Description
Technical field:
The present invention relates to printer apparatus, particularly relate to the ink feeding system of a kind of ink-jet printer.
Background technology:
Ink-jet printer uses technology mainly to have two kinds: continuous ink jet technology and random mode ink-jet technology.The ink-jet printer of ink-jet printer in early days and current large format is all the continuous ink jet technology that uses, and the most commonly used random ink-jet technology of ink-jet printer that current market is popular.The only just injection when printing needs of random mode ink-jet system ink inside, so being also called on-demand.It is compared with continuous way, simple in construction, low cost, and reliability is the highest, enjoys the favor of consumers in general.
The ink-jet system of circulation continuously. high speed ink droplet can be generated, so print speed is high, it is possible to use common paper.Different print media all can obtain high-quality print result, is also easy to realize colour print.But, the structure of this ink-jet printer is compared with random mode, more complicated: ink needs pressue device, and terminal retracting device to be had reclaims and is not involved in record, and the efficiency of working method is not high enough, and inaccuracy.
Existing random mode ink-jet printer in the future, need to will frequently change print cartridge when using one section because of ink, and this measure not only causes the trouble that user uses, and more improves printing cost because of the costliness of print cartridge expense.It is the most out of ink or print uneven phenomenon that traditional ink-jet printer there will be spray in ink jet process, find that ink gun enters air after investigation reason, air bag is formed so failing to print ink at nozzle, therefore ink-jet printer air-discharging is also important link, and reality enters to be intended in the problem of air take out the print cartridge in printer at process ink gun more, ink gun is cleaned draw back the ink in ink gun with needle tubing after, this measure is too complex in operation, also need to the air-out that user is artificial, and effect is undesirable.
Summary of the invention:
The invention aims to solve the deficiencies in the prior art, propose a kind of easy and simple to handle and ink gun ink feed speed fast and the ink feeding system of the uniform printer of ink gun ink-jet, its technical scheme is as follows:
A kind of ink feeding system of ink-jet printer, it is characterised in that: including:
