General Troubleshooting This test turns on the specified motor and runs it at constant velocity for approximately 20 revolutions while recording drive data. The test is the same for each motor. Requesting a test for tray not installed generates an "Option Not Detected" message. Tray 2, Tray 3, Tray 4, Lift Motor R# Definition Typical Value (8400) 0 Motor Peak Power 1 to 2.5 (watts) 1 Motor Average Power (watts) .25 to .55 2 Brake Average Power (watts) .10 to .20 Typical Value (8500/ 8550/8560) Actions Reports max amount of power. Reports the average motor drive power over the last half of the run interval. Reports the average motor brake power over the stop with brake interval. This test turns on the specified motor and runs it at constant velocity for approximately 25 revolutions while recording drive data. The test is the same for each motor. Requesting a test for a tray not installed generates an "Option Not Detected" message. Tray 3 and Tray 4 Pick/Feed Motor R# Definition Typical Value (8400) 0 Motor fe ripple (ticks) 1 Motor fe average (ticks) 2 Motor drive voltage ripple (volts) 3 Motor drive voltage (volts) 4 Motor drive power ripple (watts) 5 Motor drive power average (watts) Typical Value (8500/ 8550/8560) Actions Reports amount of variation of the motor following error. Reports the motor following error average value. Reports amount of variation of the motor drive voltage. Reports the motor drive voltage average value. Reports amount of variation of the motor drive power. Reports motor drive power average value. Phaser 8400/8500/8550/8560 Color Printer Service Manual 4-45
