Method For Adjusting Transfer Current In An Image Transfer Machine

A method for controlling the magnitude of an electrical signal driving a transfer device in a printing machine that is operable to transfer a medium onto a sheet, a method for, comprising:

• assigning a magnitude to the electrical signal that drives the transfer device, the assigned magnitude being one of a high, a medium, and a low transfer stress levels;
• comparing a pre-determined priority value for each of a plurality of operating parameters of the printing machine to a corresponding pre-determined threshold value corresponding to at least one of a change in stress level from low to medium, and a change in stress level from medium to high.
• evaluating only the operating parameters of the printing machine having a pre-determined priority value that equals or exceeds the corresponding pre-determined threshold value;
• selecting one of the at least two transfer stress levels for at least one of the evaluated operating parameters;
• and
• applying the assigned magnitude of the electrical signal to the transfer device, the assigned magnitude corresponding to the selected stress level.
