LD Products no longer carries the Xerox 8R7904 and 8R7903 laser toner cartridges for the Xerox DocuPrint C15 . We strive to carry the largest selection of ink and toner cartridges. Unfortunately, there are only a few Xerox DocuPrint C15 printers out there, and even fewer compatible or remanufactured supplies, therefore, we no longer stock these cartridges. Need a new printer?
