250-sheet input tray (tray 1)
The input tray holds up to 250 pages of 80 g/m2 or 20 lb paper or fewer pages of heavier media
(25 mm (0.9 inch) or less stack height). Load media with the top forward and the side to be printed
facing down. To prevent jams and skewing, always adjust the side and rear media guides.
NOTE When you add new media, make sure that you remove all of the media from the input
tray and straighten the stack of new media. This helps to prevent multiple sheets of media
from feeding into the all-in-one, which can cause jams.

Hope this helps if not you may have a registration roller problem.

Your description indicates that the problem is with the printer driver settings.
Go to Start, Control Panel, Printers and check the setings for Economode and ReT. The should both be off or Economode=off and ReT set to Med or Dark.
This should fix the problem. Let me know if this works or not and we can try something else.

You need to check the mode your printer is printing in. It may be in diagnostic mode. Another reason for having an extra page with info. is the page isn't setup to print all info on one page. Run your setup allignments and testing options to get it all on one page. Hope this helps. -Jennifer
