I PURCHASED THE PIXMA BASED ON QUALITY AND RELIABILITY OF THE CANON NAME . . . AT FIRST THE UNIT PERFORMED IMPECCABLY . . . NOW, AFTER JUST 6 MONTHS, FOR ME TO GET A CLEAN REPRODUCTION I HAVE TO CLEAN THE INK HEADS BEFORE EACH USE !!! THAT IS A NUISANCE AND A WASTE OF INK !! I WROTE TO THE MANUFACTURER AND WAS TOLD THE UNIT HEAD NEEDED TO BE REPLACED !! AFTER 6 MONTHS ???? I AM VERY DISAPPOINTED AND WILL NOT BUY ANOTHER CANON ALL-IN-ONE PRINTER !!
