How to use
Turn off the printer or switch it to standby according to the manufacturer’s instructions before replacing the cartridge. Open the printer’s toner access panel, remove the empty cartridge following the printer’s removal procedure, and unpack the remanufactured cartridge. Gently shake the cartridge side to side if recommended, remove any protective seals, and insert it into the correct slot until it clicks into place. Close the access panel and restore power; allow the printer to initialize and recognize the new cartridge. Run a test print or calibration page if available to verify correct installation and print quality.
Usage recommendations
Store the cartridge in a cool, dry place away from direct sunlight. For consistent print density, use on suitable paper types recommended for laser printing and perform regular printer maintenance such as cleaning the drum and feed rollers. Replace the cartridge when print quality degrades or toner low warnings appear. Follow local guidelines for disposal or recycling of remanufactured toner cartridges.
