Ink Supply Mechanism, Valve Mechanism | Epson 7600, 9600 specification

EPSON Stylus Pro 7600/9600

Revision A

2.2.4 Ink Supply Mechanism

Stylus Pro 7600/9600 is so constructed that the 7 cartridges for different colors are installed in the respective ink holders (I/H) in the left area of the printer. A projection and unique marking are placed on each color ink cartridge case to prevent wrong insertion so that the correct cartridge is inserted in the right direction.

Explanation of valve mechanism mounted on the cartridge

The valve automatically opens and closes when the ink cartridge is mounted and removed.

Figure 2-16. Valve Mechanism

The ink flow is as shown below.

Each color's ink cartridge → Each color's I/H (Ink Holder) → Each color's ink tube → Each color's head dumper (carriage) → Print Heads

The information in EEPROM of each color ink cartridge is sent through the CSIC Relay Board in each ink holder and stored in memory on the CSIC Board.

The CSIC Board stores various pieces of information, such as ink colors and remaining amount of ink. (Refer to “Ink information menu (p.69)”)
