Following an error on a B200 Pixma MG5250, I tried to replace the print head. This replacement does not allow me to repair the printer: (((( Disclovers reimbursed me 50% of the purchase against dismissal of the head: what seems correct! Despite numerous attempts, the printer seems unrecoverable: I still believe in a planned obsolescence because the printer did not yield any sign of weakness before breaking down !!!
