Tray 2, Tray 3, and Tray 4 Pick Shaft (Continued) Test is the same for each pick shaft although for Tray 2 the media path motor is used and for the 525-Sheet Feeders the corresponding pick/transport motor is used. Test determines if the shaft can be driven by the clutch, if the nudger rollers are being driven, and the pick pad/nudger roller friction. R# Definition Typical Value Actions 7 Plate lifted average MFG fe. Only Reports the peak effort required to drive the pick shaft when the nudger roller is in contact with the separator pad. A smaller value could indicate a slipping clutch, missing nudger assembly pressure spring, or glazed/dirty roller/pad. Check Fans Menu Drum Fan and Electronics Fan Test is the same for each fan. The fan is turned on fro a short time while the power is measured. Test determines if the fan is operating and turning at the expected speed. R# Definition Drum Value Elect. Value Actions 0 Max Power (watts) 2 to 12 2.25 to 6.6 1 Constant Velocity Power (watts) 0 to 8.25 0 to 10 2 Constant Velocity 0 to 5 Power Ripple (watts) 0 to 5 3 Constant Velocity Time (sec) 0 to 7 0 to 5 Reports initial power drawn by the fan at On. May indicate the condition of the windings. Reports the power drawn by the fan while running a constant velocity. Should be proportional to the final fan RPM due to the back EMF. Reports the power ripple while the fan is running at constant velocity. Could indicate a bad winding/ commutator segment. Reports the time from On until the fan reaches constant velocity. Could indicate a weak fan/fan drive or extra drag (bearings, brushes, blade). 4-24 WorkCentre C2424 Service Manual
