Frequently Asked Questions
What arrives in this three-pack for the 5550dn?
Three C9730A black cartridges — the black unit of the HP 645A family — together at $462.81. They are the standard cartridge for the 5550dn, bought as forward stock for a reports-driven printer.
Why buy three blacks in one order for a reporting office?
Reporting runs in cycles: month-end, quarter-end, board packs. Each cycle is a surge of two-sided text that consumes black in concentrated bursts, and buying against the cycle — once, in quantity — beats scrambling inside it.
What yield does each cartridge carry?
A rating of 13,000 pages at standard coverage, the same as the individually sold cartridge. On duplex reports that figure is consumed in printed sides, so busy cycles move through a unit at a predictable clip.
How do two-sided reports affect the pace through the three?
Both faces of every sheet are printed, and on reports both faces are text. Expect the black to be drawn down roughly twice as fast per box of paper as single-sided work — another reason the third cartridge earns its shelf space.
How should the three be stored between cycles?
Sealed, flat, in a dry cupboard away from heat and sunlight, used in arrival order. Properly stored, a cartridge waits through quiet months and prints normally when the next reporting surge arrives.
What happens if a cartridge from this pack is defective?
Reach our support team Monday–Friday, 9 AM–5 PM CST and describe the output. All three units carry a 1-year warranty and 1-year free returns, with the process set out on the shipping & returns page.

The Color LaserJet 5550dn does its heaviest work in bursts, and bursts are what this pack is for: three C9730A cartridges, each rated at 13,000 pages, bought ahead so a reporting deadline never waits on toner.
