Today I get an error E3 on a Canon printer MP140 series. At the time turned on, the printer looks to work but eventually the printer stops with an error code E3, and paper jam warning appears on the computer monitor.
I am trying to check the condition of the printer paper tray and looks fine. But when I checked more closely, I found a screw stuck in the bottom of the paper tray. I take the screw out and then I operate the printer. Tada…, the printer just works fine.. 🙂
To prevent the error appears again, there is a good idea to always close the paper tray your printer when your printer is not in use.
