Abstract
A print assembly for pagewidth inkjet printing that includes an elongate carrier that is mountable on a support structure of a printer in an operative position with respect to a platen of the printer. A number of printhead chips are positioned on the carrier. The printhead chips together define a printhead that is configured to eject at least one billion drops per second into a printing zone defined between the printhead and the platen of the printer. Control circuitry is also positioned on the carrier and is configured to control operation of the printhead chips.
Claims16
A method of pagewidth printing, the method comprising the steps of:
- feeding a print medium through a printing zone;
- and
- ejecting drops of ink at a rate of at least one billion drops per second from a print assembly on to the print medium in the printing zone to generate an image on the print medium.
A print assembly for pagewidth inkjet printing, the print assembly comprising
- an elongate carrier that is mountable on a support structure of a printer in an operative position with respect to a platen of the printer;
- a number of printhead chips that are positioned on the carrier, the printhead chips together defining a printhead that is configured to eject at least one billion drops per second into a printing zone defined between the printhead and the platen of the printer;
- and
- control circuitry that is also positioned on the carrier and that is configured to control operation of the printhead chips.
An inkjet printer that comprises
- a support structure;
- a platen positioned in the support structure;
- a print assembly positioned operatively with respect to the platen, the print assembly comprising
- an elongate carrier;
- a number of printhead chips positioned on the carrier, the printhead chips together defining a printhead that is configured to eject at least one billion drops per second into a printing zone defined between the printhead and the platen;
- and
- control circuitry that is also positioned on the carrier and that is configured to control operation of the printhead chips;
- and
- a feed mechanism positioned on the support structure for feeding a print medium though the printing zone.
