C300i - Color Cast on Scans

[mkonkelz]

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:

Normal.pdf

ColorCast.pdf

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

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

Are your scan settings configured for strictly B&W or Auto Color Detection???[emoji848]

If you are duplex scanning does it show on side two?

I always scan using auto color detection, so it shows on auto color. I don`t scan B&W.

I need to try this. The scans so far were only one sided.

Edit: It also appers on the original glass.

Possible CIS asssembly or cable

There ya go!!! Sounds like it is flip-flopping between b&w and color during auto detect...set to strictly b&w and see what kind of results you get!!! [emoji41][emoji1303]

Possibly a "white balance" calibration issue during auto color/b&w detect. There should be a way to adjust the sensitivity!!![emoji41][emoji1303]

Re: C300i - Color Cast on Scans

I highly doubt that is a setting issue. It looks like CIS assembly or cable. We used to see this occasionally on the 8 series.

Re: C300i - Color Cast on Scans

Okay, i just tried scanning double sided. And it only shows on the 1st side(s).
So the DualScan CIS seems not to be affected.

Edit: Also it just appered on 4 separate scans in a row, just to disapper on the 5th one, without changing anything or moving the DualScanner.

What about from the platen?

It appears from the Platen and the DF.
When scanning 2-sided from the DF it`s only on the 1st page.
When disabling Auto-Color and scanning B&W only the problem seems to disappear (not sure yet).

Sometimes it`s up to 4-5 scan jobs in a row. Sometimes everything seems normal.

Possible CCD or MFP board. Is the machine brand new? There is a security measure - press stop,1,1,4,4,C in service mode and you need to input the correct date and time at install. Sometimes if this step is missed it will give coloured backgrounding or lines through copies. Have you done this procedure?

See if there is a setting to change auto color detection sensitivity!!! I have used other scanners, not just KM that when B&W is scanned in color, there will be a slight magenta cast which is related to the green sensor array in the CCD array!!! Make sure your glass & white balance strip are CLEAN!!! Check your auto detection sensitivity!!![emoji41][emoji1303]

It is brand new (1 week old).

I will try it out, but the system got set up by the dealer (it had the right date and time configured on delivery).
