Chips, Printer Messages & Installation
HP LaserJet printers may show a "non-HP supply" or "used supply" notice. Select OK or Continue and print as usual. If a cartridge isn't recognized, remove it, check that all packing tape and the clip are off, and reseat it firmly. Some HP firmware updates have been known to reject third-party chips, so consider turning off automatic firmware updates.

Compatible vs. Remanufactured vs. Original
Original (OEM) cartridges are new from the printer brand and cost the most. Compatible toner, like this one, is newly manufactured from new components to the original's specifications and tested before shipping. Remanufactured cartridges are refilled originals. Castle Ink sells compatible (newly manufactured) toner and drums, and remanufactured inkjet cartridges.
