This machine has an issue with size mismatch, For example the machine is set for plain letter in portrait position. Tray 4 is default, when trying to print or copy, the machine will not pull the paper, instead it says there is a size mismatch in the tray, turn it to letter "r" and same thing. On the control panel, the choice for letter in portrait is faded out so it can't be selected. While messing with it, tray 3 started doing it, then I rebooted it and 3 worked and 4 was still jacked.

Can't find anything physically broke, I ask the key opp to have his firmware reloaded while I research. Any ideas?
