Frequently Asked Questions
How do I confirm C9733A is the magenta our machine takes?
Pull the magenta cartridge you are replacing and read its stamp: C9733A is the magenta of the HP 645A family, and a code-for-code match with the cartridge coming out confirms both the color and the fit in one step.
Why do our reds look wrong before anything else fades?
Reds are built largely from magenta, so they are the first casualty as this cartridge empties: brand reds slide toward orange or brown, and purples thin out. On machines that print customer-facing color, the red in a logo is usually the earliest warning you get.
Does magenta matter for photographs, or only for graphics?
It matters a great deal for photographs. Skin tones live in the magenta range, so a tiring cartridge gives faces a greenish, seasick cast long before the supply warning appears. Photo work is also simply thirsty — portraits draw more magenta per page than text ever will.
What page yield is this cartridge rated for?
12,000 pages at standard coverage. Treat that as a budgeting measure rather than a promise: a month of A3 photo proofs and a month of memos with a small logo use the same cartridge at very different speeds.
Our prints have gone greenish overall. Is this cartridge the cause?
Quite possibly. When magenta fades, the remaining colors dominate and the page tips green. Print a test page with a red block: if the red is weak or orange, swap this cartridge before you start adjusting files or settings.
What backing do we get with the purchase?
A 1-year warranty with 1-year free returns stands behind every cartridge. We ship from warehouses in Illinois, Pennsylvania, Georgia and California, answer questions Monday through Friday, 9 AM to 5 PM CST, and publish the full terms on our shipping and returns page.
About This C9733A Magenta Cartridge
At $166.60, this C9733A magenta cartridge serves the HP Color LaserJet 5500 in the work where color is judged hardest: proofs, presentations and photographs. Magenta is the cartridge that decides whether a red is your red and whether a face looks healthy, and this one is rated for 12,000 pages of it — ordered by the code on the cartridge it replaces, so the match is never in doubt.
