Maintain image formation in compatible Xerox monochrome laser printers with a replacement imaging drum unit rated for 10,000 pages. The drum is the photosensitive component that receives the electrostatic image before toner is transferred to paper. Replacing it at the printer's drum-life interval helps retain consistent print output and keeps the imaging system operating as intended. PCI 101R00474-PCI is a compatible replacement for the Xerox 101R00474 and 101R474 imaging drum references. It supports Xerox Phaser 3052 and Phaser 3260 printers, plus Xerox WorkCentre 3215 and WorkCentre 3225 multifunction printers. Verify the printer family and the drum reference required by the installed device before replacement, since the drum unit must match the printer's imaging assembly. This is an imaging drum unit, not a toner cartridge. Its 10,000-page yield identifies the expected drum-life capacity, making it suitable for maintaining supported desktop laser printers and compact multifunction systems. Supplied as one compatible monochrome laser-printing consumable, it provides a PCI-branded alternative for systems that specify the listed Xerox drum reference.
