Hi,
I had the same issue, try this, it worked for me, and prints two pages straight.
I'm using a Mac,
''' COMPUTER SETTINGS'''
Set the document you want to print
In the printer settings, change it to 'US Letter'
'''PRINTER SETTINGS'''
Go to 'paper settings' click OK on 'Cassette' and then press the + button and select 'Ltr' for the paper size. It then displays the words 'plain paper' press OK, and you should be good to print.
Hope it works for you.
