Product Details
Specifications
Function: Monitors and regulates negative pressure within the ink supply system, ensuring stable ink suction and preventing nozzle flooding or air intrusion.
Application: Maintains consistent vacuum levels (e.g., color: –3.5 to –4.2 kPa; white: –3.8 to –4.5 kPa) for printheads. The board interacts with pressure sensors and pumps to activate control actions when pressure deviates.
Typical Use: Compatible across various Allwin series print systems—commonly used with printhead assemblies in solvent, eco-solvent, and UV RTR applications.
Highlights
Essential for Print Stability: Crucial for preserving consistent negative pressure in the ink path, which is vital for proper print quality and nozzle health.
OEM-Level Reliability: Designed for seamless integration with Allwin hardware—provides accurate pressure control to avoid common issues like ink drips or nozzle misfires.
Compact and Precise: Typically mounted inside the printer’s carriage or control box to directly monitor and adjust ink supply conditions in real time.
Applications & Uses
Ink Supply Regulation: Ensures negative pressure remains within optimal thresholds to prevent over- or under-suction.
Maintenance & Troubleshooting: Essential replacement when printers display pressure errors or experience maintenance-related interruptions.
Hardware Compatibility: Works with printers equipped with negative-pressure ink systems—like Allwin RTR, Konica-head models, and other industrial jet equipment.
