C300i - Color Cast on Scans

[qbert69]

Normally i don`t use bleed removal, but for test purposes on this i did, and nothing changed.

YIKES!!!...all MAGENTA?! ...were you trying to do a color substitution/color replacement test??? Looks like the M component of a C-M-Y Separation!!!...but you're just scanning and not printing?!

Yes, printing is all fine. It only appears on scans.

Color cast scanned image is showing a heavy magenta component where there should be none!!! The only "real" color components in the scan should be Red, Green & Blue, since the CMY is not introduced into the equation until print processing!!!

Hi everyone,

i have a problem withy my scans having a magenta color cast. This behavior occurs randomly, maybe once out of 10 scans.
The whole document will have the color cast, it doesn`t matter how many pages, or which settings (resolution e.g.)

I attached two PDFs with one having the cast and one scanned normally as it should be:

Attachment 45906

Attachment 45905

Scanner: DF-714 DualScan
Firmware: AA2J0Y0-0100-G00-7B(00) - Function Version: 1.0

Settings are alle pretty much standard. No additional software installed.

7B firmware should be at Function Version: 2.0
I would try later special FW just for a good measure.
Strange problem. Don't think you can resolve it yourself even with great advices from techs here especially so intermittent and from both DF and glass. Claim it to KM dealership. Let us know.
Good luck.

Were you able to get a sample from him? He just sent me one & it looks like a color substitution/ replacement!!!

Green is the direct complement of magenta...direct opposite on the color wheel....green ccd component missing...not being processed!!!

Would be great if someone could provide me a newer firmware to install.

When i can`t solve the problem i`ll call the KM dealer.

I think the chances are pretty high, that this is a software problem? No?

I would check & re-seat all electrical connectors pertaining to the scanner connection!...that is, if you're a tech! Otherwise call a local tech!
