Setup, Compatibility & Care
To install the DR-248CL, power down your printer and open the front access panel. Remove the old drum unit assembly according to your printer's user manual, and carefully insert the new units. Avoid touching the surface of the drum rollers with your bare hands, as natural oils can leave permanent marks that degrade print quality.
This unit is compatible with models including the HL-3040CN, HL-3070CW, MFC-9010CN, and MFC-9320CW. Keep the units in a cool, dry place away from direct sunlight when not in use. If storing, ensure they remain in their original packaging to prevent dust buildup or light exposure.
