[pancarta.es]

Hey guys i have a seiko colorpainter 100s and the pump motor is not responding. will go into forced reverse but not responding to forced movement in the normal direction.

changed the pump cleaning station only recently and wonder if anyone can shine some light on this.
no error code appears

cheers guys keep up the great work

Got the same problem with a ColorPainter 64S. Motor works in reverse but not in the normal direction. Switched the +/- cabling hardwired and when i choose Normal direction it works but reverse not. So motor is okay. Changed the IPB1 board, problem still there…

My problem with the 64S is solved. Somehow the machine totally forgot the capping station position. Needed calibration.
