When filling 4-color ink set
Two paths of the same color are linked shortly after the cartridge valves.
Normally the valve of 1 cartridge per color is opened by toggle switching, supplying ink to
a 2-nozzle row.
Thereafter, the cartridge on the side with the open valve is referred to as the control
cartridge, while the other is referred to as the sub cartridge.
Longer consecutive drawing time than conventional products and replacement of
cartridges during the drawing are allowed by toggle switching of 2 cartridges for 1 supply
path.

When filling any ink set
other than 4- color ink set
(6-color ink set, 6-color +
white ink set, 7-color ink set,
8-color ink set)
1 cartridge is connected to a 1-nozzle row. No toggle is switched and all cartridges are
control cartridges.
Since 1 cartridge is assigned to 1 path, it cannot be replaced during printing.
3
Ink supply system
The ink filling method of CJV30 uses a suction system with a roller pump, and a pressure
damper with a self-sealing valve.
Ink is supplied with a siphon during printing.
The damper sealing valve opens to supply ink when the discharge pressure drops, and the
sealing valve closes when the damper ink chamber is filled.
The sealing valve reduces the ink path pressure that reaches the head meniscus during the
carriage motion.
4
Replacing ink cartridge
The warning message is displayed if the cartridge is not installed even after a lapse of 10
minutes to prevent the supply system from getting dry.
5
Ink supply valve
For each cartridge, a supply valve is provided to supply ink by opening it.
The supply valve is normally closed and is opened only when ink supply is required.
Ink supply is executed during discharge operation (for printing or flushing) and suction
operation (for cleaning or filling). The supply valve for any cartridge that has developed
an error does not open, thus does not allow ink supply.
6
Ink cartridge LED
For each cartridge, two LEDs (green: control LED; red: error LED) are used to allow the
user to visually check the cartridge state.
Since all 8 cartridges are control cartridges except when 4-color ink set is used, the green
LED is on for cartridges where there is no error.
7
Ink use-up cleaning
(Only for the 4-color ink set)
For cleaning, the printer switches the supply valve to the cartridge that has displayed [INK
NEAR END] or [INK END] to use the cartridge with the smaller amount of residual ink
first. For details, see
