R4-SF/WF Series
RICOH GEN4 printhead architecture
R4-SF/WF defines the best printhead architecture on high resolution and high speed inkjet technology. It is equipped with the latest RICOH GEN4 printheads which output 6 pico liter variable dot grayscale and 1200 dpi with 30 kHz jetting frequency. It is widely recognized as the best quality printhead for the ever-increasing production demand nowadays in terms of speed and quality. Moreover, upgradability is available on R4-SF/WF up to 32 printheads with 4 staggered that can achieve a real production speed of 96 sqm/hr for 4 pass at 1200 x 600 dpi.
True industrial build flatbed with vacuum table
Built on a solid steel platform, R4-SF/WF features a unique, linear motor driven vacuum bed for highly accurate dot placement. The flatbed architecture can print on rigid media up to five centimeters (2”) thick. Geared up by a vacuum table to hold all types of materials perfectly in place to ensure perfect registration on rigid and flexible materials. A true flatbed means accuracy for perfection.
Intelligent two stages heating ink supply system
The intelligent two stages heating ink supply system on every R4-SF/WF series ensures the ink is at the perfect operational temperature and viscosity before printing. Located at the sub-ink tank and printhead, the system also ensures normal operation for cold and icy environment.
Active negative pressure ink system
The active negative pressure ink system ensures high stability of ink supply. Operator can easily monitor the system through digital display gauges to control active negative pressure. Additionally, the bulk and waste ink tank are installed with level sensors to alarm ink refill and overflow signal.
Single Belt Tension System
GUNSJET uses a true flatbed table with linear motion to control movement and ensure perfect registration on rigid and flexible materials while it delivers the best True Flatbed capabilities with a vacuum table to hold all types of materials perfectly in place for high quality printing every time.
