2. After four year long research including many iterative practices ,the technique was proved to be viable and reliable .By using this method ,the life time of the printer nozzle won't be decreased , contrarily it can be highly extend the life time and protect it from blocking ,since it avoids two conditions which lead shorter life time of nozzles ,such as condition when the
cartridge needs to be replaced ,a nozzle is forced to refill and condition when a cartridge is out of ink so that the nozzle becomes too dry.
3.Most directly and most completely decreased the cost if users ,which enables lookout of the development of the this technique market to become huge .Using continuous ink supply system tens of times of the cost can be saved ,why not choose this system ! So we decided price for a single printer adaptation as €100 per printer ,this price is even higher than the printer itself ,but still there are more and more clients coming to ask us to adapt their ones.
4.The production of the components of the ink supply system have become batch of open-mould production ,the components suit the above brands of four-color ,six-color and A3-breath ,and A4-breath printers .For printers with chips ,a decoder which can resume quantum of the cartridge and a software which can be used to modify records of the ink level in the cartridge by using the computer software .It's applicable to the current nearly all EPSON / CANON / HP printers.
5.After four year practice ,experimentation and filtering ,we have abundant experiences of using the continuous ink supply system ,it is guaranteed that ink in the printer after adapted can become smoother.
