ink supply part type
Negative pressure system
Negative pressure system products from JOHOPE. Confirm compatibility by printer model, part number, dimensions, connector and ink chemistry before quotation.
A negative pressure system holds a slight vacuum on the ink supply so that ink stays controlled at the nozzle plate instead of flooding or dripping between jetting cycles. It is used where the ink supply sits above the printhead, or wherever stable pressure at the nozzles is needed for consistent jetting.
Negative pressure is delivered as an assembly rather than as a single part. Our selection includes complete negative pressure systems for large-format digital inkjet printers, together with the components used alongside them: negative pressure meters, the KHF-5V7K negative board and OMRON LY2N-J 24VDC relays.
Browse the components below. Because these are system-level parts, send your printer model, the printhead it runs and the current configuration so that the correct combination can be identified before quotation.

FAQ
What is a negative pressure system in an inkjet printer?
A negative pressure system holds a slight vacuum on the ink supply so that ink stays controlled at the nozzle plate instead of flooding or dripping between jetting cycles. It is used where the ink supply sits above the printhead or where stable meniscus control is needed for consistent jetting.
What is included in a negative pressure system?
A negative pressure setup is an assembly rather than a single part, typically combining a controller or regulator with the sensing and pumping elements that maintain the set vacuum. The parts listed on this page are the components JOHOPE holds for these systems.
How do I confirm which negative pressure components my printer needs?
Because these are system-level components, the printer model and the existing configuration matter more than a single part number. Send JOHOPE your machine model, the printhead it runs and photographs or part numbers of the current assembly, and the match is reviewed before any quotation.
