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.
Transfix Drive Slow and Transfix Drive Fast
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.
