Choose a reference to carry it into your enquiry. This requests a checked match and quotation; it does not place an order or reserve stock.
Match the reference to your printer.
These checked examples apply to the references shown beside them. They are not a complete compatibility list. A higher-capacity cartridge may fit fewer printers than the standard version. Send your full model so we can confirm the right Compatible or Original option.

Different model suffixes, regional cartridges, chips, firmware or subscription arrangements may require a further check. If your model is not listed, ask us to identify your toner.
Check 331 and 431 capacity compatibility
The 20N20 black, cyan, magenta and yellow references cover the listed CS/CX331 and 431 models. The 20N2H high-yield options verified here are assigned to CS331dw and CX331adwe, so check the individual product match before ordering for a 431.
Original standard cartridges are rated up to 1,500 pages and the verified 331 high-yield cartridges up to 4,500 pages under ISO/IEC 19798. Confirm the UK-region cartridge reference; these Original benchmarks are separate from any compatible product's stated yield.
We check suitable Compatible toner first, with Original options also available. Return Programme labels in the reference table refer to Original Lexmark supplies with single-use and return-to-Lexmark conditions. A Compatible product is quoted separately and is not a Lexmark Return Programme cartridge or represented as approved by Lexmark. Tell us about any managed-print arrangement or cartridge warning; we confirm suitability, price and delivery before you order.
Replacing toner or another supply?
Toner, imaging units, photoconductors, waste containers and maintenance supplies are different items. Send the exact printer warning so we can identify the right part. These guides cover ordinary office toner; MICR and unverified managed-print supplies need a separate check.
