I have a Taiwan J2101 offset press, because of long-term printing paper, when reprinting 80g/m square three open coated paper, there have been most of the delivery paper does not take the paper failure, and occasionally peeling phenomenon.
First of all, let the machine run normally. Under the condition of no pressure, the normal paper feeding, when the paper is received normally, the analysis is the reason that the pressure of the imprinting roller gripper is too high, which causes the receiving tooth not to receive the paper. Because we printed jammed paper is generally more than 300g / m square, long-term thick paper, enamel teeth and rubber mats become lighter, the rubber mat was also pressed down a little. When 80g/m2 paper is printed, the gripper's force on the paper is lighter, and in combination, the impression cylinder and the blanket cylinder generate a certain pull force on the paper, and when it is fast running, it is imprinted. The roller gripper failed to complete the transfer task, resulting in the paper can not be smoothly transferred. After adjusting the height of the rubber pad and the force of tooth decay, the problem is solved.
