1. Adopt industrial-grade integrated appearance frame: the machine runs more stably.
2. The overall increase and width of the beam: the strength is higher, and the machine runs more smoothly.
3. Optimize the arrangement of the latest trolley bottom plate: while increasing the printing speed, the printing quality is further improved.
4. Encryption of the pressure wheel + damping mechanism of the front paper guide roller: make the stepping operation more stable, the paper feeding more accurate, and the printing accuracy higher.
