How to use

Turn off the printer and open the front access panel or toner compartment following the printer manufacturer's instructions. Remove the empty cartridge by grasping its handle and pulling straight out. Unpack the replacement Prism Black 90X cartridge, remove protective seals if present, and gently rock the cartridge side to side to distribute toner evenly before installation. Insert the cartridge into the correct slot until it clicks into place, close the access panel, and power the printer on. Perform a test print or printer alignment if the device prompts.

Usage recommendations

Store the cartridge in its original packaging until use, in a cool, dry place away from direct sunlight. Handle the cartridge by its plastic housing to avoid contact with toner. For consistent print quality, allow the cartridge to acclimate to room temperature before installing if it has been exposed to cold or hot conditions. Replace the cartridge when print density decreases or when the printer indicates low toner.
