Frequently Asked Questions

The cartridge inside our printer is stamped C9731A. Is that the cartridge this listing sells?

Yes. C9731A is the cyan cartridge of the HP 645A family, and that stamped code is the surest way to order: read it off the cartridge you pull out, match it against the C9731A on this page, and the color and the fit are both settled before you spend anything.

How many pages does one C9731A deliver?

It is rated at 12,000 pages at standard coverage. On the big A3 sheets these printers are usually bought for, a page carries far more image than a letter page, so a poster-heavy month works through the rating faster in calendar time even though the per-cartridge measure still holds.

What does the cyan cartridge actually do in our prints?

Cyan builds the blues and greens: skies, water, corporate blue logos, and the cool half of most photographs. When it runs low the balance tips warm — blues slide toward purple and greens lose their depth — usually on the largest, most visible sheets first.

Our studio prints proofs and posters in bursts, then nothing for a week. How should we stock this?

Keep one sealed spare on the shelf. Burst work means a cartridge can go from fine to faded inside a single job, and a spare turns that into a two-minute swap instead of a missed deadline while a delivery is in transit.

Can I stretch a fading cartridge to finish a run?

A gentle side-to-side rock redistributes the toner inside and often buys a few dozen acceptable pages. Treat it as a bridge to the spare, not a fix — color balance does not fully recover, and proofs judged for color should wait for the fresh cartridge.

What support comes with this cartridge?

Every cartridge is covered by a 1-year warranty with 1-year free returns. Orders ship from our warehouses in Illinois, Pennsylvania, Georgia and California, our team answers Monday through Friday, 9 AM to 5 PM CST, and the shipping and returns page lays out the terms in full.

About This C9731A Cyan Cartridge

This C9731A cyan cartridge, priced at $166.60, keeps an HP Color LaserJet 5500 doing the work it was bought for: tabloid-size color that holds its blues. It suits studios, marketing desks and print rooms that judge output by eye — the buyers who notice a sky drifting purple before anyone else does — and who would rather reorder by the code on the cartridge than by guesswork.
