The HP 122 Black Original Ink Cartridge (CH561HE) is a genuine HP pigment-ink black cartridge for HP DeskJet printers that use the 122 cartridge family, including the DeskJet 1000 (J110 series) named by the supplier. Pigment black ink gives crisp, smudge-resistant text for homework, letters and everyday documents. Icecat's HP datasheet gives 2 ml of ink and an ISO yield of about 120 pages, while the supplier's description states 190 pages; the true figure depends on the page content. It is used together with the separate HP 122 tri-colour cartridge. HP specifies operation between 15 and 32 degrees Celsius and 20 to 80 percent relative humidity, with storage between -40 and 60 degrees Celsius. The cartridge weighs about 27 g, and HP lists 70 percent overall recycled content in its build.
