Lexmark 20K Return Program toner cartridge CS720/CS725, black, 20,000 pages

According to Lexmark, one cartridge lasts for 20,000 pages. Page yield is a manufacturer figure, and the real result depends on what you print: pages with dense graphics, logos and filled areas use more toner, so you get fewer of them. In an office that prints invoices, contracts and reports every day, a high yield means cartridge swaps do not become a weekly chore and a spare does not have to sit on the shelf all the time.

The cartridge is intended for the Lexmark CS725de, CS720de, CS720dte and CS725dte – that is the complete list given in the supplier data. You will find the model name on the front panel or on the label of your printer. Compatibility with other Lexmark models is not confirmed, so it is worth checking your printer's model code against this list before you order.

Return Program is part of the official Lexmark product name and sets this cartridge apart from other variants. The exact programme terms, such as how used cartridges are returned, are not described in the supplier data. If that matters to your company, check the terms with Lexmark. For comparing cartridges, the data lists black toner, laser technology and a yield of 20,000 pages.

Lexmark is listed both as the manufacturer and as the compatible brand, so this is the printer maker's own consumable rather than a compatible copy. In a laser printer, fine toner powder is transferred to the paper and fused with heat, which means pages come out dry and can be handled straight away. Black toner suits crisp text, tables and barcodes.

The cartridge weighs 0.475 kg and the pack contains one cartridge. It makes sense to keep a spare in its original packaging in a cool, dry place and open it only when the printer reports that toner is running low. That way the toner stays ready to use and a swap does not hold up the working day for long. With a yield this high, one spare per printer is usually enough.

Offices and teams running Lexmark CS720de, CS720dte, CS725de or CS725dte printers that print a lot of black text; IT and office managers who prefer the printer maker's original consumables; and companies that want a high-yield cartridge to cut down on swaps and reorders.
