I have printed from my Canon IP 3500 printer from 2 months with no problems. But suddenly today, after printing 10 pages, my printer take the paper in and pretends it is printing. But actually it wraps the paper around the exit rollers and a blank page come out of the printer. I don’t understand what’s going on with my Canon printer. Also, the green light in my printer is illuminating showing that printer is connected but actually printer is not printing anything.
