How do I change the ink cartridge on my canon pixma iP90v printer.

remove the old cartage top side whcih is very small on the top side of toner and put it in new cartridge it will start work. chers

Remove the cartridges and press the end with the ink sponges onto a paper towel. If you see ink on the towel, insert the cartridges and run the cleaning 3-7 times. This will use up some ink, but is the only way to resolve this issue. If you continue to see improvement in the prints, continue to clean until quality is acceptable.

You can't. Canon recommends that you take the printer in for service.

Not all the ink that leaves the ink-cartridge gets jetted onto the paper; some of it is "wasted", and goes into the "absorber".

So, the software inside the Canon printer has mathematically predicted, given the number of pages you have printed, and the number of times that you've turned the printer off, that, statistically-speaking, the "waste ink absorber" is almost full.

Take the printer to a qualified printer technician, for replacement of the absorber, and to "reset" the electronics to "zero pages printed".

this error mostly occurs when the printhead is starting to go bad.
