Question about HP Officejet Pro K850 InkJet Printer
Have a 1 year old HP Officejet Pro K850 with a "door open" light that seems to be stuck on. Have checked and rechecked all doors and access panels, even uninstalled and reinstalled the duplex unit. Have no idea why the door light is still on.
There is a problem with the proximity sensor for the top door. I have took mine off and soldered the connections over to trick it into thinking the door is closed all the time. I am trying to source a new part
