Cartridge is spoiled and damaged due to generic ink. or maybe you have immersed the part inside the water or any liquid. Sorry you have to buy another printing head

    This is interesting!, I have the same problem WRONG CARTRIDGE alarm, I would like to know just how it knows this? I could understand if they were chipped but they are not! So you are saying that substandard ink cartridges have been used and they have damaged the head in some way?
    Blocked up I can understand but wrong cartridge? Definitely a dilemma to buy a new head £60 or a new printer!

Wrong cartridge flashing light

I'm going to assume that the cartridges are correct and inserted correctly. Usuall when this happens to a new printer there is a hardware problem and you should call Canon to get a replacement. If it is not a new printer, make sure you have the correct cartridges for the printer and they are not knock offs. Knock offs do not work 100% of the time and these errors can happen. The other possibility is the cartridge has bad connectors and trying another cartridge could fix this. Again call the manufacturer for a replacement cartridge. Wish I could help you more but it is most likely a hardware issue with the cartridge or printer and Canon should fix it as long as it is under warranty.

Alarm button flashing saying wrong cartridge But i haven't touch the cartridge

Try turning the Cannon Printer off, then unplug it for awhile about 4 minutes, then plug it back in, and turn it on and see if you have the same problem, if you do call the manufacture to see what the technical representitive says to do.

Printer has stopped printing and is saying error 'wrong cartridge' We have tried compatible and original cartridges.

Cartridges won't matter on this machine, that error says that the printhead is bad. You need

Wrong cartridge

If the cartridge you bought is not compatible with that prescribed by the printer, the interconnecting ends may not match. You, therefore, need to change all wrong cartridges.
