The specification describes a printer containing an angled printer cartridge and a method for printing using the cartridge. The printer is an ink jet printer which includes a print media movement device for moving a print media having through the printer along a print media path and a printer cartridge attached to the printer at an angle between 0° and 90° relative to an axis perpendicular to an axis along the direction of the media path through the printer. The printer cartridge has a length sufficient to print substantially the entire width of the printed width across the print media and contains a plurality of printheads along at least a portion of the length thereof, each printhead having one or more nozzle arrays. During a printing operation, only a portion of the printheads along the length of the cartridge are activated thus, reducing power consumption during printing. Angling the printer cartridge also has the advantage of increasing the print quality without increasing the density of nozzles in the nozzle array of the printhead.
An ink jet printer including a print media movement device for moving a print media having a printed width through the printer along a print media path and a printhead cartridge attached to the printer at an angle ranging from about 5° to about 85° relative to an axis perpendicular to an axis along the direction of the media path through the printer, the cartridge having a length sufficient to print substantially the entire width of the printed width across the print media wherein the cartridge contains one or more printheads along at least a portion of the length thereof, each printhead having at least two nozzle arrays and at least one ink distribution channel adjacent each nozzle array.
A method for printing which comprises providing a printer containing a media carriage, a print media disposed in the carriage and an elongate cartridge removably attached to the printer and disposed across the carriage at an acute angle ranging from about 5° to about 85° relative to an axis perpendicular to a direction of movement of the print media through the printer, wherein the cartridge contains a plurality of printheads along at least a portion of the length thereof, each printhead containing at least two nozzle arrays, at least one ink distribution channel adjacent each nozzle array and energizing ink imparting devices on the printhead to effect ejection of ink from the printhead in a pattern sufficient to produce indicia on the print media.
