its either tripping as a missing sheet. air holes in two forwarding fingers. or it could be that the switch that runs the the missing sheet is not working. or double sheet is tripping. double is easy set it for thicker paper. the missing sheet switch is below the feed pile. lay on your back and look up under the feed pile very bottom, where the motor is, while press is iddling. the switch is a piston that plunges in and out with every sheet. if the sheet is there the plunger does not trip the switch. if it is always moving then there is either an aiir line leak or the switch needs cleaning. I am not sure if the post 2000 models are the same if the sheet is getting torn at the front lays then you have another issue. could be a magnetic control issue.
