The flow passage branch unit distributes ink from the ink from the ink cartridges (8) to the supply pumps (12). Ink distribution is done with the joint tubes.

The eight ink tubes [A] from the ink cartridges go into the flow passage branch unit [B] and are distributed to twelve ink tubes [D] via the joint tubes [C], and then connect to the supply pumps.

The connection paths of the ink tubes and joint tubes differ depending on the combination of ink. When there are unused paths, close them with the sealing caps [E].

Example: 4-color machine

Piping Patterns of Ink Tubes/Joint Tubes

The following patterns of ink combination can be used in this machine.

  • 4C: Uses two cartridges of each of cyan, magenta, yellow and black.
  • 4C+W: Uses one cartridge of each of cyan, magenta, yellow and black, and four cartridges of white.

The piping patterns of ink tubes/joint tubes differ depending on the ink combination. The machine is configured using the 4C pattern in the factory. If the customer is going to use the 4C+W pattern, the piping pattern must be changed during machine installation.
