Well I guess this is a place as good as others to ask about my problem. I know people here deal with photo restoration daily so they also have to know about scanning.
My problem goes like this. I was recently in the need of getting my paper photos into digital format, so I bought a Canon LIDE 220. This decision was taken after I saw that the scanners on my HP Printers don't produce the best results. While the Canon is indeed a good dedicated scanner, I encountered the same problem I was facing on the HP ones, respectively a sort of vertical pixel tear that appears on every scan, as can be seen here . This becomes apparent on 600 dpi resolutions and above, when using the Photo profile and Unsharp Mask in Canon Software.
Seeing this, I wrote a message to Canon support explaining the issue, but they just replied with a canned response. Interestingly enough, in the video they sent me, where a guy explains how scanning at higher resolutions work, you can also see they kind of tearing I'm encountering .
Don't get me wrong, this isn't a huge issue to me. I can repair the tears in Photoshop by using motion blur perpendicular to the tearing then painting it on a mask just in that place, but it's an unnecessary step that is added to my workflow of archiving the photos.
Now judging by the fact that the HP scanners also did the same thing and on that video, I am starting to deduce this is more like a sensor limitation to these type of scanners. Also, I'm inclined to send the Canon back and get an Epson V19, but I'm afraid it does the same thing.
What is also interesting is that there are always 2 tears/photo and also by measuring the distance between the pixel tears, they are always at the same distance no matter how many photos you place on the scanner bed or in what position.
What can people with more experience tell me? Is this a common occurrence? Is it a problem of cheap scanners?
