How to use

Power off the printer and consult the printer user manual for the correct access procedure. Remove the used drum unit according to the manufacturer's guidance, taking care to avoid exposure to direct light and to handle by the ends to prevent damage to the photoconductive surface.

Store spare drum units in their original packaging in a cool, dry place away from direct sunlight. Replace the drum at or before the point when print defects such as streaks, ghosting, or reduced contrast appear. Use compatible toner cartridges and follow the printer’s maintenance schedule to extend the life of the drum and ensure consistent print results.
