SuppliesMax HP 56 (C8812BN) Black Inkjet Cartridge 3-Pack 450 Pages

Three-Pack Black Inkjet for HP Printers

This three-pack of remanufactured black inkjet cartridges replaces the HP C8812BN model and fits a wide range of DeskJet, OfficeJet, PSC and PhotoSmart printers. Each cartridge is rated for approximately 450 pages at five percent coverage. The pack suits home offices and small businesses that print text documents, presentations and photos on a regular basis. Buyers who need colour output or higher-yield tanks should look elsewhere.

Practical Limits of Inkjet Cartridges

Page yield is measured at five percent coverage, so dense graphics or full-page photos will reduce the actual number of prints. Ink can dry out if the printer sits unused for long periods, which may clog nozzles and require cleaning cycles. The cartridges are engineered for 110 V U.S.-based printers; using them in regions with different voltage standards is not supported. No other interface or technology constraints apply.

Simple Installation With Common Pitfalls

Installation follows the printer’s standard cartridge-replacement routine: open the access door, remove the old unit and insert the new one until it clicks. The most frequent issue is the printer not recognising the remanufactured chip, which is usually resolved by reseating the cartridge or restarting the device. Print-head alignment may be needed after fitting. The manufacturer provides a 30-day warranty against defects.
