Deskjet 3050 falsely reports "open output tray"

[tbuckley]

My Deskjet 3050 reports "Open Output tray" Press OK.  The tray is open and I press okay, but the error keeps appearing.  Is there a sensor that is detached?  How is the printer made aware of the door status?

Hi tbuckley, 

What happens if you open the cartridge door, and then close it?

[tbuckley]

I opened the cartridge door the ! message indicateds it is open;  when I close the door it reverts back to ! open output tray.

Hi tbuckley, 

There is a sensor switch in the lower right hand corner when you lower the paper tray. Make sure that the sensor arm hasn't broken or came unseated from the tray.

very cool; I'm not at home to check but if the switch is damaged can I conntect the wires to force a "always open" situation.

Hi tbuckley, 

Did you check the switch on your printer?

[tbuckley]

The switch is completely gone likely broke off?  Is a replace available or is the printer trashed?  Or an outside chance can we force an open door signal?

Hi tbuckley, 

Do you have an extended warranty on this printer?

This part is not replaceable. The switch is activated when you press straight back toward the printer as if the door was getting closed. You may be able to activate the switch if you can somehow get what is left of the arm pressed back toward the printer. I have included a link to some of our new printers below.

Hi tbuckley, 

Were you able to get the switch enabled?

[tbuckley]

Could not make it work thanks for your help we gave it a good try (switch total busted).
