At high speed, 120 sheets per minute, and the maximum paper feed 1500 sheets. In order to improve the operation efficiency in batch print, the number of sheets fed is increased to 1500. The standard computer interface is equipped with a standard print parallel port and a bidirectional parallel port conforming to the IEEE 1284 specification, so the print quality is better, and the cost of each print is only 10, which is low. Driven by DC motor, when printing at high speed, the machine body is stable and overprinter is accurate. The newly designed operation panel is more convenient to operate. The printing area can be adjusted by 0.5mm up and down, left and right, and any manuscript, newspaper clippings and thick book origami can be easily handled. And the position of the original on the scanning table can be adjusted as needed, without limitation. The new plate unloading mechanism adopts a special waste plate recycling rod with a handle, which is not only clean and hygienic, but also convenient and simple to place. Simple operation, simple plate making, fully automatic printing program, simple and clear arrangement of buttons on the operation panel, and one person can control multiple machines.
