We are getting conflicting information from Canon on whether the iPF780/785 printers can accept 500' rolls on a 3" core. Canon says yes, it does accept 500' rolls, AND that the specs indicate 5.9" maximum diameter paper rolls. 500' rolls are 6.5". This only amounts to an extra 0.3" at the edge of the roll, so I can see how it may work despite being a little over spec, but I'd like to confirm that someone else is using 500' rolls on the Canon iPF78x printers before we finalize our order.

T.I.A.
