Y-axis Belt Slip
This test does a chase using a special sheet of preprinted media and records the y-axis following
error.

Y-axis Belt Tension
This test modifies the y-Axis servo loop so that it is unstable and oscillates. The oscillation
frequency is recorded while the drum is advanced for two revolutions. Checks for correct belt
tension and for variations in tension during operation.

Typical
Value Actions
3500 to Reports the amplitude of the first Y-axis
6900 following error peak.
3659.3 to Reports the amplitude of the maximum Y-axis
6500 FE peak after the first.
1500 to Reports the average of the Y-axis following
3000 error during the roller down portion of the
transfix operation.
Typical
Value Actions
MFG Reports the min resonant frequency over the
Only data set.
MFG Reports the max resonant frequency over the
Only data set.
MFG Reports the number of full Y-axis revs required
Only to locate the min frequency configuration.
MFG Reports the amount of additional Y-axis
Only rotation required to locate the min frequency
configuration.
