I bought this Pixma for use on a small office network - big mistake. Canon tech support said that they do not provide help for using this model on a network and that it was not designed for use on a network to begin with. Gotcha!My problems began with a MultiPass F80 - a predecessor to the Pixma 780, when I had a paper jam. Needing a multifunction immediately I bought the Pixma directly from Canon. This was in February and the Multipass is still in the shop for repairs.The first Pixma 780 sent by Canon didn't work - a problem with the ribbon carriage. Neither did the second one - same problem. The third one finally worked, but now I found out that it is not supposed to work with small office networks.Buyer beware.
