    Please am having issues at my feeder..
    If the feeder picks double paper when it gets to the front lay it Stops the entire machine operation mean where it's suppose to stop only the feeder. Plz how can I resolve the issue... It's causing much waste during production...

    Please send me the picture of mid error , perhaps you have a sheet overrun accompanied by the double sheet, in this case the machine stops as a safety measure so as not to damage the machine

    Early sheet caused by extra thickness would certainly make sense, as Adil noted, machine would stop.

    By the way, why would the double sheet make it down to headstops?

    Ah, electronic double sheet detection coupled with early sheet.

    When the feed table stops, either manually, double sheet or mis-alignment, two or more pneumatic rods are fired down onto the sheet at the front stop to hold it in position.
    Sounds as though one of these isn't working, so the sheet twists a little bit and activates the overrun eye sensor.
    They should have a plastic cap on the end of the rod, which can also break off.
