Abstract: A method evaluates printhead position in a staggered full width array (SFWA) printhead assembly (230). The method includes selecting a first printhead configuration (232,234,236,238) for printing a first test pattern on an image receiving member, generating positional correction data for roll and stitch displacements obtained from captured image data of the first test pattern, comparing the positional correction data to at least one threshold in a displacement range, and operating at least one printhead actuator (220) in accordance with the positional correction data in response to the positional correction data exceeding at least one predetermined threshold in the displacement range.

Abstract: PROBLEM TO BE SOLVED: To correct the stitch and roll errors in an image forming device.
SOLUTION: This image forming device with a sandwich arrangement type full width array print-head assembly includes: the step of selecting a first print-head setting for printing a first test pattern on an image receiving member; the step of producing positional correction data against the displacements of the roll and stitch obtianed from the image data taken in from the first test pattern; the step of comparing the positional correction data with at least one threshold value in a displacement range; and the step of operating at least one print-head actuator in accordance with the positional correction data in response to the positional correction data, which exceeds at least one predetermined threshold value in the displacement range.
