268,800,000 pages scurry through the press drums. If the paper tension is too tight it can rip and stop the press making a huge paper mess. Paper rolls weighing 3,500 pounds each need to be replaced regularly so the presses can continue to run uninterrupted. If the timing to switch the rolls is off, the run has to stop or slow down. But, the printer employs masters at the trade, skilled to do the right things just at the right time so production continues mostly uninterrupted.
