Cause a): Controller is not connected to an AC power supply
Solution a): Verify that there is AC power connected to the pneumatic controller and that the voltage setting is correct for your AC voltage supply. Verify that the fuse is installed in the controller power module and that fuse rating is correct for the AC voltage used.

Cause b): Motor cable is not plugged into the controller
Solution b): Verify that the inker stepper motor is plugged into the "MOTOR" connection on the back of the Controller.
Cause c): Pins on the motor cable connector are bent or broken, causing faulty connection of the motor to the controller.
Solution c): Xandex recommends returning the inker base to the factory for replacement of the connector. If a technician with fine soldering skills is available to complete the repair, a new connector can be ordered by contacting Xandex Customer Service or by ordering online. Order part number 158-0008, 7 pin quick disconnect plug.
Cause d): Stepper motor mount has loosened or detached from the inker body.
Solution d): The motor is secured to the inker base via two screws. If they have only loosened slightly, it may be possible to re-tighten the screws to restore motorized Z function. If the motor has loosened significantly, Xandex recommends returning the inker base to the factory for service and alignment.
Cause e): Stepper motor wires have become disconnected from the motor.
Solution e): Return the inker base to Xandex for service.
Cause f): Guideway pins are bent causing the inker Z stage to bind.
Solution f): The guideway pins that align the Z movement of the inker Z stage can become bent if the unit is dropped, causing the Z stage to bind as the motor attempts to move the stage up and down. If you can feel the motor actuate when the UP and DOWN buttons are pressed but the inker does not move, this is probably the cause. The inker should be returned to Xandex for repair.
