Press Stop . Remove the Rear Cover ( PL 17.5 ). +24 VDC is measured between P/
J848 - B8 and B11 and GND.
Y N
Replace the Finisher PWB ( PL 17.13 ).
+24 VDC is measured between P/J848 - B7, B9, B10 and B12 and GND.
Y N
Check wiring between P/J848 and P/J877 for damage or poor contact. If the
check is OK, replace the Front Tamper Motor ( PL 17.10 ).
