ABSTRACT:
An inkjet printhead that has a chamber for holding a quantity of ink, a nozzle in fluid communication with the chamber, a pair of electrodes and, a heater for generating a vapor bubble in the ink to eject a drop through the nozzle. The heater has contacts for electrical connection with the pair of contacts, a heater element suspended in the chamber between the contacts and the nozzle, and sloped side portions extending between the heater element and the contacts. The heater element has higher electrical resistance than the contacts and the sloped side portions.
