Abstract
A method and printer for priming an inkjet printhead without removing the printhead from a carriage of the printer, by the controlled delivery of a predetermined volume of gas to an air chamber within the printhead so that the air chamber expands within the printhead body causing an increase in the ink pressure within the printhead and thus a controlled flow of ink into the nozzles of the printhead. An ink puddle may be formed on the nozzle plate of the printhead during priming and subsequently drawn back into the printhead.
