I'm hoping someone can help me. I have been consistently printing with my Canon Pro-1000 for almost 3 years now. I am experiencing the following issue with many of my prints:
I have run numerous cleaning cycles, deep cleaning cycles and even system cleaning. My nozzle checks were very hit and miss. Sometimes they'd come out fine, but it wouldn't take long for them to indicate issues again. I have even since replaced the printhead, but I was shocked to find the yellow colour still not coming through properly on the nozzle check. This didn't make any sense to me, because how could a brand new printhead be clogged prior to printing anything but the head alignment sheets?
Anyway, it only took one clean to fix this issue and I generally don't have any problems with my nozzle checks. However, the magenta cast is STILL appearing and even Canon's support seem absolutely baffled by this!
This is not a consistent issue and does not occur on every print. It also seems less likely to occur on a borderless print.
Would anyone have any idea as to what the issue could be that is causing this?
Any help is much appreciated.

There are no error messages and the MacOS I am using is Ventura 13.2. I only recently updated my OS from Monterey and the issue was also present then.
I have two Canon Pro-1000s and both are connected wirelessly. My more recent Canon Pro-1000 performs perfectly, but the 3 year old one is the one experiencing the issue (even with a brand new printhead).
Whether I print using Canon's Professional Print & Layout software or Apple's own print dialog via Preview, the issue still occurs.
I use extra heavyweight fine art paper and pro luster paper. The issue does seem to occur much less on the pro luster paper but it is still occasionally present.

Check and see if the CO cartridge might be contaminated.

How can I tell if the CO cartridge is contaminated?
I replaced the CO cartridge and printed a perfect nozzle check:
I managed to print 7 prints with no issues, before it returned again as pictured here:
Obviously it's less noticeable above, but that's probably due to the colour being a very pale yellow / beige

I wonder if it's not so much a magenta cast in the upper portion, but a lack of green. Though wouldn't know why green wouldn't get printed to that area when it works in other areas.

So this is interesting... The first time I've ever seen it banded like this at the top. Does this bring us any closer to a solution?

As an aid in possible debugging run a nozzle check immediately after you get a strange printout.
I don't own the Pro-1000 and am not a printer expert, but I have seen posts where folks reported contamination of the CO by cross-leakage in the head.

Will give it a shot when the issue next appears. In the meantime I'm testing 'unidirectional printing' as Canon suggests that as a troubleshooting tip. Will see if this makes any difference.

I don't want to jinx it, but unidirectional printing seems to have done the trick. Makes me wonder if there's an issue with the head alignment and perhaps I should reset this again.
