Compare the cartridge references.

The figures below are manufacturer benchmarks for original replacement cartridges, based on ISO/IEC 19798. Actual yield varies with print content and use. Compatible yields may differ; we confirm the exact product specification in your quote.

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.

Choose 78C toner for the listed CS and CX models

The selected 78C20 references cover black, cyan, magenta and yellow standard toner for the listed CS421, CS521, CS622, CX421, CX522, CX622 and CX625 models. Similar C/MC printer names and shared imaging supplies do not establish a toner match.

Original benchmarks are up to 2,000 black or 1,400 colour pages under ISO/IEC 19798. Check the UK/EEA+ reference, colour and exact printer model; larger capacities and compatible-product yields need their own product specification.

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.

What to include for a clear quote.

• Full printer model and cartridge reference, if known.
• Colour and quantity, including individual replacements or a complete set.
• Delivery postcode, deadline and any recognition or firmware message.

We check suitable compatible options first and confirm the product, current price and delivery before you agree an order. Original toner is available if your organisation specifies it.
