Frequently Asked Questions
What part number identifies the magenta for this printer?
C9733A, the magenta cartridge in the 645A range. The cartridge already in your machine is stamped with the same code, and matching stamp to listing is the complete identification check.
The red cars in our brochures are printing orange. What is going on?
Magenta is going on — out. A brochure red is mixed from magenta and yellow, and as magenta fades the red slides toward orange while the rest of the page can still look respectable. Showroom print is unforgiving about this, and this cartridge is the fix.
What does the extra tray on the dtn mean for brochure printing?
It lets the dealership keep brochure stock loaded permanently while plain paper sits in the other tray. Brochure stock carries the heaviest color on the site, so that tray pairing also tells you which work is spending this cartridge. It also means a brochure reprint never waits on someone swapping paper in and out between jobs.
We reprint brochures in small batches all month. Does that pattern wear the cartridge unevenly?
No — toner consumption follows total coverage, not batching. Ten batches of fifty brochures spend the same magenta as one run of five hundred, assuming the artwork is the same.
How does brochure work stack up against the 12,000-page rating?
Brochures are rich printing: full-bleed photos, saturated color, minimal white. Count on the rating shrinking substantially under that workload and keep the reorder point early — a brochure run should never discover an empty cartridge.
What guarantee accompanies this cartridge?
A 1-year warranty, with 1-year free returns alongside it. Dispatch runs from our warehouses in Illinois, Pennsylvania, Georgia and California, the support desk answers Monday through Friday, 9 AM to 5 PM CST, and the shipping and returns page gives the full picture.

For $166.60 and a 12,000-page rating, this C9733A magenta cartridge serves the HP Color LaserJet 5550dtn in the most color-critical corner of a dealership: the brochure rack, where a red car has to print red.
