    hi ,
    im having problems with the pump motor of my roland cj 500 eco sol. practically, if i put on the printer, it tries to suck ink, the motor rotates then it stops and screems. i disconnected it from the pump, and realised that it rotates and later it stop rotating.
    can it be some electrical problems on the mother board? can it be problems with the pump DRIVER on the mother board?
    help me please if any body has an idea.
    this happened after i changed the capping system, the heads and the pump.
