Chips, Printer Messages & Installation

Installing: open the machine's cover, lift out the empty cartridge, then rock the new cartridge gently side to side five or six times. Pull the seal straight out, slide the cartridge in until it seats and close the cover.

Supply messages: if the machine still shows a toner warning, open and close the cover once or power it off and on.

Streaks or faint print: rock the cartridge again and run a few copies. The drum is built into this cartridge, so a new cartridge also renews the drum.

Compatible vs. Remanufactured vs. Original

Original (OEM) toner is new from the printer brand and costs the most. Compatible toner, like this cartridge, is newly manufactured by a third party to the original's size and page-yield specifications, so it drops into the same slot at a much lower price. Remanufactured toner is an emptied original cartridge that has been rebuilt and refilled. Castle Ink sells compatible (newly manufactured) toner and remanufactured inkjet cartridges.
