Lexmark 79L2HY0 toner cartridge, yellow, 46,900 pages, CX833se/CX950se/CX951se

According to Lexmark, one 79L2HY0 cartridge lasts for 46,900 pages. That is a manufacturer figure, and the real result depends on how much yellow your pages need. Yellow is part of greens, oranges and reds, so it is used most when printing photos, maps and colour charts, while ordinary black text takes almost none of it.

A colour printer builds the image from four toners: cyan, magenta, yellow and black. Each sits in its own cartridge, so when yellow runs out you replace only that one and the other cartridges keep working. The same series also comes in cyan (79L2HC0), magenta (79L2HM0) and black (79L2HK0).

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 79L2HY0 is its yellow 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 yellow toner is running low.

Offices and teams with a Lexmark CX833se, CX950se or CX951se that print plenty of colour presentations, photos, maps 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.
