4-42 Phaser 8400 Color PrinterCheck Motors Menu7 Releasing Amplitude(mpts)-45 to 0 Reports the magnitude of the reaction of thedrum to the blade withdrawal (see R3).Drum Maintenance ContactThis test uses the drum servo error signal to indicate when the drum is contacted by the rollerblade.R# DefinitionTypicalValue Actions0 Initial ContactPosition (pm motorcounts)Reports the distance the pm motor was moved(raising the dm unit), before a Y-axis reactionwas detected. Shows that the dm is raising,provides blade/drum gap information.Y-Axis MotorThis test turns on the Y-axis motor and runs it very slowly for one revolution.R# DefinitionTypicalValue Actions0 Motor fe ripple(ticks)0.08 to0.60Reports amount of variation of the motorfollowing error over the recording interval.1 Motor fe average(ticks)0.5 to 0.7 Reports the motor following error averagevalue of the recording interval.2 Motor drive voltageripple (volts)0.34 to1.3Reports amount of variation of the motor drivevoltage over the recording interval.3 Motor drive voltage(volts)-1.4 to-0.8Reports average value of motor drive voltageover the recording interval.4 Motor drive powerripple (watts).0.25 to1.8Reports variation of motor drive power over therecording interval.5 Motor drive poweraverage (watts)1.25 to2.6Reports average value of motor drive powerover the recording interval.Stripper Contact (Continued)This test holds the drum stationary while the stripper solenoid is activated and released. Thedrum servo error signal illustrates activation/deactivation timing and how strongly the drum wascontacted by the blade.R# DefinitionTypicalValue Actions
