    Hey guys and dolls, I'm having an issue with my numbering impression on a 2005 speedmaster 52/2 colour. The thing is if you misfeed a sheet the printing units come off impression but the numbering unit continues to click over a couple of numbers before the impression and the cam stop, which means you have to reset the number everytime.
    Has anybody out there had this problem and if so how do I fix it.

    cheers

    I don't know the specifics of your machine, but we do numbering on two different machines. There has to be a way for you to set the cam to tell the wheels to stop, just before or after the press gets a misfeed. In our case if the cam is off, it will actuate 10 numbers before it stops the machine. If the cam is too early it has to wait till one revolution to stop the wheels, too late and it will fire a few before stopping. Hope this helps
