    My dick has been acting up lately, image jumping around 1/16th up and down from where I set it up at. Tried to tighten my cylinder grippers that didn't work pretty sure its a timing thing, At 7000 + rpms it actually registers. Help me out guys I don't have a service manual on this press so im kinda winging it. Runs envelopes okay but I go to score some 80# cover and it jumps around as well as when i run carbonless

    I thought you were a mechanic
    I would check the vacuum make and break and see if it is releasing late and holding the sheets back

    I am a mechanic but I work on ryobi's mostly so when it comes to ab dick I like to have a service manual vacuum seams fine, I'm a do a once through on the whole thing clean and lube everything see if that helps
