Hello,
I want to scan documents to print them later, but I'm having color and format issues.
First of all, I'm scanning a white sheet, but when I print it, it comes out with a gray background. I don't have this issue when I make a photocopy of the same document; the white background remains white.
I want to scan a document in A4 format with my Canon TS6250. The documents I want to scan are in A4 format, but my printer scans them in LTR format width-wise and A4 length-wise. This results in a vertical white band on the right side of my sheet during scanning.
When I open the file in any software, it is much larger than A4 format, and there is indeed a vertical white band on the right side. I have this formatting issue with all the software I use to open my file.
How can I define A4 format for scanning documents?
I am showing you the settings in a screenshot when I scan a white sheet.

Well, one last time:
1 - you do not test a scan with a blank page, but rather with a filled page edge to edge with a color or an image
2 - post a screenshot of the preview before scanning that you get, with a filled original, in your scanning software (so after clicking on Preview)
3 - post a screenshot of the file obtained by the scan opened in the software with which you will print
To me, the thin white strip is normal given your printer's scanning capability, slightly larger than A4. I explained these format issues to you, but apparently, you did not take them into account
The gray background is also normal because the scan result does not certainly give the value 255 to all three components (RGB) for pure white, so no ink deposit

With all that, I think I'm good,
I've never had this kind of problem so I'm very surprised, especially with the gray because I don't have this issue when I make photocopies.

My printer can scan larger than A4, I understood that, but I have the possibility to define a dotted frame that represents the size of an A4 that I can slide left or right, so even if I scan larger, I can still make it A4.

I haven't made any adjustments, no tinkering, no manipulation
This explains that
The bare minimum for a scan is a white point, a black point
Among other things, you have set the printing to fit so the software adapts your scan to the printable area of the printer
An OCR won't change anything; it only serves to recognize characters in an image to turn them into text
To tell you more, we would need your image available and analyze it in good imaging software like Photoshop.
As I mentioned, I think it's poorly scanned and that the white point is not correct.
Furthermore, the PDF saving format has its own specificities and doesn't help matters.
Aside from my framing issues that are not very visible, a scan is a scan, it's a point-by-point image of what is on the page.
If the paper is slightly less white, of a different quality, etc., or if the reflection on the glass produces an effect, it will also be in the final image.
Technically, a scan is not just the images and text on a "background"; it reproduces EVERYTHING. It's just an image of the A4, not a selection.
It may show up more in a print than in an electronic document, but that will depend on the screen displaying it.
Having a scan that only captures images and text without a background is called OCR processing.
I also have a Canon, just not the same model, and I experience this phenomenon too, always, as it's normal.
It is sometimes possible to slightly adjust the final result via settings (moire, etc.), but it will still be just an image, nothing more.

For the gray background, it's the first time I've encountered this. I've already scanned and printed before, and I've never seen this. I need to find a solution because it will consume too much ink.
I set an A4 format for the scan, and the tool makes a selection in A4, but these white bands on the sides are not normal. I've never seen this. I want my file to take up the entire page.
