Compatible 645A Three-Colour Pack

This three-pack contains cyan, magenta and yellow cartridges that replace HP 645A originals C9731A, C9732A and C9733A. Each unit is rated for approximately 12000 pages at five percent coverage. The set is built for HP Color LaserJet 5500 series printers.

Suits 5500-series owners needing colour

Offices running a Color LaserJet 5500, 5500DN, 5500DTN or 5550N can drop these in for standard-yield colour output. Shops that require black toner, high-capacity cartridges or support for other printer families will need a different product.

Drop-in installation with standard alignment

Cartridges seat in the same slots as the OEM equivalents and the printer recognises them without extra steps. The most common issue is forgetting to remove the sealing tape before closing the cover, which blocks toner flow and produces blank pages.

Questions about this item

Which printer models will the 645A 3-pack work with out of the box?

The cartridges are listed as compatible replacements for the HP Color LaserJet 5500, 5500DN, 5500DTN and 5550N printers.

If I keep my existing HP 645A black cartridge (C9730A), will these three colour cartridges operate alongside it?

Yes, the pack contains cyan C9731A, yellow C9732A and magenta C9733A cartridges designed to work with the black C9730A already in the printer.

How can I verify the cartridges are delivering the rated 12000-page yield at 5% coverage?

Print a supplies status page from the printer menu; it shows pages printed per cartridge so you can track actual yield against the 12000-page rating.
