I get a black streak that is 1/8 to 1/4 inch wide on the back side of the sheet that I am printing, in the same place each time it happens. Is this caused by the print head and why is it on the back side of the paper?
Hi,
it is not directly coming from the head. Probably you are printing your photos without borders. This means that the printer prints slightly beyond he paper. As a consequence is sprays ink on the mechanics and after a while it starts to smear on the back of the paper.
This phenomenon is even mentioned in the printer manual (kind of caution when selecting borderless printing).
There is a menu item in the printer utilities that lets you clean the printer mechanics with a folded paper. I tried this, but it helps only little.
I have the same effect on a pixma IP 4500 , and I live with it.

Got the same problem. If I print a bunch of pages, eventually it goes away, but an hour later the annoying black streak will be on the back of the page. If I know I'm going to print something important, I'll do a "bottom cleaning" and then print immediately after. This will remedy the problem temporarily. I'm considering junking the thing.
I have the same problem. just started. tried cleaning the thing but it comes back. seems worse when using fast printing option. don't canon have a fix for it?
I get this black streak on the back of the paper at random times, but very often -- at least one in 6 pages. It's approximately 1/4inch wide and starts almost 4 5/8 inches from the left edge. Sometimes it's a faint smudge, other times it nearly soaks through the other side. Bottom cleaning has no effect. I just cleaned the bottom 4 times, and the very next page had a severe streak.
Same problem here, replaced the black print cartridges because I thought they could be leaking, didn't fix the problem.
We have three Pixma i4300s and one Pixma ip4200 at work, and I have a i4300 at home. At work ALL of the machines have started doing this, with one of them actually SPRAYING black ink out a foot! At home--where I've only used about two sets of ink the whole time I've owned it, I've started having the same problem.
This is some sort of design flaw, and I think it's crazy that we should "live with it," given the high cost of the ink. It's ridiculous.
I am also having the same problem. I have tried changing the ink and doing the bottom plate cleaner thing but have cannot solve the problem.
Can anyone help?
