Service Manual 4-45Check Misc MenuTray 3 and Tray 4 Pick/Feed MotorThis test turns on the specified motor and runs it at constant velocity for approximately 25revolutions while recording drive data. The test is the same for each motor. Requesting a test fora 525-sheet feeder that is not installed will generate an “Option Not Detected” message.R# DefinitionTypicalValue Actions0 Motor fe ripple(ticks)Reports amount of variation of the motorfollowing error over the recording interval.1 Motor fe average(ticks)Reports the motor following error averagevalue of the recording interval.2 Motor drive voltageripple (volts)Reports amount of variation of the motor drivevoltage over the recording interval.3 Motor drive voltage(volts)Reports the motor drive voltage average valueof the recording interval.4 Motor drive powerripple (watts)Reports amount of variation of the motor drivepower over the recording interval.5 Motor drive poweraverage (watts)Reports motor drive power average value overthe recording interval.Paper Path StatusThis test looks at the paper path sensors to identify if anything would prevent a page fromprinting. The front panel will display messages indicating if anything unexpected is found for: R0 =upper paper path; R1 = tray 1; R2 = tray 2; R3 = tray 3; and R4 = tray 4. The display is a string of0’s and 1’s (one digit for each sensor state) and is listed below from most significant bit to leastsignificant bit.1 = an item that needs to be corrected.0 = normalR# DefinitionTypicalValue Actions0 Upper Paper Path 6 -31 Not used, always 00 5 - Front door open0 4 - Top door open0 3 - Paper at deskew sensor0 2 - Paper at preheat exit sensor
