Brother MFC-L2980DW Monochrome Laser All-in-One Printer

Make sure to keep your printer up to date by downloading drivers and patches from the manufacturer's site. Most manufacturers provide driver updates for their units which include patches that add fonts or fix incompatibilities.

Most printers have a built-in diagnostics program which can be very useful for troubleshooting problems and test-printing without a computer. They are usually initiated by pressing a button or two while turning on the printer.

Is your printer feeding in the whole paper stack rather than just one piece at a time? Fan the paper before putting it in the tray to help separate the sheets. Also, store your paper in a cool, dry place as humidity can contribute to this problem.
