The Problem is the Input Tray Will Not Fit Properly
If you have problems inserting the input tray securely, try inserting and removing
the tray two or three times. Normally this should resolve the problem.
However, if it doesn't, check that the latches are correctly positioned.
Inside the slot where the tray goes there are three spring-loaded latches. If they
are not in the correct position, the tray won't fit properly.
Make sure that both latches are forward. If necessary, pull them towards you.
When you insert the tray, you should hear a click as the latches are pushed
back; when you remove the tray, the latches click as they move forward.
