Testing Motor And Solenoid Resistances - Xerox ii LINXSolid Inkjet 100 Service Manual

Testing For A Shorted Motor
1. Reinstall the power supply if removed in the previous
procedure.
2. Disconnect the process motor, the Y-axis motor, X-axis motor
and the cap/wipe/purge assembly motor wiring harnesses from
the power control board.
3. Turn on the printer again to see if it does not overload now
that the motors are disconnected from the power supply.
If the power supply is functional, proceed to the procedure, "Testing
motor and solenoid resistances," below.
If the motors and solenoids are not shorted, but the power supply still
does not function, replace the power control board.

Testing Motor And Solenoid Resistances

1. Turn off the printer and disconnect the power cord.
2. With a DMM set for measuring resistance, test each motor's
windings for correct resistance (disconnected from the printer).
Refer to Table 3-2. Rotate the motor's drive shaft slightly while
taking the measurement.
