Patent ID: 8057005

Claim:
A method of adjusting an ink jet imaging device, the method comprising: identifying a drop placement position on a rotating image receiving member of an ink jet imaging device for an ink drop ejected by at least one ink jet of a print head, the rotating image receiving member rotating in a process direction; comparing the identified drop placement position for the ink drop ejected by the at least one ink jet on the rotating image receiving member to a default drop placement position on the rotating image receiving member for the at least one ink jet to determine a difference in drop placement position between the identified drop placement position on the rotating image receiving member and the default drop placement position of the at least one ink jet; calculating a difference in position along the process direction of the rotating image receiving member between the identified drop placement position of the ink drop ejected by the at least one ink jet on the rotating image receiving member and the default drop placement position of the at least one ink jet, the difference in position along the process direction of the rotating image receiving member corresponding to a process direction displacement for ink drops ejected by the at least one ink jet onto the rotating image receiving member; comparing the process direction displacement for ink drops ejected by the at least one ink jet onto the rotating image receiving member to a threshold value to determine whether a mass of the ink drop ejected by the at least one ink jet onto the rotating image receiving member is within tolerance limits for an ink drop mass corresponding to the default drop placement position for the at least one ink jet; and adjusting an amplitude of a voltage of an ink jet driving signal for the at least one ink jet in response to the process direction displacement mass of the ink drop ejected onto the rotating image receiving member by the at least one ink jet not being within the tolerance limits.
