1 Monitoring of cartridge error Monitors a cartridge error when ink is supplied.
For details, see "1.3.2 Ink System Error Monitoring".
2Control and selection of supply
cartridge
Checks the status of the ink cartridge and selects the cartridge (for the 4-color ink set).
For details, see "1.3.3 Supply Cartridge Control and Selection".
3 Updating of cartridge LED status Updates the LED status depending on the status of ink supply and errors.
For details, see "1.3.4 Cartridge LED Control".
4Open/close supply valves Open/close the ink supply valves depending on the control and selection of the ink
supply cartridge.

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.
2When filling other than 4-
Color (“K,Y,W” of 4-
Color +W)
“Y,K,Or,G” of 6-Color
All colors of 6-Color +W
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 During drawing etc., ink is supplied via the ink supply pump.
4Replacing 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.
6Ink 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.
7 Ink supply pump Ink is supplied from the cartridge to the damper.
There is one ink supply pump for one damper.

Monitoring of cartridge error
Monitoring of ink system error
The ink system are checked for any error periodically (every 50 ms), and machine operation is limited according to
the error, if detected. The table below shows the possible errors and the limitations on machine operation.
No. Item Description
1 Cartridge error check A cartridge error is periodically checked (every 50 ms).
 Select the supply cartridge in taking into account the error status and the amount of remaining ink.
2LED control when an
error occurs
The green LED lights up to indicate that the supply cartridge is now being controlled.
The red LED lights up or blinks to indicate that the cartridge must or should be replaced.
3 Supply valve control
when an error occurs
 The valve for the cartridge where the green LED is lit opens when the instruction to open the valve is issued.
When an error occurs in a supply cartridge while the valve is open (during printing or
cleaning), the valve switches to the other cartridge which can supply ink, if any, to continue
machine operation. If a supply cartridge is removed, printing or cleaning will be stopped and
the machine will return to LOCAL mode.

Errors related to the amount of remaining ink
Calculate the number of ink shots by printing and flushing or the amount of ink sucked by cleaning and filling,
and then the amount of consumed ink by subtraction of remaining ink.
When the amount of remaining ink is updated, it is written into the ink IC chip.
A cartridge error is issued according to the amount of remaining ink.
No. Item Description
Error detect timing Limitations after error detection
1 Cartridge near end Detected that the amount of remaining ink in the
cartridge is 10% and less.
2Cartridge ink end This occurs when ink filling cannot be performed
after detecting ink near end.
3 WRONG CARTRIDGE Occurs when the amount of consumed ink exceeds
nearly double the ink cartridge capacity but the ink
end is not displayed yet.
4Damper High Even if a certain amount of ink has been consumed
in the damper, the Hi sensor remains “ON”.
5 Near end Ink supply is impossible, though there is ink. Filling, damper maintenance, air purge
and cleaning cannot be performed.
6Ink end Ink supply is impossible for ink empty in the
damper.
Filling, damper maintenance, air purge,
cleaning and drawing cannot be
performed.
