a, the connector is not secure, generally because the interface tape of Logistics Waybills Paper is too short, resulting in too much space left at both ends of the joint.

b. The paper on both sides of the paper is not evenly pulled, one side is slack and the other side is tight, because the paper is not connected correctly.

c. When printing on computer paper, you should not blindly ask for it. When the base paper is cut, mark it on the joint of the paper roll. Then the printer should slow down the printing speed at the joint to avoid the paper break. The situation arises.

d. Sometimes the two layers of Courier Waybill paper inside and outside are stuck together, which directly causes the printing process to interrupt the paper phenomenon. This situation is still relatively common, mainly because the paper roll joint tape is too long and the excess tape is stuck.

e. If the offset press can determine the joint of the paper roll by itself, it can be connected with a relatively dark color tape to improve the recognition rate of the joint and reduce the running speed of the printing machine to avoid problems.
