I have had this multifunction machine 5 monthes and have replaced the cyan ink tank 4 times;because I keep getting a,U150 error,which means the ink tank is not recognized.

The machine will do nothing until the ink tank is replaced.

I have contacted Canon and their response is to keep replacing the ink tank.

As the machine is still under warranty,Canon sent me a new set of ink tanks via FedEx.

That is not addressing the problem,this model of machine is obviously a "Lemon".

A design error,for sure!

All reviews on this machine raved about how economical it would be, having to replace only one,color, tank at a time.

This printer uses ink everytime it is turned on,even when not printing.

What can I do about this?
