LaserJet CP4005dn
From the generation of LaserJets that offices bought by the dozen and ran for a decade, the LaserJet CP4005dn is a mid-2000s color single-function printer still earning its desk space. Its supplies are the HP 642A family — CB400A black, CB401A cyan, CB402A yellow and the CB403A magenta listed on this page. Each of the four is tracked and replaced separately.
Offices keep a CP4005dn for one unglamorous reason: it handles everyday document printing without complaint, year after year. That reliability sets the pattern for its supplies too — nothing exotic, just the right color cartridge when the printer asks for it. Magenta tends to be the quiet one, sipping toner on charts and letterheads until the day the gauge says otherwise; when it does, this page has its cartridge.

Which cartridge should you buy?
Let the printer make the decision. The CP4005dn watches each cartridge on its own, so shop only when a color flags low — and if the flagged color is magenta, the compatible CB403A stocked here is the one to order. The other three 642A cartridges are not sold on this page, and swapping a cartridge that still has toner in it buys you nothing. If your office prints color every day, a sealed spare magenta on the shelf turns a low-toner warning into a non-event; either way, the cartridge carries a 1-year warranty and 1-year returns.
Chip, toner and everyday use
A chip on each cartridge feeds the printer's level estimates, which is why the CP4005dn can ask for one color at a time instead of stopping the whole machine. Change a cartridge with clean, dry hands, tape off, and push it in until it clicks into its slot; a short calibration follows automatically. Keep unopened spares away from heat and sunlight, and if a color fades early, rocking the cartridge gently side to side redistributes the toner and usually restores even coverage for the rest of its life.
Frequently Asked Questions
How many cartridges does the LaserJet CP4005dn take?
Four — the HP 642A set: CB400A black, CB401A cyan, CB402A yellow and CB403A magenta. The printer monitors each one on its own, and this page stocks the magenta.
Does the LaserJet CP4005dn need all four cartridges installed to print?
Yes, all four slots must be filled before it will print. The good news is that you only ever replace the one that is actually empty; the others stay in the machine until their turn comes.
How do I connect the LaserJet CP4005dn to the network?
Run an Ethernet cable from the printer to your router or office switch and it picks up a network address automatically. Print a configuration page from the control panel to get its IP address, then install the driver on each workstation.
