Much of what happens on modern printers is determined in software, but there's still plenty that can physically go wrong with them. One Lifehacker reader got their office printer working again using nothing more than a little Blu Tack.

Jon wrote in to tell us of how Blu Tack saved the day for one printer:
A client's printer was giving an "ADF door open" error, due to a small plastic clip on the printer ADF (automatic document feeder) door being broken (I suspect they had somehow 'yanked' the ADF door open, thus breaking the plastic bit). This meant that a receptor in the ADF was not registering when the ADF door was closed. Solution? Jam up the receptor with a bit of Blu Tack -- message disappeared straight away.
Jon's account reminded me of how I kept an ancient printer working for quite a few years by resting a heavy weight on the serial cable connection. There was a damaged pin somewhere inside the connector, but the weight managed to render it workable again.
What weird fixes have you used to keep printers functioning? Share in the comments. Thanks Jon!
