X-Axis Drive (Continued)
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.

With the drum turning at a constant velocity, the transfix roller is loaded against the drum, held for
one revolution, then raised. The velocity with which the transfix roller is moved differs for the two
tests.

motion.
Reports the width of the momentary drop in the
required drive power when the printhead
motion is being reversed. An abnormal value
may indicate an unusual amount of play in the
drive mechanism.
Actions
Reports the time from the load command to
the engine until the drum indicates contact
with the pressure roller.
Reports the average Y-axis following error
during the Roll With Transfix Roller Down
interval.
Reports the difference between the max
and min Y-axis following errors during the
Roll With Transfix Roller Down interval.
Reports the time from the unload command
to the engine until the drum indicates no
further contact.
