Query: It's a Lemon

There were problems with the unit from Day One. Ink cartridges weren't recognized and thus the unit could not operate. A call to tech support brought some replacement cartridges, but not the right ones. It required a second call and another week's wait to get the correct, working cartridges. Then the unit would not scan from the machine, although it scanned from the computer. Another 1 1/2 hours with tech support, and they couldn't get it to work, so suggested I take it in to one of their reps in another town. I thought about it overnight, and decided that I had a lemon on my hands, and shipped it back to Amazon. I had read positive reviews of this Canon product, but after this experience I decided to go with HP as a replacement.
