How to choose the right ink for HP K850dn (and avoid common problems) When selecting ink cartridges for HP OfficeJet Pro K850dn, start with the code printed on your current cartridge or in the printer manual. The most common customer mistakes are mixing cartridge families (HP 10/11 vs HP 13) or overlooking the fact that print quality issues may come from a worn or clogged printhead rather than the cartridge itself. Typical issues reported with the K850dn and how to handle them: - Streaks or missing color – often indicates a clogged or failing printhead; consider HP 11 printhead replacement or use the cleaning fluid.
- Faded prints – check if the correct cartridge is installed and not near empty; run a cleaning cycle and ensure vents are unobstructed.
- Color inconsistency – replace the affected color cartridge (e.g., C4836AE cyan) and verify printhead condition.
- Printer used infrequently – ink can dry in nozzles; preventive cleaning and proper shutdown help a lot.
