Once the waste ink tank of my Canon Pixma IP 3000 after several years of use was fully or defected, I was forced to dispose of the old printer and have then bought the Pixma iP 4950. I did not understand to this day why one in a printer the waste ink tank can not just empty, but the complete, fully functional instrument must be discarded, since the exchange of the container is cumbersome and expensive than a new device. A senseless waste of resources. !!
The "new" works fine, but .... he is a cleaning freak. I'm afraid now is not only that the ink tank is filled much faster, but it annoys if you often have to wait a very long time before the printer dedicated his actual duties. It sucks.
I do not know if the compares more favorably with other manufactured article. Anyway, I'm only disappointed once.
