Abstract
Precise alignment between two or more nozzle plates affixed to print cartridges installed in a single carriage of an ink printer is achieved by machining datum projections on each print cartridge after its nozzle plate has been permanently secured to the print cartridge. The machined datum projections on the print cartridge contact surfaces on the carriage when the print cartridge is installed in the carriage such that the dimensions of the datums affect the position of the cartridge, and hence the nozzle plate, within the carriage.
Claims6
A method for aligning nozzle members on multiple print cartridges when said print cartridges are installed in an ink printer, said method comprising the steps of:
- providing a print cartridge having a nozzle member secured to a print cartridge body, said nozzle member having a pattern of orifices formed therein,
- said print cartridge body having one or more datums formed thereon;
- and
- altering a dimension of any of said one or more datums based upon a position of said nozzle member on said print cartridge body.
