Abstract
To accurately position printheads (C,M,Y,K) of an inkjet printer in the capping area of their service station ( ), the position of service station insert members (e.g. K) is determined by an optical sensor ( ) detecting a through hole ( K) in the cartridge lid ( ), and the separation (j) of the optical sensor and the printheads (e.g. K) is precisely determined. The separation (j) is determined by using the printhead nozzles to print lines ( ) in the directions of the scan and media axes, scanning the lines with the optical sensor ( ), and calculating from the results the separation (j). The results of locating the four reference holes ( C, M, Y, K) of the service station insert members may be averaged.
