Abstract
A printhead assembly include a carrier, a first plurality of printhead dies each mounted on the carrier and adapted to print a first color, and a second plurality of printhead dies each mounted on the carrier and adapted to print a second color. Each of the first plurality of printhead dies are offset from and partially overlap an adjacent one of the first plurality of printhead dies, and each of the second plurality of printhead dies are offset from and partially overlap an adjacent one of the second plurality of printhead dies.
Claims35
A printhead arrangement, comprising:
- a first printhead assembly including a first carrier, a first plurality of printhead dies each mounted on the first carrier and adapted to print a first color, and a second plurality of printhead dies each mounted on the first carrier and adapted to print a second color;
- and
- a second printhead assembly including a second carrier, a third plurality of printhead dies each mounted on the second carrier and adapted to print a third color, and a fourth plurality of printhead dies each mounted on the second carrier and adapted to print a fourth color,
- wherein the first printhead assembly and the second printhead assembly are in-line and fully overlap.
A method of forming a printhead arrangement, the method comprising:
- forming a first printhead assembly, including providing a first carrier, mounting a first plurality of printhead dies each adapted to print a first color on the first carrier, and mounting a second plurality of printhead dies each adapted to print a second color on the first carrier;
- forming a second printhead assembly, including providing a second carrier, mounting a third plurality of printhead dies each adapted to print a third color on the second carrier, and mounting a fourth plurality of printhead dies each adapted to print a fourth color on the second carrier;
- and
- positioning the first printhead assembly and the second printhead assembly in-line, including fully overlapping the first printhead assembly and the second printhead assembly.
A method of printing, comprising:
- ejecting a first color ink from a first plurality of printhead dies of a first printhead assembly;
- ejecting a second color ink from a second plurality of printhead dies of the first printhead assembly;
- ejecting a third color ink from a third plurality of printhead dies of a second printhead assembly;
- and
- ejecting a fourth color ink from a fourth plurality of printhead dies of the second printhead assembly.
A method of printing, comprising:
- providing a plurality of in-line printhead assemblies each including a first plurality of printheads configured to print a first swath and a second plurality of printheads configured to print a second swath adjacent the first swath;
- supplying different ones of black, cyan, magenta, and yellow inks to the first plurality of printheads of different ones of the printhead assemblies in a first order;
- and
- supplying different ones of black, cyan, magenta, and yellow inks to the second plurality of printheads of corresponding different ones of the printhead assemblies in a second order reversed from the first order.
A printhead arrangement, comprising:
- means for printing a first color and a second color with a first printhead assembly;
- means for printing a third color and a fourth color with a second printhead assembly in-line with and fully overlapping the first printhead assembly;
- and
- means for printing the first color and the third color within a first area, and printing the second color and the fourth color within a second area adjacent the first area.
