FRU Action
1 Lower Pass Thru Sensor/
Flag Assembly Check the flag for correct operation,
binding, broken parts or interference
from the sensor cable. If incorrect,
repair as necessary. If correct, check
to make sure the lower pass thru
sensor is correctly connected to J3 on
the lower control board. Disconnect
the pass thru sensor cable and check
the voltage at J3-3. The voltage
measures approxi5 V dc. If
incorrect, check the voltage at J3-2.
The voltage measures approximately
0 V dc. If incorrect, replace the sensor
assembly. If this does not fix the
problem, replace the lower control
board.
2 High-Capacity Output
Stacker Drive belt(s), Drive
Pulleys, Belt Idlers, and Belt
Tension Springs Check to ensure the output stacker
drive belt or the failing assembly is
correctly installed on the drive pulley
and belt idler pulley. Check the belt
tension spring to make sure it is not
loose or broken. Repair as necessary.
3 Mechanical Linkage/Motor
Assembly (Upper or Lower) If the DC motor is functioning properly
check the gears, clutch and other
linkage parts for correct operation and
any signs of wear, broken gear teeth
or damaged parts. If incorrect, replace
the mechanical linkage assembly/DC
Motor Assembly.
