Full-Loop Ink Supply and Return
The supply pump, printhead feed/return ports and return pump form a complete path, reducing stagnant areas in the ink system.

The S series uses FCS full-loop ink circulation to manage the complete supply/return path. Combined with pressure feedback at both printhead ends and dual-pump PID control, it provides a system foundation for multi-orientation and moving printing.
360° denotes multi-orientation solution capability; validate ink, printheads, motion paths and curing positions against actual operating conditions.

01 / ADVANTAGES
The Complete Ink Path Can Be Measured and Controlled
FCS manages the ink supply/return path from the tank through the printhead and back to the tank.
Dual-End Pressure Feedback
Measure inlet and return pressure near the printhead, and adjust the two pumps using inlet pressure and the target pressure differential respectively.
Multi-Orientation Solutions
Validate side printing, upward printing and robotic moving printing item by item against orientation and dynamic pressure.
02 / SYSTEM
Full-Loop Circulation from Tank to Printhead
Full-loop circulation describes the system-level supply/return path; circulation behind the nozzles depends on the specific printhead structure.
01Ink Tank and Supply Pump
Provide continuous ink supply to the printhead.
02Printhead Feed/Return Ports
Measure pressure at two points near the printhead.
03Return Pump and Return Flow
Adjust return flow according to the target pressure differential and return ink to the tank.
The application focus differs from SL series CCS: S series FCS focuses on the complete supply/return path and multiple orientations; SL series CCS focuses on recirculation near the printhead and nozzle condition.
03 / MODEL SELECTION
Four models selected by width and speed
Check print width, resolution, target speed and printing distance together.
| Model | printhead | Print Width | Native Resolution | Speed | Reference Throw Distance |
|---|---|---|---|---|---|
| S1 | CF6R | 53.95 mm | 600 npi | 30 m/min | 25 mm |
| S2 | RC1536 | 108.3 mm | 360 npi | 157 m/min | 50 mm |
| S3 | Xaar 2002 | 70.5 mm | 720 npi | 75 m/min | 15 mm |
| S4 | G5F | 54.1 mm | 600 npi | 76 m/min | 8 mm |
Speeds are stated for printheads at native resolution × native resolution; throw distance and actual output are subject to sample testing.
04 / APPLICATIONS
Application Scenarios
Determine the system configuration from the printing objective, material and actual site speed.
Packaging sides and angled faces
Assess the negative-pressure operating window for side and angled printing through workpiece positioning and printing-distance calibration.
Robotic Multi-Surface Printing
Check acceleration, deceleration, hose drag and trigger timing along the motion path.
High-pigment white ink
Continuous recirculation reduces tubing sedimentation risk; tank agitation, filtration and ink stability still require validation.
Wide or high-speed lines
Configure multiple-printhead stitching or overlapping according to flow rate, pressure differential and return-flow capacity.
05 / CONFIGURATION
From sample to line configuration
Let actual samples and operating conditions determine the printhead, ink, mounting and control solution.
Provide this information.
- Material sample and ink requirements
- Print content, print width and target speed
- Printhead orientation and motion path
- Installation of space, hose length and interface
Focus Validation
- Feed/return pressure at different orientations
- Print placement at maximum speed and during acceleration/deceleration
- Printing quality during extended operation with the target ink
- First-item results after shutdown and restart
System capabilities can be combined for the project; printheads, ink and optional functions are subject to the final delivery list and actual testing.
