Overall very good, this is my third after two Canon inkjet multifunction whose excellent Pixma MP610 (which still works) followed by disappointing iP3600 (color fidelity not respected, unknown problem of MP610). Connected via USB, has struggled to get under way (padding indicator that had endured but there was nothing blocked, strange!?). No red trend observed for our part and more than 600 color copies recto / verso (automatic) performed, the level of the ink cartridges has so far not fallen, we are pleasantly surprised. The printing quality is perfect, instant dry and not soaked sheets with ink as the ink jets and more prints in the same quality in the front and back which was not the case with the MP610 (reduction inking the back ...). The only complaint we have seen récurentes repeated tasks (several times in the same page and in the same place on the horizontal) in blue prints, some claim that this comes from a fault on one of the toners that will disappear change it (?), we are puzzled and somewhat disappointed. That said we have not tried cleaning the first or second level as the Canon advocates when tasks because on one hand it is brand new (and with our inkjet That never corrected any defects) and secondly we are afraid to consume toner unnecessarily ... Otherwise it is recommended, as time gained to print 100 pages Duplex ongoing professional quality and everything dried subsequently by against the images are frozen can not rewrite over! Otherwise noise and clutter quite correct.
