Abstract:
A method for synchronizing the print start position for a printer carriage on an inkjet printer comprising the steps of:(a) providing an encoder signal indicative of a position of an inkjet printer carriage relative to one of a substrate being printed upon and a printer platen; (b) filtering the encoder signal to provide a filtered encoder signal; (c) detecting an activation in the encoder signal preceding a predetermined print start position of the printer carriage relative to the one of the substrate being printed upon and the printer platen; (d) upon detection of the activation in the of the encoder signal in step (c), detecting a next deactivation of the filtered encoder signal; (e) upon detecting the next deactivation of the filtered encoder signal in step (d), detecting a count of the next activations of the filtered encoder signal; and (f) assigning a synchronized print start position at an end of the count.
