Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That means there is a settings conflict.
How do you have the 'cassette' or paper tray, settings? in either the printer's driver settings on the computer, or in the application program's print settings ?
Let me know, and I will advise you further as to what to do to cure the problem. Thanks.
