Service Manual 4-37Check Drum Menu4 Lift Contact Time(sec)Reports the interval from the motor start timeuntil the required lift power starts to increasedue to the initial contact with the nudger rollerassembly.5 Lift Time (sec) Reports the interval from the motor start timeuntil plate lifted is indicated.6 Stall Power (watts) Reports the average stall power during theoverlifting intervalY-axis EncoderUses the sine and cosine sum data to determine the characteristics of the encoder disk andencoder sensors.R# DefinitionTypicalValue Actions0 Sin Sum DataAmplitude (sin sumunits)-11000 to350000Reports difference between the max and minSin Sum average amplitude values.1 Cosine Sum DataAmplitude (cosinesum units)300000 to500000Reports difference between the max and minCosine Sum average amplitude values.2 Sin Sum Data Offset(sin sum units)150000 to800000Reports average of the max and min Sin Sumaverage amplitude values.3 Cosine Sum DataOffset (cosine sumunits)90000 to450000Reports average of the max and min CosineSum average amplitude values.4 Home Notch DepthRatio (none)0 to 13 Reports the ratio between the notch bottomamplitude and the max amplitude value asreflected in the Sin Sum data.5 Home Notch Width(sec)50 to 90 Reports the width of the Home notch at 99%full depth as reflected in the Sin Sum data.6 Home NotchSymmetry (none)250 to550Reports the ratio of the Home notch widthsections as bisected by a vertical from thenotch min as reflected in the Sin Sum data.Tray 2, Tray 3, Tray 4, Lift Plate Drive (Continued)This test raises the lift plate to verify motion and sensor operation. If the test is requested for a525-sheet feeder that is not installed, an “Option Not Detected” message is generated.R# DefinitionTypicalValue Actions
