Where is the cover/lid sensor or switch in a Canon TR8550/TR series?
I'm getting an open cover error message on my TR8550. After no love, I finally disassembled to search for either a switch or sensor. The only one that I can find is the switch for the front panel. I've attached pics of that - I'm pretty sure it's not tied to the opening/closing the lid. Because it generates an error message, it would have to be electrically tied to the MOBO to pass that info to the front panel.
There is a twisted pair cable with plug from the cover/lid but without opening the lid, I can't trace it to see if it is attached to a switch or sensor. That connector is on the top left of the MOBO, along with some ribbon cable connectors.
In any case, I've inspected all around the cover and anywhere the cover makes contact with the printer lower half and can't find any sign of a switch or sensor.
Where it says "front panel", that is only the switch connector not the ribbon cable connector, which I've already removed. This registers if/when the front panel is raised or down.
Front panel switch
From what I can tell, this only serves to register if/when the front panel is raised or down and isn't tied to whether the cover/lid is open or closed.
