When printing a scanned object, paper is all gray

When I scan then print, I can hardly read the form because all the background is gray or darker. It doesn't come out black letters on a white background like the original.

Whatever scanning utility you are using, set it to Black and white, not grayscale nor colour! regards, babb

How to have white background on small documents

All areas outside of the document will be black only. I don't know how you were getting white background.
If you want white background around your scanned image, a) stick the check (in this example) onto a white paper and scan the whole sheet. Ensure double detection is off. b) You can also do this in software, by cropping a larger area outside the scanned image.

There are many options to view the scanned image like Actual size or Fit or Fit vertically or Fit width. The same image will appear different in each case.

My sahara Flatbed Scanner works fine except that I cannot find how to print without a "grey:" background. What should I do to print with a clear white background? Eric Schafer. Cape Town RSA.

you will find if you reduce the dpi the scanner is scanning the pictures or documents in, that you will not get a grey background , as you describe, what it is printing is actually the paper itself, if you have it set for say 1200 dpi then reduce it to 600 dpi or even 300 dpi and you will see the difference when you print it
or only select the exact area you want to scan in the document, click preview then move the scan area selection box to exactly fit the picture you want to scan

Scanjet G4050 - Image is sometimes at an angle in PDF scan, even though paper and original text was straight. How to prevent this?


This is a flatbed scanner. Since the paper is aligned to the sides of the scanner the problem could be two things:

- The paper guides on the sides of the scanner are not accurate to the scanning path

- The scanning bar is not moving parallel to the sides of the scanner (one side is slightly ahead of the other side).

I had a similar flatbed scanner and the paper guide was off about 1/16" - so all scans were either tilted or I had to manually move the paper on the glass to correct.

HP do have directions on how to maintain your scanner -

- but it does not include any info on how to re-calibrate it. So it would appear that this is something you will have to manually correct.

Download and print out something with a grid or ruler measurement on it. This site has some examples -

Align the page normally and scan it with your scanner, print the results. Compare the scanned print to the normal page and adjust the paper accordingly on the scanner.

Once you have the new location for originals on your scanner, take some construction paper or poster board and trim out pieces to tape or glue to the glass of the scanner to form a new paper guide.

While a calibration tool would be better, this method will definitely work.

I620 scanner

Is the scanner scanning normally otherwise? Try scanning a printed matter with white background and if it is okay, then the streaking may be because of excess brightness chosen. Check if the paper movement is at constant speed. If it is smooth paper, it may slip and the same area may scanned again, appearing like a streak.

Re : CanoScan N640P/Lexmark Printing Problem.

There could be a setting in your scanner drivers to fix that. It would be under background settings.

The other thing you can do is preview the document first and select the area you want to scan. Then press the scan button again. That way the black background that isn't needed will not print.

Gray backround

Does your scanner software give the option to choose different modes...grayscale, color, black & white?? This sounds like it's scanning in grayscale....if you can change it to black & white, the background should remain white.

How do I scan colored paper and still read print? HP Scanjet 8270

First thing to try is just play with all the scan settings to see what gives you the best result - try changing resolutions, type of document, type of output document, contrast, brightness, type of scan. If this doesn't give you any better results, then one of the best ways to do this is to get some plastic sheet of the same or almost the same as the predominant colour on your forms (you can go one step further and make a multi coloured filter if you are feeling creative and your forms are all identical). The text jumps out of the page and most scanners will give you a good scan - just make sure the filter is not too thick/dark. Hope this helps :)
