Printhead
ComponentsDefinition
The component that deposits ink onto the media. DesignJet printers use thermal inkjet printheads that fire tiny droplets of ink through microscopic nozzles.
In-Depth Explanation
Printheads are consumable components that degrade over time. They contain hundreds of nozzles that must fire precisely to produce accurate prints. Common issues include clogged nozzles (causing banding), electrical failures (error codes like 12:10), and alignment problems. Most modern DesignJet printers use replaceable printheads that can be swapped without tools. Regular printhead cleaning and alignment calibrations help extend their lifespan.
