How to choose the right ink cartridge for HP DeskJet 990c When selecting ink for HP DeskJet 990c, focus on two things: the cartridge code and your printing style. The most common identifiers in this printer family include 51645AE (black) and C6578AE / C6578DE (colour). If you print mostly text, choose a black cartridge or black multipack. If your pages often include charts, logos or school projects, add a colour cartridge or go for a set. Typical user issues with older inkjet models like the 990 c are: - streaks or missing lines – often caused by a cartridge nearing the end of life or long breaks between prints,
- faded colours – usually solved by replacing the colour cartridge and running a standard cleaning cycle,
- cartridge not recognised – in many cases, reinserting the cartridge and cleaning contacts helps.
If you print rarely, we recommend printing a simple test page from time to time—this helps keep the ink system in good condition.
