If I leave it open, it prints. As I told their specialist a few minutes ago, this is like buying a car, but the engine won't run unless you leave the door open.</P> Mon, 28 Nov 2022 21:34:26 GMT https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/canon-pixma-tr8620-displaying-error-code-1240/m-p/395655#M60314 AlMcKegg 2022-11-28T21:34:26Z
