    Hello!
    I can't get my Canon G2400 to print properly. All vertical lines printed in color are curved. When printing in black only, everything is ok. I've tried all cleaning procedures, aligning heads - automatically, and manually. Honestly, I have no idea what can I do. I'm attaching photos of example test prints.
    Any ideas why is it happening?
    Printer have about 2 years now, but it wasn't used a lot - I've refilled tanks only once through this time.
    Thanks in advance!

    I'm afraid to say that your nozzle check shows an irritating effect , the blur effect varies over the height of the printed spots , that's an indication that the printhead is nearing its end of a useful life, this effect can be seen more frequently with the pigment black ink nozzles, but I would assume you have printed quite a lot of photos or other print output with colors. You cannot clean away that effect. You may check if your unit is still under warranty with the dealer or Canon.

    I've just checked - my unit is over 2 years old, so it's not under waranty anymore :(. I have not printed lot of photos, as I said in my first post - refilled ink tanks only once. I'll try to clean timing strip again, and will let You know if it helped. Thanks!

    I thought this, too, similar to what happens with warping of Pigment Black when the nozzles are scorched. Yet it does not appear in all vertical lines, which might be a function of how the data is printed or using which colors. So, a proper cleaning of the timing strip is worth a try before posting bad news.

    There is also a slight wavy appearance to the Pigment Black latticework (use a straight edge across the top row) and a funky pinstripping effect in the Cyan swatch, leading me to think from the onset the print head is irreparably damaged.

    When done cleaning, please perform a nozzle check, scan, crop and post. Thank you.
