No. Item Description
1 When filling 4-color ink
set
M and Bl ink when filling
6-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.
2 Except M and Bl ink
when filling6-color ink
set
When filing 8-color or 6-
color+W  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 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, LED is used to allow the user to visually check the cartridge state.
Green color lights in control. Red color lights in error.
 Since all 8 cartridges are control cartridges except when 4-color ink set is used or except M
and Bl ink when 6-color ink set is used, Green color lights on for cartridges where there is no
error.
7 Ink use-up cleaning
(Only for the 4-color ink
set)  For cleaning, the machine 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
"1.3.7 Use-up Cleaning" .
