Frequently Asked Questions

Will the 6R303 toner cartridge void my Xerox printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, Xerox cannot void your printer warranty solely because you installed a remanufactured (non-OEM) toner cartridge. The 6R303 is designed to drop in as a direct replacement for the OEM part.

What page yield should I expect from the 6R303?
The 6R303 toner cartridge is rated for approximately 3000 pages at standard 5% page coverage (ISO/IEC test conditions). That covers most small-office workloads between cartridge changes.

Which printers use the 6R303?
The 6R303 fits a range of Xerox models, including the 5008, 5008 RE, 5008 S. The full compatibility list is in the Compatible Printers section above - check your printer model there before ordering.

How much will I save versus a genuine Xerox 6R303?
At $59.95, the Castle Ink 6R303 is about 50% less than the typical OEM retail price of $119.97. For users printing regularly, that saving compounds quickly across replacements.
