Almost every consumable in this section carries a 113R prefix, a numbering scheme that stayed in use after the Tektronix printer line was absorbed into the Xerox range. Black toner such as 113R00668 and 113R00730 handles day-to-day printing, while a drum unit like 113R00670 is a longer-life part replaced only when print defects repeat at a fixed interval down the page. If your printer badge reads Xerox but the cartridge reads 113R, this is still the right place to look.
Standard and High-Yield Black Toner
Several models accept both a standard black cartridge and a high-yield version such as the 113R00657, which prints more pages before it needs changing. High-yield parts suit machines that run long print jobs, while a standard cartridge is fine for lighter desktop use. Because both fit the same printer, the deciding factor is your monthly page count rather than the hardware.
