For some reason I keep getting random magenta shifts on my HP L26. Last time I got it I tried replacing both magenta heads as well as doing an alignment test. That didn't fix the issue. Wound up having to save the art in a whole new file, RIP it again and then reprint. Now I just had it happen again on a 80" wrap panel making the whole graphic look blurry. It's just magenta shifting. It would seem it's a file or RIP problem but I don't see how that's possible. Any ideas or suggestions? I've attached some pictures of what it just did.
