Abstract:
1. A method of adjusting an imaging device, the method comprising: ejecting a first line of fluid drops across a rotating image receiving member in a cross-process direction; ejecting a second line of fluid drops across the rotating image receiving member in the cross-process direction, the second line being generated to be placed on the first line of fluid drops; identifying a distance between a first portion of the first line of fluid drops and a first portion of the second line of fluid drops; storing the identified distance in association with a printhead that ejected the fluid drops in the first portion of the first line of fluid drops and the first portion of the second line of fluid drops; cleaning a surface of the rotating image receiving member; ejecting a third line of fluid drops across the rotating image receiving member in the cross-process direction; ejecting a fourth line of fluid drops across the rotating image receiving member in the cross-process direction, the fourth line being generated to be placed on the third line of fluid drops; identifying a distance between a first portion of the third line of fluid drops and a first portion of the fourth line of fluid drops; comparing the identified distance between the first portions of the third line and the fourth line to the identified distance stored in association with the printhead that ejected the fluid drops in the first portion of the third line of fluid drops and the first portion of the fourth line of fluid drops; and modifying a printer parameter in response to the identified distance exceeding the identified distance stored in association with the printhead that ejected the fluid drops in the first portion of the third line of fluid drops and the first portion of the fourth line of fluid drops by a predetermined amount.
