  If your Epson printer indicates a paper jam, try the following: 1. Press the [Maintenance] button on the printer's panel. 2. If the paper jam persists, open the printer cover and remove all paper from inside the printer and the hopper. 3. Ensure there is no paper inside the printer, then load paper on the hopper and press the [Maintenance] button again. This should resolve the issue if the leading or trailing edge of the paper couldn't be detected during feeding.

  If your Epson printer displays a fatal error, follow these steps: 1. Turn the printer off, wait a few seconds, and then turn it back on. 2.

  Martin MedinaAug 7, 2025
  If your Epson printer displays a 'Paper Out' error, here's what to do: 1. If the paper tray is empty, load paper into it. 2. If the paper stopped halfway, remove the paper, ensure it is not bent, fan the paper, and load it against the edge guide. 3. Press the [Maintenance] button to clear the error. This usually happens when no paper is loaded, paper stops before the PE sensor, paper isn't aligned against the edge guide, or the PE sensor connector is disconnected.
