Canon iP7200 colour print problem - how to resolve?

[kr236rk]

Hi,

My printer started printing pink this evening so one or more of the colour heads is wrong. I checked the inks, did several head cleans + a deep head clean, no difference. Then I printed a head alignment: there seems to be a lot of it missing at 'B' but there's no picture to compare it with, so I don't know.

Can anyone help please? - am right in the middle of a print project :-o

Thanks,

Ric

This could be a bad ink cartridge. Try another cartridge see if that fixes it. Check the expire dates on the back of the Inks that you purchase make sure they
are good for a at least a year.

You could be right Dave! Am writing to the supplier.

The test printout showed three tones of cyan, dark, medium & light - with the lightest blue fading away into nothing. How do printers do these tones please: is there ink mixing going on, like mixing tiny bits of black to the cyan to deepen it please? The cyan was working great till I replaced the red, yellow and a black, now it's dreadful.

Many thanks - I was thinking 'ink' too!

How an inkjet printer works is complicated but you wanted to know video the link below.

i've had good luck with calling the Canon tech support... may be best esp if you installed a new magenta cartridge. I had one Canon that they diagnosed as an issue that rendered it un-fixable... they offered a good discount for a replacement printer.

Thanks to all It must have been the cyan cartridge. It wasn't flagged up as empty but it basically was. Couple of hours after slotting a new cyan into the ink tray, the printer was printing normally again. Am not going to run another diagnostic print-sheet because I used up so much ink on that already - & what ain't broke don't need fixing now (fingers crossed) 😉
