Question about Canon PIXMA MP780 All-In-One InkJet Printer
I now have an error message on the LCD of my Pixma MP780 that says "Clear Paper Jam - Press [OK]" but there is no paper jam to be found anywhere. The print status monitor says the jam is in the transport unit at the rear of the printer. But again, there is no Jam.
Sometimes while clearing the jam (if there was one) you may leave a bit of paper left behind which obscures a sensor causing it to think there is paper still in the paper path, or sometimes even paper dust can do it. Try a bottle of compressed air and blow the path out very well. Get a bright light (good flashlight) and very throroughly eyeball the paper path for any "foreign" objects...

I had the same problem with Canon Pixma MX310. Tried turning it on and off, checked for paper bits, etc. I finally cleared it by:
1-Turning off and unplugging cable to PC.
2-Sliding cartridges to left and popping them out and popping them back in.
3-Turned it back on and error was gone and printer worked perfectly.
