How often should printheads be replaced?

Generally printheads should serve you 1.5 - 2 years before giving any problems like print quality issues. You shouldn't need to replace them until you see a message on the printer instructing you to do so.

How do I know if I need to replace my printhead?

Faint, streaky or spotty prints are all common signs of a clog but a simple cleaning can usually get your HP ink cartridges working again. Printheads clog due to infrequent cartridge use. If you regularly go a few weeks without printing, your cartridges will eventually dry out and need to be replaced.
