Frequently Asked Questions
Which channel does the CB403A refill?
Magenta — the code ending in 3 in the 642A family. This CB403A is the magenta supply for the Color LaserJet CP4005 printers, and verifying that code against your old cartridge guarantees the right color the first time.
What symptoms point to a fading magenta cartridge?
Reds weaken toward orange, purples wash out, and skin tones pick up an unnatural green-gray cast. Magenta does heavy work in photographs and brand colors, so its decline usually shows up in people pictures first.
What yield is this cartridge rated for?
Approximately 7,500 pages under standard coverage assumptions — the same class as the black, cyan and yellow members of the set, which keeps the four channels aging at a similar pace.
Do I need to reset anything after installing it?
No manual reset is involved. Seat the cartridge firmly, close the cover, and let the CP4005 run its automatic calibration; the supply gauge updates itself once the new cartridge is recognized.
How much is the CB403A on this page?
The price is $128.29 for one compatible HP CB403A magenta cartridge, a practical single-color refill for a printer whose other channels still have useful life.
What backing do I get with it?
Every cartridge is covered by a 1-year warranty and our 1-year free returns commitment. Stock sits in Illinois, Pennsylvania, Georgia and California for quick dispatch, and real people answer questions Monday through Friday, 9 AM to 5 PM CST. Read the full policy on the shipping and returns page.
About This HP CB403A Magenta Toner Cartridge
Magenta carries the emotional weight of a color print — it is what makes reds urgent, sunsets warm and faces alive on the CP4005. When it runs low, output turns flat in a way that is hard to name but easy to see. This CB403A restores that channel at a 7,500-page rating, sized to slot into the existing 642A set without throwing the other colors off schedule. Marketing teams and anyone printing photographs or presentation covers will feel the difference immediately: reds regain their edge, purples deepen, and skin tones stop drifting toward an unflattering green. Keep one sealed as a spare and a fading magenta never has to hold up a deadline again.
