You should look at the Canon Forums and see what you can find there.

Good luck on finding an answer.

A month ago i had a bad surprise with my printer Canon: an error message Printhead error! Switch Off!

I switch off but when I switch on again I can't enter in the menu and so I can't neither change the Printhead; in practice I can only call the Service.

I have read too that  even if I would change the printhead the problem can stay and burn the new printhead too.

The plotter canon W6200 is already out of warranty and are years that I use only compatible ink cartridges, some of them recharged by me; I know that the service will cost me a lot of money and It wouldn't be advantageous given that the plotter is very old.

If it can help I reassume what appears on the display when I switch on: It appear Initializing and after 15 seconds CANON W6200PG then S:Ver.02.02.02 > E:Ver. 02.01 > CANON W6200PG Wait > Prepar. Print > PrintHead Error! Switch Off!!

I tried to switch off and on but nothing, I tried to take out the cartridge and the paper but nothing, I really don't know what to do to fix the plotter.

Does anyone know what I can do without calling the service?

Thank all for your help
