Check the type of media loaded in the device

Make sure the tray supports the type of media you have loaded. For more
information, see

Understand specifications for supported media


Make sure you have selected the tray in the print driver that contains the media
that you want to use.

Check the device location and length of USB cable
High electromagnetic fields (such as those generated by USB cables) can sometimes
cause slight distortions to printouts. Move the device away from the source of the
electromagnetic fields. Also, it is recommended that you use a USB cable that is less
than 3 meters (9.8 feet) long to minimize the effects of these electromagnetic fields.
