Restore factory image transfer and maintain print stability with the Xerox Color 500 Series CRU K drum (013R00663). As a customer-replaceable unit (CRU), this black drum is engineered to meet Xerox tolerances for surface finish and transfer characteristics, reducing banding, streaking, and density variance that compromise production jobs. For IT teams managing mixed fleets or high-value color workflows, the CRU K drum simplifies service workflows: technicians and trained operators can swap the unit to return printers to spec without extended downtime. Choosing the OEM CRU minimizes troubleshooting time and supports predictable output — a cost-effective choice where color accuracy and uptime are priorities.
