Adjusting The Bid Engage And Disengage Angle - HP Indigo press 3050 User Manual

Adjusting the BID engage and disengage angle

During printing the BID unit presses against the PIP, and then disengages. The BID to PIP
engagement duration must be sufficient to cover the maximum image length (437 mm,
17.2 inches). Each BID unit should be adjusted individually because the BID angular
position varies from one unit to another other. The BID engage angle must allow for the
image leading edge to be at 10 mm (0.39 inch) of the sheet's leading edge. The BID
disengage angle should allow the image trailing edge to be at 447 mm (17.6 inches) of the
sheet's leading edge.
