In the case where the vapour pressure of ethyl alcohol is located at the region on the right side of vapor pressure curve, ethyl alcohol is gas；In ethyl alcohol
In the case that vapour pressure is located at the region in the left side of vapor pressure curve, ethyl alcohol is liquid.Thus, for example printer setup is in room temperature
In the case where 25 DEG C of room, if the vapour pressure of ethyl alcohol is more than about 8kPa, become liquid.
In the usually used environment of printer, steamed relative to saturation can not be risen in the open print cartridge 2 of outside air
Air pressure, therefore, the solvent in print cartridge are evaporated and are discharged into outside air.Therefore, it is recycled by groove 51 and returns to print cartridge 2
The solvent of ink is evaporated as time goes by and is discharged into the atmosphere, and causes the viscosity of ink to increase, so needing recharge solvent.
In contrast, in the case where using solvent evaporation dampening mechanism 10 that print cartridge 2 is closed, if recycled by groove 51
Ink returned into box, then vapour pressure rise and reach saturated vapour pressure about 8kPa.If following ink is returned into box
And the air pressure in box is made to be more than saturated vapour pressure, then the quantity of the molecule of the solvent condensed is more than the quantity of the molecule of evaporation,
So the evaporation of ink solvent is inhibited.

Fig. 5 (b) show make in the chart of Fig. 5 (a) print cartridge in an atmosphere open wide when solvent-oil ratio 0 when, with
50kPa pressurize to print cartridge in the state of solvent-oil ratio reduced rate.
From the chart of Fig. 5 (b): print cartridge is closed and remain ink solvent saturated vapour pressure more than situation
Under, compared with by print cartridge in an atmosphere open situation, solvent-oil ratio can be made to reduce to 50% to 80% or so.
In addition, the composition of the ink for using methyl ethyl ketone as solvent, in methyl ethyl ketone (70~90%)
The chromium complex salt (5~10%) as black dyes is added, and is wherein adding several hexamethylene (5~10%) and isopropanol
(0.1~1%).
On the other hand, for using the composition of the ink of ethyl alcohol as solvent, conduct is added in ethyl alcohol (70~80%)
The chromium complex salt (5~15%) of black dyes, and wherein adding several isopropanol (lower than 5%) and normal propyl alcohol (5~15%).
The explanation for returning to Fig. 1 in present embodiment, is equipped with branch pipe 5j in a manner of around check-valves 58 on pipe 5i,
Open and close valve 66 is configured on branch pipe 5j.Pressure of the controller 9 in the pipe 5i measured by pressure sensor 74 has been more than regulation
Value when open and close valve 66 is opened.When check-valves 58 breaks down for some reason and can not open, open and close valve 66 is opened,
Thereby, it is possible to reduce the air pressure in print cartridge 2, to prevent box from deforming or being crushed.
Open and close valve 66 is also used in maintenance test printer 1, the lid 22 of print cartridge 2 is opened and to being cleaned in box
When, by reducing the air pressure in box, ink ejection etc. can be prevented.
