Xerox B310/B305/B315 Extra High Capacity BLACK Toner Cartridge (20000 Pages) - Use & Return

The Xerox 006R04378 is a genuine extra-high-capacity black toner cartridge rated for up to 20,000 pages and listed as compatible with the Xerox B310 printer, making it suitable for users who print frequently and want fewer cartridge changes.

Recommended For

• Small offices and home offices with a Xerox B310, B305, or B315 that print black-and-white paperwork steadily and want a higher-yield replacement cartridge.
• Workgroups sharing one of these printers for frequent monochrome document jobs, where the 20,000-page declared yield can mean fewer toner changes than the 3,000- or 8,000-page options.
• B310, B305, and B315 owners who prefer a Xerox-branded cartridge specified for their printer rather than sourcing a generic replacement.
• Office buyers planning toner replenishment around higher-volume black-and-white printing; the listed 20,000-page yield is based on standard test pages and varies with coverage and print mode.
