Tray 1 Pick Shaft (Continued)
Runs the media path drive train and engages the Tray 1 pick solenoid on the fly. The pick shaft
goes through 2 full revolutions while drive requirements are determined.

Value Actions
MFG Reports the average MP fe immediately
Only following the pick shaft engagement.
A higher value of R2 could indicate extra
friction between the cams and the lift plate
followers (wear, contamination, etc.), as well as
high lift plate spring tension or higher shaft
bearing drag. If the missing tooth gear did not
kick forward and engage, this value would be
unchanged from R0.
MFG Reports the minimum MP fe value at the
Only transition point between breaking separator
pad contact and the continued depression of
the lift plate.
Value reflects the effort needed to rotate the
pick shaft and compress the lift spring. A
higher value of R3 could show higher cam/
bearing friction and/or lift plate spring strength.
MFG Reports the average MP fe while the pick roller
Only is contacting the separator pad. This value
should reflect the coefficient of friction between
the separator pad and the pick roller. This
value may be effected by contamination or
glazing.
MFG Reports the peak MP fe during the interval
Only when the pick cams are depressing the lift
plate.
A higher value here could indicate issues with
the cam surfaces or the spring compression
force.
MFG Reports the average MP fe following the re
Only latching of the missing tooth gear.
This value should be the same as R0 if the
missing tooth gear successfully relatched.
