Q: Hi can anyone determine why im getting a cover open error on the LCD on the face of the printer when the cover is securely closed, ive checked the manual error codes but nothing to help me any help would be much appreciated, constructive answers only please, thanks in advance
A: I wandered over to the Lexmark to find out why my X3470 would keep saying 'cover open'. The site said 'lever arm of cover sensor has fallen off'. AHA! with the scanner part taken off the top, and the grayish plastic bit unscrewed and popped off, there is a white nylon lever arm that should be seen sticking up thru a rectangular hole...roughly about 1/2" to the right of the printhead behind it. This lever arm clips onto a microswitch/sensor (the lid switch). I just popped the white nylon bit back on and presto, it's fixed. Mine had popped off and was way deep down in the bowels of the printer. This sensor is mounted on the circuit board about midway across, and you can see it if you look straight down, through the hole in the black plastic shrouding that covers the circuit board. It might be possible to snap the part back on without partial disassembly, or simply shove something in there to hold the sensor in the 'closed' possition (If you lose a finger or two using this method, don't blame me).
