If incorrect, check the autoconnect system for any problems. 
+24 V dc must come from the base printer through the autoconnect 
system to the high-capacity input for the high-capacity feeder to be 
recognized. If the voltage is correct, check the voltages at J11-3(red) 
and J11-4(red). The voltages m24 V dc. If correct, replace 
the high-capacity feeder option system board. If incorrect, disconnect 
J8 from the system board and measure the voltages again. If 
incorrect, check the LVPS cable and the AC internal wiring from the 
input appliance receptacle. If incorrect, replace as necessary. If 
correct, replace the LVPS. If the voltages are correct, check the 
stepper motor for shorts from the motor housing to each pin on the 
motor connector. If you find a short between any pin and the motor 
housing, replace the motor assembly. If no shorts are found, replace 
the high-capacity feeder option control board. 

Check the voltage at J9-1 (light blue). The voltage measures 
approxi24 V dc. If incorrect, disconnect the cable at J9 and 
check the voltage again. If the voltage continues to be incorrect, 
replace the high-capacity feeder option system board. If the voltage 
measures correctly, check the cable. If the cable is damaged, replace 
as necessary. If no problem is found with the cable, replace the high-
capacity feeder option control board.
