Product Name: 7301-D1 Type 2x Secondary Ink Cartridge (Without Valve | 7-In 1 Out | Top Interface Customizable)
Product Overview:
The 7301-D1 secondary ink cartridge is a 2-fold capacity secondary ink cartridge designed specifically for industrial inkjet ink supply systems. It features a straight through structure without a valve and comes standard with a 7-in and 1-out configuration. It plays a critical role in buffering and stabilizing ink delivery in negative pressure ink supply systems. Compared to the standard 1x ink cartridge, the 2x capacity chamber can store more ink, effectively reducing the frequency of ink replenishment and suitable for high load continuous production scenarios. The product is compatible with various industrial nozzles and negative pressure ink supply systems, and the top interface supports flexible selection from 1 to 9 ports, meeting the needs of different ink path diversion and pipeline layout.
Interface configuration and customization options:
The optional range for the number of top interfaces of this product is 1 to 9 ports, which can be specified according to the actual ink path requirements when placing an order. The standard factory configuration is 7 in and 1 out (7 ink inlet and 1 ink outlet), supporting one to many nozzle configurations. If you need other combinations of import/export quantities or special interface specifications, please contact technical support to confirm the feasibility of customization.
Suitable for industrial nozzles (full series):
This product is suitable for the following types of industrial nozzles, compatible with various configurations such as one to one, one to two, and one to four negative pressure ink supply systems:
Ricoh: G5, G5i, G6, MH series
Seiko: SPT series (255/510/1020, etc.)
Kyocera: KJ4 series
Epson: I3200, DX5, DX7, etc

Xaar: 128, 200, 1002, etc
Polaris: PQ512, 15PL/35PL, etc
Canon: Industrial print head series
Mutoh and various industrial grade piezoelectric nozzles
Core features:
2x capacity design: Compared to 1x ink cartridge storage capacity, it doubles the continuous printing time and reduces downtime for ink replenishment;
Non valve straight through structure: reduces ink path resistance and fault points, easy maintenance, suitable for ink supply solutions that rely on system negative pressure control;
7-in-1-out standard configuration: multiple ink inlets converge to a single ink outlet, suitable for one to multiple nozzle layouts;
The top interface is flexible and optional: 1-9 ports can be selected as needed to reduce the cost of adapter adaptation;
Negative pressure system compatibility: It can be used in conjunction with mainstream negative pressure ink supply solutions such as vacuum generator negative pressure, diaphragm pump negative pressure, and positive negative pressure circulation.
