It's I don't have a sledge hammer handy. Yesterday, my HP printer kept complaining about a non-existent paper jam. I went through all the steps of opening and closing doors and reaching inside, just so it would know I was being a good boy. That wasn't enough. I turned it off. I unplugged it. I opened and closed all the doors. Later in the day, it worked. I guess it forgot it was supposed to nag me.

Someday, someone is going to invent a printer that actually works.
