Hi, I'm Robert and I'll be helping you with your printer question.
does the tray seem to click in or does it hit something and not make it all the way in ?
The tray seems to click into the proper position
It may be a bad sensor, I can get you instructions to clear paper jams and maybe figure out how to take it off but if its clicking in properly that sounds like its not the issue.
what is the exact complete word for word message that you are receiving
I want to know how to remove the tray.
It looks like it is not designed to come out. You might have to remove the entire printer housing around it. There are probably some snaps on it that you can get to from the bottom or if you remove the housing.
Why don't you try these instructions first however.
