General Troubleshooting 4-43
Y-axis Belt Slip
This test does a chase using a special sheet of preprinted media and records the y-axis following
error.
R# Definition
Typical
Value Actions
0 Initial Peak Y-axis
FE (mpts)
3500 to
6900
Reports the amplitude of the first Y-axis
following error peak.
1 Max Following Peak
Y-axis FE (mpts)
3659.3 to
6500
Reports the amplitude of the maximum Y-axis
FE peak after the first.
2 Average Y-axis FE
(mpts)
1500 to
3000
Reports the average of the Y-axis following
error during the roller down portion of the
transfix operation.
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.

Value Actions
0 Min Resonant
Frequency (hz)
MFG
Only
Reports the min resonant frequency over the
data set.
1 Max Resonant
Frequency (hz)
MFG
Only
Reports the max resonant frequency over the
data set.
2 Min Resonant
Frequency Revs
(revs)
MFG
Only
Reports the number of full Y-axis revs required
to locate the min frequency configuration.
3 Min Resonant
Frequency Angle
(deg)
MFG
Only
Reports the amount of additional Y-axis
rotation required to locate the min frequency
configuration.
