Definitions

  • the small drops of ink are ejected from the nozzles through orifices or nozzles by rapidly heating a small volume of ink located in vaporization chambers with small electric heaters, such as small thin film resistors.
  • small electric heaters such as small thin film resistors.
  • the small thin film resistors are usually located adjacent the vaporization chambers. Heating the ink causes the ink to vaporize and be ejected from the orifices.
  • FIG. 2 is a high level flow diagram illustrating the printhead and printing system of the present invention.
  • FIG. 4 shows for illustrative purposes only a perspective view of an exemplary print cartridge incorporating the present invention.
  • FIG. 7 is a detailed flow diagram illustrating setup and use of the printhead of the present invention.
  • the thermal head assembly 402 can be a flexible material commonly referred to as a Tape Automated Bonding (TAB) assembly and can contain a processing driver head 410 (an example of processing driver head 120 of FIG. 1) and interconnect contact pads 412.
  • the interconnect contact pads 412 are suitably secured to the print cartridge 400, for example, by an adhesive material.
  • the contact pads 408 align with and electrically contact electrodes (not shown) on carriage 334 of FIG. 3.
  • the systematic defects can be reduced when the odd and even nozzle alignment is intentionally misaligned or offset by a predetermined amount, such as 1/600 of an inch. Text and lines printed with the predetermined amount (such as 1/600 inch offset) have cleaner edges than when printed with perfect odd/even alignment, as shown in FIG 6B. This approach works with both single pass and multipass printmodes.
  • the correction scheme of the present invention can be used as an intentional offset to correct a variety of scan axis defects.
  • Another example is using intentional bi-directional alignment offset to compensate for the effects of low velocity tails in bi-directional printmodes.
  • FIG. 8 shows a simulated ink jet printing pattern for bi-directional print modes. The first 2 columns of dots represent one pass printing in the left-to-right and right-to-left scan directions. In each case, the main drop is followed by a low velocity tail that lands "downstream" from the main drop.
