Hi, When I usually print, I do so via the cassette tray. Yet when some people send me some documents and I try to print, no matter how I set up the printer options, the printer tries to print from the rear tray, which has no paper. I have set the printer preference to print from the cassette, but I just can't seem to overcome this. If I just want to print my own documents it prints as I have selected, i.e. via cassette. I know I could just fill the rear tray, but its not how I want to use my printer.
