Product Description

The HP C4908A remanufactured magenta ink cartridge from Castle Ink is a direct replacement for the OEM HP C4908A, built for HP LaserJet, OfficeJet, DeskJet or DesignJet office printers. It’s an economical way to keep your printer in service without paying full OEM prices, while still meeting the print-quality standards your team expects.

Magenta is where most compatible cartridges show their weakest spot. The C4908A is formulated to match OEM magenta density, so brand reds, pinks and skin tones print true — not salmon, rose, or shifted toward orange. Every C4908A is assembled with a sealed ink reservoir, OEM-spec print-head interface, and color-balanced ink, then individually tested before shipping. Castle Ink backs every C4908A with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions

Will the C4908A void my HP printer warranty? No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.

How does print quality compare to the genuine HP C4908A? The C4908A is engineered to match the OEM cartridge’s ink chemistry, density and head-firing characteristics so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.

How fast will my order ship? Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping. Expedited options are available at checkout.
