HP 510 Inkjet Large Format CH336A#B1K manual Ink Delivery System IDS, Ink Supply Station ISS

Functional Overview

Ink Delivery System (IDS)

The Ink Delivery System (IDS) delivers ink from the off-axis Ink Cartridges via permanently connected tubes to the high throughput Printheads for the HP DesignJet 500/510/800 Series Printers

The IDS consists of two major subsystems:

„The Ink Supply Station (ISS).

„The Tubes Assembly.

Ink Supply Station (ISS)

In the Printer, the Ink Cartridges reside inside the Ink Supply Station (ISS). The ISS is situated on the right hand side of the Printer and will be able to handle 69cc capacity Ink Cartridges (for all colors). The ISS is the part of the Printer that provides the pressure to pump the ink from the Ink Cartridges to the Printheads. It has a mechanism for each one of the four Ink Cartridges. Each mechanism consists of a spring that pulls from a rocker that pushes the lifter that pressurizes the bongo. There is a camshaft, which is driven by an electric motor, that moves the four lifters down pressing on the rocker. The ISS also has sensors which can detect when the pump chamber is empty and needs to be refilled (by pushing down the lifters).
