7 Plate lifted average
fe.
MFG
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.
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.

0 Max Power (watts) 2 to 12 2.25 to
6.6
Reports initial power drawn by
the fan at On.
May indicate the condition of the
windings.
1 Constant Velocity
Power (watts)
0 to 8.25 0 to 10 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.
2 Constant Velocity
Power Ripple (watts)
0 to 5 0 to 5 Reports the power ripple while
the fan is running at constant
velocity.
Could indicate a bad winding/
commutator segment.
3 Constant Velocity
Time (sec)
0 to 7 0 to 5 Reports the time from On until
the fan reaches constant velocity.
Could indicate a weak fan/fan
drive or extra drag (bearings,
brushes, blade).
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.
