Abstract:
1. A method of operating a printing apparatus, the apparatus having a control system and an imaging member movable in a process direction, comprising: indicating a print sheet output size; and in response to the indicating, the control system operating the printing apparatus in one of a first output rate and a second output rate, the first output rate resulting from a first pitch spacing and a first velocity of the imaging member, and the second output rate resulting from a second pitch spacing and a second velocity of the imaging member; retaining setpoint data that is used by the control system to instruct the printing apparatus to operate at the first output rate and the second output rate, the setpoint data being bias voltage of a charging device that results in a particular number of output pages per minute, wherein the second output rate is within 25% of the first output rate, and the second pitch spacing is consistent with a print sheet having a length along the process direction greater than 20% of a length of a print sheet output at the first sheet output rate.
