I have an HP Photosmart C4780 printer which jams everytime I try to print a 4x6 photo. When I first execute the Print operation via the Windows Live Photo Gallery software, a sheet is advanced part way and it sounds like the printing begins, but the photo paper does not advance after that. When the printer finishes its processing, the "paper jam..." message appears in the display. Notes: (1) Nothing is printed on the photo paper, (2) Letter size paper goes through the printer without any problem, (3) I ran the HP Printer/Scan Doctor software and all systems show as being operational.
