HP Q5952AC YLW CONTR LJ TONER CARTRIDGE

HP 643A Yellow LaserJet Toner Cartridge (Contractual), Q5952AC, supplies yellow toner for compatible LaserJet printing. It is the yellow cartridge in the HP 643A family, intended for adding yellow to colour print output.

The contractual part number identifies this version as Q5952AC. HP lists it separately from the standard Q5952A cartridge, so the suffix is part of the product identity. This is a single colour toner cartridge, rather than a set of the complete 643A colour range.
