QM46 - plate not contacting blanket

[dagoof]

Was hoping someone could point in the direction of how to solve a problem that's cropped up on our QM - suddenly the plate cylinder on PU2 doesn't seem to be making contact with the blanket.

What mechanisms would cause this?

check the thickness of your plate first,maybe is less thick form before

Did you just replace the blanket ? If so, check the thickness
