HP C8551A 822A cyan toner cartridge supplies cyan toner for the HP Color LaserJet 9500 printer series. It is the HP Color LaserJet Smart Print Cartridge identified by the exact part number C8551A, for replacing the cyan cartridge in a supported printer.
Its stated average yield is approximately 25,000 pages at 5% coverage. Actual output depends on page coverage, so this figure is a reference for the specified test coverage rather than a fixed page count for every job.
HP’s product information also describes Smart Printing features that report supply status and provide alerts when toner is low or depleted. The cartridge is intended for colour printing workflows, including higher-volume document production on the compatible printer family.
