Abstract: A method for customizing the graphical user interface of a multi-function device includes the steps of: (a) providing a multi-function device including a multi-function unit and a document server, where the multi-function device includes three or more built-in functions such as copying, printing, scanning, faxing, and emailing, and the multi-function unit includes a graphical user interface originally configured to display standard icons representing the built-in functions, where the user may activate the standard icons to command the multi-function device to perform the associated built-in function; (b) selecting an additional function to be available on the multi-function device; and (c) automatically adding a new icon associated with the additional function to the graphical user interface of the multi-function unit.

Abstract: A method for synchronizing the print start position for a printer carriage on an inkjet printer that includes the steps of: (a) providing an encoder signal indicative of a position of an inkjet printer carriage relative to a substrate being printed upon or a printer platen, where the encoder signal is an alternating voltage signal with an encoder signal frequency; (b) filtering and dividing the encoder signal to provide a fire pulse signal, where the fire pulse signal is an alternating voltage signal with a fire pulse signal frequency that is a multiple of the encoder signal frequency; (c) detecting a rising edge of the encoder signal preceeding a predetermined print start position of the printer carriage; (d) upon detection of the rising edge of the encoder signal in step (c), detecting a next falling edge of the fire pulse signal; (e) upon detection of the next falling edge of the fire pulse signal in step (d), detecting a count of the next rising edges of the fire pulse signal; and (f) assigning a synchron
