Hi sunadvocate,
Thank you for using the Support Forum. Please take a look at the solution for selecting paper from wrong tray. Unfortunately it looks like you can not change the default paper source, but to confirm please consider contacting your support centre for further assistance.
Is there a way to make tray 2 the default paper source in a Phaser 3250, so that when a print job that doesn't request a specific paper source (i.e. tray 1, tray 2, MBF, etc) is received by the printer, it automatically goes to tray 2 first and tray 1 second?
