Xerox printers dominate enterprise offices, but the cartridge naming convention is its own puzzle: 106R02773, 106R03773, 106R04381 — and every series has a different chip, regional SKU, and yield. Order by brand alone and you'll learn the hard way. This guide decodes the 106R numbering, maps cartridges to the right VersaLink, WorkCentre and Phaser machines, and shows where compatible Xerox toner can save 40–60% without hurting print quality.
Why 2026 is a turning point for Xerox compatible toner
In May 2026, Xerox released the first unified-brand hardware (C240, C245, C255a, C300/C303a/C305ae) after its integration with Lexmark. Procurement teams managing mixed fleets will see more Xerox-branded machines installed through 2026 and 2027, which directly expands the 106R installed base. For wholesalers and IT buyers, it's the right moment to stock compatible 106R cartridges. For the wider cost-vs-quality math, see our OEM vs compatible toner comparison.
Decoding the 106R numbering system
Every genuine Xerox toner starts with the prefix 106R, followed by a 5-digit code. The digits cluster by machine family:
- 106R0xxxx — older Phaser / WorkCentre 65xx / 75xx generation
- 106R02xxx — Phaser 6600 and WorkCentre 6605 entry color series
- 106R03xxx — mid-cycle B/W WorkCentre 33xx and VersaLink B400 series
- 106R04xxx — VersaLink C400/C500 and B600/B610 enterprise series
- 106R05xxx+ — current production VersaLink and the new C240/C245 family
Regional variants in the last two digits and on the package label matter: a 106R SKU sold for the U.S. may not be the exact one for the EU even when the toner is mechanically identical. Always match the SKU printed on your empty cartridge, not the description on the seller's listing.
VersaLink, WorkCentre, and Phaser cartridge map
| Family | Typical Use | Cartridge Reference |
|---|---|---|
| VersaLink B400 / B600 / B610 | Enterprise mono, 47–65 ppm | 106R04381 std, 106R04382 high yield |
| VersaLink C400 / C405 | Workgroup color, 35 ppm | 106R03532 K, 106R03533 C/M/Y |
| WorkCentre 6515 | SMB color MFP | 106R03680 K, 106R03676 C/M/Y |
| WorkCentre 3345 / 3325 | Small workgroup mono MFP | 106R03773 (3,000 p), 106R03774 (8,500 p) |
| Phaser 6600 / WorkCentre 6605 | Legacy SMB color | 106R02226 K, 106R02228 C/M/Y |
The cleanest way to find the right cartridge: open the front cover and read the SKU label on the cartridge itself. You can also browse our Xerox cartridge catalog for a printer-to-cartridge map.
Compatible Xerox toner: what changes, what doesn't
For most enterprise SKUs (VersaLink B400, C400, WorkCentre 3345/6515), compatible 106R cartridges from established aftermarket factories now reach ISO yield parity and OEM-equivalent print quality. The real differences:
- Chip — quality compatibles ship with the latest chip firmware (e.g., 106R04381-compatible chips matching the Q3 2026 firmware); older chip revisions can cause false "toner low" readings.
- Print quality — black-on-white is essentially indistinguishable. Color graphics on premium coated paper may show a slight tonal shift on cheap compatibles; mid-tier compatibles match OEM within ΔE 3.
- Firmware updates — Xerox occasionally pushes firmware that blocks older chips. A reliable supplier refreshes chip firmware every 60–90 days.
- Warranty — using compatible cartridges cannot void the printer warranty on its own (U.S. Magnuson-Moss and similar EU rules), but the OEM won't pay for damage caused by a defective compatible.

Common ordering mistakes to avoid
- Buying "for Xerox" without checking the SKU — VersaLink and WorkCentre machines in the same office often use different cartridges
- Confusing standard and high-yield SKUs — they look identical from the outside
- Choosing the wrong regional variant (106R-NA vs 106R-EU) — chip is the same, warranty differs
- Forgetting the drum unit — VersaLink B600/B610 and WorkCentre 3345 use separate toner + drum; replace the drum only on the warning
Frequently Asked Questions
Will a compatible Xerox toner void my printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act and equivalent EU consumer law, using compatible cartridges cannot void the printer warranty on its own. The OEM is only allowed to refuse claims for a defect they can prove was caused by the compatible cartridge.
Which Xerox models have the largest compatible supply chain today?
VersaLink B400 / B600 / B610 and WorkCentre 3345 / 3325 are the most actively supported. The new C240/C245/C255a family released in May 2026 is ramping up — expect broad compatible availability by Q1 2027.
How much can I save vs OEM on Xerox compatible toner?
40–60% off OEM list for the standard 106R SKUs, and 30–50% off on the high-yield family. Fleet buyers who order monthly see the steepest discounts.
How do I know if my Xerox is mono or color?
The model number gives it away: VersaLink B-series and Phaser 30xx/33xx/36xx are mono. VersaLink C-series, WorkCentre 65xx/75xx, and Phaser 60xx/65xx are color.
