System.
Background technique
The ink system of ceramic ink jet printer directly determines print quality.The pressure for being supplied to the ink of spray head is stablized
Property and temperature are most important to ink-jet printer continuous work.
The shortcomings that existing ink supply mode, has：
(1) ink supply lags in response, ink supply amount are difficult to be adjusted to the demand for adapting to unit printing.Since liquid level sensor exports
Signal is switching value, therefore can only set a certain fixed speed when ink supply, controls opening for ink-suuplying pump according to the signal of liquid level sensor
Stop coming ink supply, therefore ink supply can only alleviate the big wave that ink-suuplying pump frequent start-stop generates print cartridge liquid level with delay process when controlling
It is dynamic.But handle in this way, while will cause ink supply lags in response, it is difficult to adapt to the ink amount that printer consumes in real time and be mended in time
It fills.
(2) negative pressure is had an impact larger.The fluctuation that print cartridge liquid level generates is larger, therefore fluctuates caused by the negative pressure of print cartridge
Also larger, to influence printing effect.
(3) it is easy to hang ink using proximity liquid level sensor, generates malfunction, influence normal ink supply and even print production.
It when maintenance test channel, needs to pull channel, at this moment the liquid level on print cartridge can generate great fluctuation process, and ink did not had liquid level sensor
Afterwards, liquid level sensor bottom just hangs with ink droplet, so that the normal error signal of print cartridge liquid level is generated, when unit starts printing consumption
After ink, control system can not ink supply, it is final to influence printing production.
