Tip & How-To about Lexmark MFP-X3470 All-In-One InkJet Printer
This is a common fail in this model. there is a white plastic arm which works as an extender for the switch that senses if the cover is open or closed. This part is easily detached from its place (in my case not broken but it could happen I suppose) resulting in printer showing the message "Cover open" / "Cub abierta". the switch is situated under the scanner in the middle . when you lift the scanner part to see the ink cartridge, you see a plastic part underneath between the hinges that looks like a 2/3 of a circle that is the part that pushes the switch.
You should open the printers gut and place the loose part back in place. Be ware that flat cables' contact ends could easily brake! use precaution!
(if you shake your printer you may hear the sound of the lose part).
Happy solving problems!
