The HP CB387A remanufactured magenta drum unit from Castle Ink is a direct replacement for the OEM HP CB387A, 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 CB387A is formulated to match OEM magenta density, so brand reds, pinks and skin tones print true — not salmon, rose, or shifted toward orange. Every CB387A 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 CB387A with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.Compatible HP Printers HP Color LaserJet CM6030 HP Color LaserJet CM6030f HP Color LaserJet CM6040f HP Color LaserJet CP6015de HP Color LaserJet CP6015dn HP Color LaserJet CP6015n HP Color LaserJet CP6015x HP Color LaserJet CP6015xh Product Specifications SKU: CB387A OEM Reference: HP CB387A Color: Magenta Cartridge Type: Remanufactured (non-OEM) Format: Drum Unit Brand Compatibility: HP Warranty: Castle Ink 100% satisfaction guarantee Shipping: Free U.S. shipping; same-day dispatch on orders before 2pm ET Frequently Asked QuestionsWill the CB387A void my HP printer warranty?
