Feeder unit

2, side baffle: control cardboard feed length, by patting the plate side size of more than 2mm.
3, paper side shoot: control the length of paper feed function, pat the plate into the side baffle, 10-20mm.
4, tailgate: control cardboard feed width, rear and tailgate spacing than cardboard width 3mm

4, printing cylinder: hanging plate alignment, firm, and left and right lateral movement to zero, the printing cylinder to clean.
5, printing roller: the gap is set in the premise of full color printing as possible under the light pressure, avoid gain produced by fine words is not clear, Leng marks the full version of anti white ghost, the printing crushing shall not exceed 0.2mm.
6, bite paper wheel: size minimum, press the edge of the paper 10mm above, the gap to high pressure 0.3-0.6mm, each color is less than 0.1mm.
