Supply messages: if the printer shows a "non-genuine" or "used supply" notice, press OK or Continue to keep printing. If the cartridge isn't recognized, check that all packing material is off and reseat it firmly.

Streaks or faint print: rock the cartridge again to redistribute the toner and print a cleaning page from the printer menu.

Compatible vs. Remanufactured vs. Original

Original (OEM) supplies are new from the printer brand and cost the most. Compatible supplies, like this one, are newly manufactured by a third party to the original's size and page-yield specifications, so they drop into the same slot at a much lower price. Remanufactured supplies are emptied originals that have been cleaned and refilled.
