I have a HP 4600 dtn networked configured printer on tcp/ip that over twenty users access. Suddenly, two weeks ago, the printer stop allowing printing automatically from either tray 2 or tray 3. When a print job goes to tray 2 or tray 3, the printer panel prompts the user to manually feed paper into tray 1. If the user selects from the printer panel to print from tray 2 or tray 3 they must scroll through the menu and press the appropiate button. How can I get the printer to reset to automatically print from tray 2 or tray 3 without user invtervention at the printer panel. Thank you very much.
