Abstract:
A method of producing a microarray, including:(A) mounting a plurality of pins in a printhead; (B) moving the printhead to a first location over a substrate so that a first subset of two or more of the pins is disposed over an active area of the substrate and a second subset of two or more of the pins is not disposed over the active area; (C) lowering the printhead and thereby allowing the first subset of pins to contact the substrate while preventing the second subset of pins from contacting the substrate; (D) moving the printhead to a second location over the substrate so that the first subset of pins is not disposed over the active area and the second subset of pins is disposed over the active area; and (E) lowering the printhead and thereby allowing the second subset of pins to contact the substrate while preventing the first subset of pins from contacting the substrate.
