The 7501-D6 single column transparent secondary ink cartridge is designed specifically for industrial grade One Pass high-speed inkjet printing and multi nozzle centralized ink supply scenarios. The product adopts a single column transparent structure design, with a capacity of 138mL, integrated with 2 independent outlets, equipped with negative pressure port, ink inlet and ink outlet (with a unified insertion tube specification of 6 × 4), and equipped with a manual control valve, supporting stable and accurate secondary ink supply management for multiple sets of nozzles.
Efficient ink supply ensures high-speed continuous printing
One pass printing requires a fixed nozzle and a single pass of the medium to complete full frame imaging, with extremely high demands on the instantaneous flow rate and continuous stability of the ink supply system. The 7501-D6 ink cartridge effectively buffers pressure fluctuations in the main ink path, ensuring sufficient and stable ink supply for high flow industrial nozzles during high-speed continuous operation, and avoiding ink breakage, ink flying, or oblique spraying problems caused by insufficient ink supply.
Transparent structure, real-time monitoring at a glance
Adopting a transparent material shell design, operators can intuitively observe the remaining ink level and flow status inside the ink cartridge (138mL capacity is clear and visible), which facilitates timely ink replenishment, troubleshooting of ink path bubbles or blockages, and reduces equipment maintenance difficulty and shutdown risks.
Negative pressure port+manual valve, flexible and precise control
The product integrates a negative pressure interface and supports precise ink pressure regulation through an external negative pressure system. When combined with a manual control valve, it can flexibly intervene in the opening and closing of the ink circuit, facilitating equipment debugging, ink replacement, or ink isolation operations during maintenance, and adapting to diverse production conditions.
Standard 6 × 4 intubation, easy to install
The ink inlet, ink outlet, and negative pressure outlet are uniformly equipped with 6 × 4 specification insertion ports, and the standardized design greatly reduces installation complexity, facilitates quick replacement and pipeline layout, while reducing the types of spare parts and lowering inventory pressure.
Widely compatible with mainstream industrial nozzles
The product has excellent compatibility and is compatible with Ricoh G5/G6, Epson T3200, Seiko 1024 series, as well as the full range of industrial grade nozzles from Kyocera, Konica, Toshiba, Sear, etc. It can flexibly match the ink supply needs of different equipment manufacturers and end users.
Support non-standard customization
In addition to the standard 138mL capacity and 6 × 4 intubation specifications, our company supports non-standard customization of interface types, capacity specifications, pipe diameter sizes, etc., to meet diverse equipment matching needs.
