[0009] At present, the ink cartridge or continuous ink supply system needs to be installed on the inkjet printer of the corresponding type to test the ink cartridge or the continuous ink supply system, which causes the inkjet printer used for the test to work at a high intensity for a long time and is easily damaged, and the manufacturer of the ink supply container needs to purchase a large amount of inkjet printer ink printers for testing work, resulting in higher testing costs for ink cartridges or continuous ink supply systems, which in turn drives up production costs for ink cartridges or continuous ink supply systems

Embodiment Construction
[0028] The invention provides a test system for testing the printing fluency of the ink cartridge or the continuous ink supply system by simulating the working environment of the ink cartridge or the continuous ink supply system when the inkjet printer is working. Since each printing operation of an inkjet printer includes multiple operations such as machine cleaning, printing and process cleaning, and the print head of the inkjet printer produces ink absorption to the ink cartridge or continuous ink supply system during machine cleaning, normal printing and process cleaning Negative pressure has different pressure values, so this embodiment sets multiple pressure regulating valves to simulate the negative pressure conditions under different states such as machine cleaning, normal printing and process cleaning, so as to facilitate testing of ink cartridges or continuous ink supply systems.
[0029] see image 3 In this embodiment, the vacuum machine 10 is used as a negative pr...

The invention provides a system and method for testing an ink supplying container. The system comprises a negative pressure source; the negative pressure source is connected with a pressure stabilizing valve; the pressure stabilizing valve is connected to a first pressure regulating valve and a second pressure regulating valve through an air duct; the first pressure regulating valve and the second pressure regulating valve are respectively connected to a first ink cylinder and a second ink cylinder; a suction tube is communicated with the first ink cylinder and the second ink cylinder; and the first end of an ink guide tube extends into the first ink cylinder, and the second end of the ink guide tube extends out of the first ink cylinder. The method comprises the following steps of: connecting the second end of the ink guide tube to an ink outlet of the ink supplying container to be tested; starting the first pressure regulating valve and the second pressure regulating valve; detecting whether bubbles exist in the ink guide tube or not by an ink shortage alarming device; transferring detected ink level data to a controller by a liquid level sensor; and judging whether the ink level in the first ink cylinder declines or not by the controller according to the received data. The system and method provided by the invention can be used for simulating an ink jet printer to test the ink supplying containers, so that the testing cost and the production cost of the ink supplying containers are reduced.
Description
technical field [0001] The invention relates to the printing field, in particular to an ink supply container testing system for testing an ink supply container containing ink and a testing method for the testing system. Background technique [0002] The desktop inkjet printer mainly uses the ink cartridge which is detachably installed in the carriage to provide the ink sprayed to the paper to form the required characters and patterns on the paper. [0003] A desktop inkjet printer such as figure 1 As shown, the inkjet printer 1 has a trolley 2, and the trolley 2 has an accommodating portion 3 for accommodating one or more ink cartridges 5 detachably installed in the trolley 2, each ink cartridge 5 is filled with inks of different colors, for To supply ink to the inkjet printer 1 and form patterns on paper. The lower end of ink cartridge 5 is provided with ink outlet ( figure 1 not visible), the ink contained in the ink cartridge 5 supplies ink to the inkjet printer 1 thro...
