1. Fully enclosed ink stack, tighter sealing, long-lasting moisturizing, automatic cleaning, cleaner and simpler printing.

2. 4.5L large capacity ink cartridge, paired with 4 500ml secondary float buffer ink cartridges; Automatic alarm for main ink cartridge liquid level detection

3. Servo motor, 400W motor, with high driving force, faster speed, and smoother operation.

4. Anti collision small frame: The height of the nozzle can be adjusted according to different printing consumables, and anti-collision devices can be added at both ends to provide more comprehensive safety protection for the nozzle.

5. Expansion type self-locking synchronous wheel structure ensures uniform step accuracy and smaller errors

6. Inflatable shaft type rewinding system: This rewinding system can retract up to 1000 meters of paper and has the characteristics of high load-bearing capacity, long service life, uniform force distribution during paper feeding and unloading, and short inflation and deflation operation time. The unique swing rod in the roll up and roll up system ensures even force distribution on the paper during the entire printing process, resulting in a smooth and compact roll up.
