2-1-6. Ink System
Ink Supply Control
Ink filling method of JV33 is a suction system with roller pump, a pressure damper with a self sealing
valve is used. Ink supply at drawing is a siphon supply. The sealing valve is opened by discharging
pressure reduction to supply ink, and when the damper ink chamber is filled, the sealing valve is
closed. The ink path pressure at carriage moving conveyed to the meniscus of head is eased by the
sealing valve.
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 (4-color only). Since there is
1 path per cartridge for except for 4-color, replacement during use is not possible.
During the ink end cartridge replacement, in order to avoid dehydration of ink supply system, a
WARNING is displayed if a cartridge is not placed for more than 10 minutes.
A supply valve is placed for each cartridge to supply ink at the supply valve OPEN. The supply valve
is usually in CLOSE state, and when ink supply is necessary, the supply valve turns to OPEN state.
Ink supply is conducted at discharging operation (drawing and flashing) and suction operation (clean-
ing and filling). The supply valve is not opened for a cartridge having an error not to supply ink.
2 types of LED (Green: control LED / Red: Error LED) are placed for each cartridge to allow a user to
check a state of cartridge in visual. Since all 8 cartridges for except for 4-color are control cartridges,
the green LED is on for cartridges where there is no error.
JV33 switches the supply valve at occurrence of “INK NEAR END” or “INK END” in the cleaning to
use a cartridge having smaller residual quantity. As for details, see Ink wear-up cleaning (4-color
only) (P. 2 - 1 6 )
. (4-color only)
Device configuration
The device configuration of ink supply path is shown below.
The firmware switches select whether the inkset configured at the initial filling is 4-color or not.
