I am a teacher and have a Canon TS3122 on my desk. It's been great and I've never had issues with it until this week. It was working fine and then got a paper jam. I cleared the jam, figured out the error code, and cleared the code, but ever since then, it won't print. It will scan and print, but it won't print from my computer. It's not throwing an error code. I'm not sure what else to do! Help!
