The Ink Delivery System (IDS) delivers ink under pressure from the large capacity off-axis Ink Cartridges via permanently connected tubes to the high throughput Printheads.

The IDS consists of six major subsystems:

-The Ink Cartridges.
-The Ink Supply Station (ISS).
-The Tubes System.
-The Printheads.
-The Air Pressurization System (APS).
-The Leak Detect System (LDS).
