Paper Path Drive This test moves the gear train in one direction while capturing data, does a reversal to capture reversal transient data, and then operates in the other direction. R# Definition Typical Value Actions 0 CW Average Power 0 to 15 (watts) 1 CCW Average Power (watts) 3 to 12 2 Swing Arm 0.01 to Transition Time (sec) .05 Reports the average drive power level in the foreword direction. Reports the average drive power level in the backward direction. Reports the time that the lower portion of the paper path drive is disconnected while the swing arm transitions to the other drive position. X-Axis Drive This test drives the X-Axis motor in each directions until the printhead stalls into the stops, and then moves the printhead into the clear and performs an on-the-fly reversal. The power profile is used to confirm operational goals. R# Definition Typical Value Actions 0 Right Stall Power Level (watts) 4.3 to 10.85 1 Left Right Distance 0 to 0.5 (in) 2 Right Left Traverse MFG Average Power Only Level (watts) 3 Right Left Traverse MFG Power Ripple (watts) Only 4 4-36 Left Right Traverse Power Average Level (watts) MFG Only Reports the motor/drive electronics stall power. An abnormal level may indicate a motor/motor drive problem. Reports the distance between the left and right stall points. An abnormal value may indicate an problem that restricts the range of motion (pinched cable, etc.). Reports the average power required to move the printhead from the right hard stop to the left hard stop. An abnormal value may indicate a problem with the lead screw or printhead bearings (lubrication, etc.). Reports ripple in the power level needed to move the printhead from the right hard stop to the left hard stop. An abnormal value may indicate a problem with roughness in the drive mechanism or an interference with the printhead motion. Same as R2 except for the other direction of motion.
