The HP 131A (CF210A) is the original HP black LaserJet toner cartridge for the HP LaserJet Pro 200 color M251 printer series and the LaserJet Pro 200 color MFP M276 series, compact colour laser machines popular in small offices. It is a standard-yield black cartridge rated for about 1,520 pages, and is used alongside the matching 131A cyan, magenta and yellow cartridges. HP designs it for professional-looking documents and marketing material with sharp black text and consistent results, and the cartridge communicates with the printer so remaining toner can be monitored. Using Original HP toner helps avoid the reprints, leaks and cartridge failures that can come with low-cost clones. The box contains the toner cartridge and a recycling guide; empties can be returned through HP Planet Partners where the programme runs. The boxed cartridge measures about 365 x 100 x 110 mm and weighs around 600 g. HP recommends operating between 15 and 25 degrees C and storing between -20 and 40 degrees C. The cartridge contains 19% recycled content.
