Changed the Cyan and Magenta cartridges now only 525PGBK and Yellow print. Cyan and Magenta are totally missing and 526 Black prints grey.!
Any ideas?

Have you run a print head clean routine?

Sorry for the delay in responding, I've been out of town for the last 10 days.
Yes, I have used the head clean routine, three times. I have not tried the deep clean as it apparently uses a lot of ink and that could make buying a new printer more economical.!
I have treated the parking / cleaning pads with an industrial thinners and this resulted in an almost perfect pattern print for the Magenta and a weak print on Cyan. The 526 Black is still grey. Now, after returning home, I find the pattern print has reverted to just Yellow and 525PGBK - Cyan and Magenta are missing as before.

Print-head may be damaged. I've had this problem on a HP desk-jet where one of the 3 colors was missing. I ordered a new print head for 15 USD (or less, don't remember exactly) from aliexpress website..
After replacing the print-head all was perfect again.

One other possible - and a long shot at that...

Try cleaning the contacts within the printer - those which make contact with the cartridges

Tape head cleaner or isopropyl alcohol and a q-tip?

As I say it’s a very long shot, and likely sluc is more on target?

I have no experience with color printers, but I do have some
experience with colored inks. Is there any chance the ink
pigments have separated from the solvent and settled in
their containers? Can they be shaken to try (probably not
successfully) to re-mix them? Better (but still not likely to
work even if it can be done, but hey...) stirred?

sluc - Thanks for the idea, although I'll need to find out how to change the print head. Is this likely to be on Canon's web site.?

trvir - Nice idea, I'll try that one, it seems simple enough, even for me.!

Jeff - I usually shake the cartridges before loading ... as regards stirring rather than shaking, I'll ask "Mish Moneypenny".!!
