C3350 can print to tray 2 from PC

[drowranger]

Will it print from tray 2 if tray 1 is empty or open ?

Try [ Utility] - [User Settings] - [System Settings] - [Paper Tray]
1. Remove tray2 from Auto selection
2. Turn Off Auto tray switching and see if works...

Check [Utility] - [User Settings] - [Printer Settings] - [Paper Setting] -[Paper Tray] as well

Two more questions. How many people print to this machine? Just to confirm, if you empty tray 1 and make a copy, does it automatically switch to tray two without selecting it?

I would not swap out the machine just yet. Mechanically it seems fine. A firmware upgrade would not hurt.

Try using the HP LaserJet CP2020 pcl driver and see what happens. Just tested at my office and it works correctly. If it works for you then it might point to a driver issue.
