Abstract
The present invention is for a method for adjusting a focus of a multichannel printhead (,) for an imaging processing apparatus (,) performing the steps of establishing a home focus position and moving the printhead (,) in a first direction a predetermined number of coarse density. The printhead (,) is moved to the coarse focus position and then moved in a second direction a predetermined number of fine steps. A series of second test patches is printed on the media (,) at each of the fine steps. A fine focus position is determined by checking a fine density of each of the second test patches and selecting the fine focus position corresponding to the second test patch having a highest fine density.
