Hello. I am getting a single light band across the end of the print from my new printer, about 1 inch from the trailing edge of the paper - the part that comes out of the printer last. So far, all my testing has been letter size, but I expect it will happen no matter what the paper size. It occurs the same size and location no matter what paper I use, different files, top or rear feed, etc. The one exception so far is that when using Canon Pro Luster paper, it does not occur. The band is only visible to the naked eye when there is a dark, solid color in that area, like blue sky in my case. When there is a lot of detail, no-one could ever see it without a microscope, but I have no doubt that it is still there. Here is a link to another post which illustrates (with some great photos of prints) the exact problem I see. I replied to that post as well, but I thought I would re-post here since more people may see it this way.

Based on some vague wording in the manual, I believe this is a limitation of the printer hardware. The manual indicates that printing within 25mm of the end of the paper "can affect the print quality or the paper feed precision". I think the safety margin here is actually more like 30mm, but that’s another discussion. Now wishing I’d bought a printer that takes roll paper…
I was attempting to find out from Canon tech support exactly what kind of degradation of the print quality we might expect, but I got nothing from them so far.
I do not believe this has anything to do with print head clogging or head height since if it did, there would be problems all over the page, not just in one band near the edge.
So, can anyone confirm my hypothesis that this is a limitation of the printer? (one that they don't really want to talk about) Is this, in fact, the print quality issue they are alluding to in the manual?
