Blurred/ faded horizontal line (only on certain colours) on Canon iX6850

[kakafoni]

I'm having the exact same problem! It looks like it's at approximately the same spot of the page as in the original post, about an inch from the bottom. The lines always appear at the exact same spot and always looks the same, the consistency is quite striking actually! Looks like som type of misalignment, in the greens you can clearly see cyan and yellow dots. The media setting is "Hagaki A" print quality is "high"

The paper is an A3 308 gsm matte photo paper. I'm aware that it's a little heavier than what's recommended for the printer, is it the likely culprit? The print looks perfect otherwise, the printer has no problem feeding the paper, and no strange "scraping" sounds afaict.

What I've tried so far:
* Changing ink dry waiting time to long
* Align heads manually (test page looks fine)
* Activating "quiet mode"
* Deep cleaning nozzles
* Selected "prevent paper abrasion"
* Changing cartridges
* Changing orientation of the paper

The lines do disappear when:
* Changing to regular office paper
* Printing on the back of the paper (makes the image a bit blurry overall, so maybe the lines are masked in the process)

Did you try another quality setting ? The dot gain/inkspread is wider on normal-uncoated paper (or the back of your photo paper) than on coated surfaces

Welcome to the forum, kakafoni.

First, you provided an excellent history of what you have tried, what worked and what did not work!

Second, I think you answered your own question - it is probably the paper. Not only is the gsm of the paper important but also it's other physical characteristics such as surface properties and stiffness.

In addition to trying @Ink stained Fingers recommendation, consider trying a different Media setting besides Hagaki A.

In the end, the solution may be using a different paper that is within the capabilities of your printer.

Wow, thanks for the fast replies! I tried out printing on the same heavy paper, but A4 size, to save some paper (these are Hahnemühle papers so this is bankrupting me, haha!). The lines became less prominent just by changing the paper size, and changing the media setting to "matte photo paper" made them disappear completely!

Keeping my fingers crossed they don't reappear when going back to A3. Got to adjust the colors before trying that out.

They look like tractor wheels to me, suggesting the paper type is too thick for the printer…

Changing the media to "photo paper matte" did the trick, thank you guys so much!

Not sure why it works though. I usually use Hagaki A for illustrations with bright colors on heavy matte paper, i find that it produces vivid colors "out of the box". Does the "photo paper matte" profile print the ink more "densely" or something?

To be clear, the lines are horizontal. Tractor wheels would produce vertical lines, no?

Take a look at this thread, especially posts #9 and #10.
