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.

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.

Typical
Value Actions
0 to 15 Reports the average drive power level in the
foreword direction.
3 to 12 Reports the average drive power level in the
backward direction.
0.01 to Reports the time that the lower portion of the
.05 paper path drive is disconnected while the
swing arm transitions to the other drive
position.
Typical
Value Actions
4.3 to Reports the motor/drive electronics stall power.
10.85 An abnormal level may indicate a motor/motor
drive problem.
0 to 0.5 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.).
MFG Reports the average power required to move
Only 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.).
MFG Reports ripple in the power level needed to
Only 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.
MFG Same as R2 except for the other direction of
Only motion.
