Everprint CHIP-XER-WC5225-DR is a drum-cartridge chip for Xerox WC5225 and WC5230 devices. It is listed for reference 101R00435, helping identify the drum cartridge type it is intended to serve.
The listing specifies a black chip with a stated yield of 80,000 pages. This is a replacement component for the drum-cartridge assembly, rather than a complete cartridge. Its exact model reference makes it easier to distinguish from the separate toner-cartridge chip listed for the same device family.
