3) Set the meter to the 5VDC range, and measure the voltage between
J2218-A1 (+: M12ON) and J2218-A4 (-: GND). Does it change from
about 5 V to about 0 V when the motor is rotated in service mode?
YES: Replace the transfer cleaner web motor (M12).
NO: Check the wiring from J2218A to the transfer cleaner web motor
(M12); if normal, replace the DC controller PCB.

3) Set the meter to the 24VDC range, and measure the voltage be-
tween J218-B12 (+: M3ON) and J2218-B3 (-: GND). Make copies;
does it change from about 24 V to about 0 V when the motor ro-
tates?
YES: Replace the transfer belt waste toner motor (M31).
NO: Check the wiring from J2218B to the transfer belt waste toner mo-
tor (M31); if normal, replace the DC controller PCB.
