When I use eprint to my M602n printers allways uses tray 1. How do I get it to use tray 2?

Hello,

It does not happen with other printers (LaserJet Pro 400 M451dn), but on my HP Laserjet M602n printers, it always holds printouts with message "Load tray 1, plain paper"  "To use another tray press OK".

When I press OK once, it asks another prompt "Use instead Tray 2" "OK".

I have to press OK twice on physical printer before "each page" of that print job.

This printer does not act like this when we send printouts to it from local network (via Computers).  Please help.
