The Xerox Phaser 5500 drum cartridge yields up to 60, 000 high-quality pages. Because the drum cartridge is a separate unit from the toner cartridge, both cartridges may be used up completely, enabling overall supplies savings & less waste of unused portions. &, when you are finished with the drum cartridge, Xerox will recycle it for free through our Green World Alliance supplies recycling program. Xerox cartridges are easy to replace & are designed to interact perfectly with other Xerox supplies, ensuring superior print quality & reliability-leaving more time for carefree, unattended printing.
