?

[digicor]

I dont have a 4-801 on mp c6004

[slimslob]

where 801? sp4?

I dont have a 4-801 on mp c6004

I think it might be SP 5801 unless he is referring to Scanner SP.

[digicor]

5801 is memory all clear... we don't mess with that...
is there a scanner all clear?

have you changed anything under the scan resolution settings? i agree with everyone else about the cleaning. i have had times that i cleaned and thought i had done a good job cleaning. only to discover there was a bit more. not saying you didn't.
