Ink cartridge door open when it’s closed. Tried everything, from shutting down printer, unplugging it restarting still I get a message” Ink cartridge door open”

 

 

I think I solved the problem. When you take the ink cartridge cover of the printer there is a circuit board on the left hand side looking from the front. On that circuit board there is a black chip that looks like a U that’s the micro switch (chip) that aligns with the cover switch. Mine was broken off. Now need to solder it back on.
