Roland 304 diagonal register problem

i have a problem with the register b side of the first color from the pc it makes the movement without giving any error but the plate doesn't really move can someone help me?

 

Does the plate change normally?

 

I solved it by changing the pastica under the plate, the plate was sticking and not moving

 

If you want the CPL to work well, spray the pad once a week with silicone spray.
