Pagewidth printhead with more than 100000 nozzles
Abstract:
A pagewidth inkjet printhead that has an array of droplet ejectors for ejecting drops of printing fluid onto print media fed passed the printhead in a media feed direction. Each drop ejector having a nozzle and an actuator for ejecting a drop of printing fluid through the nozzle. The array has more than 100000 of the droplet ejectors and extends in a direction transverse to the media feed direct between 200 mm and 330 mm. A pagewidth printhead with a large number of nozzles extending the width of the media provides a high nozzle pitch and a very high ‘true’ print resolution—i.e. the high number of dots per inch is achieved by a high number of nozzles per inch.
