I just received a Riso EZ 590u and upon first booting it up I got this error code: A06-403 Safety SW on Standard Feed Tray is Activated. Reset paper on Standard Feed Tray.
I'm aware that the error code can appear if the feed tray is bent or obstructed but the feed tray is perfectly straight and functioning as intended. The lower safety switch, a long metal bar running the length of the tray, is moving freely without and obstructions and is perfectly straight.
Are there any other possible solutions to this problem? Please help!
