Printing Pressure is too high

[Coolfox]

The printing pressure is too high on all units we tried all the suggestions that I read on the site from another user but everything looks ok and the problem is still there. We switched the SSK boards 1&2 checked the connection with the 5V. Are there any more suggestions? Machine SM74 Heidelberg 5 Color Press. CP 2000.

Did you check distance between blanket and impression with impression on and sheet thickness set to .10mm? With a .35mm feeler gauge you should be able to push in and pull out the gauge with heavy drag. Another thing you can try is swap back cylinder pressure motors with another unit and see if the issue stays, or follows the motor to another unit. Could also be a bad motor.

Yes, tried all that even switched motor with a new one but the problem is still there.
Technician is trying to get some guidance from Heidelberg but no luck thus far.
