Lexmark 79L2HC0 toner cartridge, cyan, 46,900 pages, CX833se/CX950se/CX951se

According to Lexmark, one 79L2HC0 cartridge lasts for 46,900 pages. That is a manufacturer figure, and the real result depends on how much cyan your pages need. Blue logos, charts and photos use more of it than ordinary black text, which takes almost no colour toner at all.

A colour printer builds the image from four toners: cyan, magenta, yellow and black. The 79L2HC0 is the cyan, a blue-green shade. Because each colour sits in its own cartridge, you replace only the one that has run out while the others keep working. The same series also comes in black (79L2HK0), magenta (79L2HM0) and yellow (79L2HY0).

The supplier data lists the Lexmark CX833se, CX950se and CX951se as compatible printers. No other models are listed. The model code is shown on the front panel or label of the printer; if it is one of these three, the 79L2HC0 is its cyan cartridge. The same compatibility list applies to all four colours of the series.

The cartridge is made by Lexmark, so it is the printer maker's own consumable rather than a compatible copy. It weighs 0.80 kg. Keep a spare in its original packaging in a cool, dry place and open it only when the printer reports that cyan toner is running low.

Offices and teams with a Lexmark CX833se, CX950se or CX951se that print plenty of colour presentations, reports or marketing material; admin and IT teams that keep consumables in stock and prefer the original; and companies that want a high-yield cartridge to reduce the number of swaps.
