HP Versatile Black Bulk Ink System
Separate components
Printhead Stall
This printhead stall is specially designed to hold and orient the printhead in high-performance printing systems. Its
flexible design is suitable for a variety of printhead array configurations, and is appropriate for both stationary and
moving printhead applications.
The stall's datum and alignment structure ensures accurate positioning of the printhead. This modular component
supports a 0.5-inch swath width and 600 dpi thermal inkjet printing. Printheads can be snapped in and out of the
stall for easy replacement.
Pen Driver Board
This printed circuit assembly (PCA) provides both the electrical and logical interface between the host printing system
and the printhead. This component is designed to ensure proper operation, proper firing, and protection of the
printhead. An application-specific integrated circuit (ASIC) on the PCA communicates with the host via a serial data
interface and converts configuration and print data into printhead-specific firing signals. On-board firing voltage
regulation provides consistent firing energy, independent of print density. Firing energy is programmable to ensure
optimal printhead performance and life.
Enclosed Regulator Assembly
This regulator assembly maintains the pressure and ink flow to the printhead. Because of its small size and enclosed
design, it can be mounted and incorporated easily into any design. With this regulator in place, the bulk ink supply
can be mounted some distance from the printhead, and management of backpressure and ink flow is handled
automatically.
IDS Interface Board
This electronic board mounts on the Modular Ink Supply station and enables access to ink level sensing and other
advanced ink supply features. Incorporating this board into the design increases printing system functionality. For
example, it can ensure ink supply compatibility, deliver "low ink" warnings, or enable hot swapping of ink supplies.
Modular Ink Supply Station
This component ensures easy mounting of the bulk ink supply, as well as proper electrical and mechanical connection
every time the supply is changed.
The Modular Ink Supply Station includes:
• The ISS Connector, which enables electrical connection to both the supply and the smart chip on the supply
• The Ink Seal Assembly
This convenient module includes everything you need to make all electrical and mechanical connections to the supply.
