I apparently screwed something up when I pulled a sheet out while printing. Now my Pixma G7020 freezes after every print job is completed. The screen shows that it thinks it's still printing. And the document that was just printed shows "printing" in the queue as well, preventing anything else to be printed. I have to delete the doc, then unplug the printer to reset it every time. Is there a solution to reset the printer without having to delete it and reinstall? If not, I try that.
From your description, I wonder whether you've somehow damaged a sensor in the printer? When you pulled a sheet of paper out, did it tear? Are you sure you retrieved all the bits?
Your printer probably has a sensor which detects when the tail edge of the paper leaves the mechanism. The printer uses this signal to register that the print job is complete. If it's not firing, the printer won't know it's finished and you'll get the symptom you describe.
What form that sensor takes in your printer, I'm not sure. Look to see if there's a plastic finger dangling in the path of the paper at the output point. I'm guessing there might be a sliver of paper stuck in it. Or it might not be swinging freely, or might be out of position, maybe off its hinge. Or missing altogether. Take a look and see if you can work it out. It might be a simple repair.
Win 10. I found a tech support # on Google. Not sure why it doesn't appear anywhere on their website. Anyway, they were very helpful in instructing me how to quickly uninstall and reinstall the drivers. Solved the problem.
