I have a Canon 950i which is about four years old or more. Lately it always prints poorly (black print looks yellow for example) on the first effort and the only way to get a decent print is to execute the "light cleaning" maintenece. I have also executed the "deep cleaning" but to no avail. Every time I try to make a print after the machine has gone unused for a day the print comes out as above. Why won't the printer remain "clean" and what else can I try to solve the problem?

Some times wiping the ink nozzles with a warm water damp "Lint Free" soft cloth will get the clogs out.

Are you using actual Canon cartridges or are you using third party cartridges or re-filled cartridges

Thanks donf. I am using new, original Canon cartrages.

The average life span of an inkjet printer is 3-5 years. If you got more than 3 years your money's worth. I'd replace the printer.

Well that´s kind of what I was thinking.
