Vertical misalignment

[Celso]

Hi All, hope you can help. I own a Canon MX922. How can adjust it to print straight vertical lines? I attached a pdf with a grid pattern using excel so that you can easily see its problem. I already tried the auto alignment in the settings tool of its panel. Thank you very much.

The only thing that I can think of that would cause that type of print problem is your ink ?
Are you using 3rd party inks in your printer by any chance..

Hi The Hat, thanks.

Ink is not original. However, it is from a well known supplier.

Data maxima venia, I thought about some sort of backlash in the belts. If you look closely, the misalignment follows the very same pattern (distance) from each one. Approx. 2cm. Could be some sort o mecanical problem?

I printed another page. May be with this one is easier to identify the problem.

Thanks

The other thing you can try is to clean the timing strip both sides with window cleaner, just take it nice and slow and use a paper towel..

Here is two Pics of the timing strip..
