In a moment of possible (alcohol fuelled) madness, in feeding in the first sheet of paper through my new Epson 3800, I somehow managed to feed the paper into the sheet feed holder on the wrong side of the width adjuster (wondered why it wouldn't stretch to A2!) Obviously, it showed a misfeed, but as I couldn't pull the paper out the way it went in, had to induce it to go the whole way through by scrolling through the buttons on the front. The A3+ sheet emerged with 2 rows of indentations, although it did print succesfully when put through the right way.
Realise this is not the recommended way to treat a printer, but is it likely to have done any long term damage to the print heads?
