When scanning color document, blue tone is present as background shade


Have long experince with PixEdit program using Kodaks. PixEdit usually comes around it after a firmware upgrade on the scanner. Not sure about this specific model but at least OK on other models of Kodak.

Scanned image only prints in black and white


it's tricky / annoying:

you have a preview ...
you have some of the (3) images checked
but also you have some of these images selected (blue outline)

now:
when you select (I don't mean the checking) an image you'll have to set the scanning params
again - or check them ...

if you select an image, and then set the params (like "color"), your scanned image will be in color

....
also resolution is the same way ..
especially after crating preview .. it'll be set to 300 Dpi
so after seecting one for scanning - check the resolution too :)

Blurry Scanning/Copying


Are you scanning both black and white and color the same way? The ADF (automatic document feeder) uses a different scanning area than when you place the document on the scanning glass. If you open the scanner cover, look to the left of the main scanner glass to the narrow strip used for the ADF. Make sure this narrow strip is clean -- no ink or white-out or scratches. This can make your copies look dirty or smudged.

Printer turning page blue


Color copiers have four drums. black, yellow, cyan(blue) and magenta. try making a copy in single color mode. make one in all the colors mentioned above. If they all come out normal and the cyan (blue) one doesnt, this could indicate a bad cyan (blue) pcu and or developer.

Do not scan black color


When scanning small or very dark images, its a good idea to place the item to be scanned on the glass, then place 8.5x11 white paper over the top of it.
This gives the scan software "edges" that it can recognize, and once scanned the image can be "cropped" to remove the white from its border.
This has worked on all (4) the different brands I use.

Grayblue Background on scans


A color scan will give real output as it is. If the background is grey, the output will also be grey. If you select 256 Color output, there may be small change in color, as compared to the original. If you select grey output, all colors will be converted to Grey. If these files are converted to PDF, it will be same, except in ODF format.

If you select B&W you can save the file in TIFF format. Unlike grey or color, each pixel can be either black or white only. To scan in black and white you must select right brightness. By doing os you can eliminate background (technically noise) and capture foreground(data)
