HP T3500 desinjet continues printing without paper. It just sits printing and dumping ink in the paper path. You can;t really see it in the photo but it is in the part right before the paper star wheel assebly.

Symptoms would suggest that the Top Of Form sensor is defective. You would be best served by finding a service manual for the product and using the diagnostics to test all the sensors.

The oops sensor is in the paper path near the right edge. Get a good flashlight and look at the slot where the paper enters.
