Deeply disappointed in this Canon product (Pixma MG555). Totally unclear why, after 2 years, it should say 'Type of Pinter Head Incorrect', and freeze up - right when I am on a journalistic deadline and urgently needed to print somethng. I followed the instructions about relocating the head, which were totally unclear; there is no locking lever on the side, in fact it's a tray that slides out from the front. I performed this messy, awkward, finger-pinching operation 4 times before the printer worked again. Then it packed up once again, displaying the same message. I spent a further hour this morning trying to fix it, wasting valuable working time, until it jammed up altogether. The printer is now in the rubbish bin - and I'm left with a pile of expensive ink, which I had just bought. Off to Currys now to buy a new printer - and it definitely will NOT be a Canon. Why Canon can make super cameras, and such awful, noisy, lousy, unreliable printers, is beyond me.
