So my printer showed "printer head missing or ....."
After I tried all the cleaning which doesn't solve the issue. I borrowed another printhead that comes from the same model to test if the printhead is broken.
Now the screen showed:"cartridge only can use the initial installed." and the printhead is staying inside and won't move out after i open the door. so I cant change the printhead back. also, the touch screen is not working but stuck on that error.

Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
