Since the motor would normally keep trying to push the ink tray one direction, causing a nasty clicking sound, we installed a kill switch that the tray flicks as it passes which turns off the motor.<\/p>\n<p>3) The ink tray knocks over part of the old printer&#8217;s power supply casing which is tied to a string, which is in turn tied to a lever. When the casing drops it pulls on the string with enough force to throw the lever.<\/p>\n<p>4) The lever starts some gears in motion that drops the paper tray on the printer.<\/p>\n<p>5) The paper tray is attached by a string which is tied to a camera lens. When the tray drops it pulls the lens&#8217; zoom.<\/p>\n<p>6) That lens has a small arm that extends and retracts when manipulated. We attached to wire leads to that arm, causing another circuit to be closed or opened depending on the lens&#8217; state. When the string pulls the arm is retracted and the circuit closed, causing the scanner&#8217;s light bar to start moving.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here&#8217;s a video of our machine operating!
