How to fix DJ Transport not moving

transport is stuck and not moving back and forth

Check Sensor

-- check the flag to see if it goes in the sensors or not

-- Turn the transport off then move the middle screw (long rod in middle transport)

-- Turn it back on and see if the problem still exist

Check PLC ( Programmable Logic Control)

-- Turn on transport and move the middle screw to see if it moves

--- if it moves, then PLC is bad or the Couplers are bad or the wirings are bad

----if Couplers move and middle screw doesn't move then Couplers either loose or went bad

----if PLC doesn't turn on, need to replace PLC

Check location for sunlight to see if sunlight is hitting the sensors, that can cause the sensors to misread.
