Embodiment 1

[0043] A method for detecting the remaining amount of ink, which is used for detecting the presence or absence of ink, comprises the following steps:

[0044] 1. Set a predetermined value greater than the normal suction power;

[0045] 2. Detecting the amount of ink The detection part detects whether there is ink in the position, if there is, it will print normally, if there is no ink, then enter step 3;

[0046] 3. Compare the real-time suction power with the predetermined value, if the real-time suction power is less than the predetermined value, go to step 4, otherwise, go to step 5;

[0047] 4. Increase the suction power and go to step 2;

[0048] 5. Reminder that the ink is exhausted.

[0049] In step 2, it may further comprise that the ink quantity detecting component transmits the first electrical signal indicating that there is no ink at the position to the controller.

[0050] In step 2, it may also include that the ink quantity detection component transmits the fi...

Embodiment 2

[0055] image 3 Embodiment 2 is a schematic diagram of an ink supply system in a printer utilizing the method of Embodiment 1. Inkjet printers, including: ink supply systems, printing equipment. The ink supply system in an inkjet printer is like image 3 The ink supply system shown includes: an ink remaining detection mechanism, a secondary ink chamber 2 , an ink channel 23 , a print head 3 , and a terminal device 10 . Ink is sprayed from the ink supply system onto the medium P (generally paper) according to the printing task. The remaining ink amount detection mechanism is used to detect whether the ink amount is in an ink-end state. The remaining ink amount detection mechanism includes: an ink cartridge 4 , an ink suction needle 9 , an ink flow path 8 , an ink amount detection component 5 , a suction power control unit 6 , and a controller 7 . The suction power control part is provided with a predetermined value larger than the normal suction power; during the printing p...

Embodiment 3

[0059] Figure 5 It is a schematic diagram of the ink supply system in the printer of the third embodiment. like Figure 5 As shown, the ink cartridge is provided with a chip 41 . Ink quantity information is stored in the chip 41 . like Figure 6 As shown, when the first electrical signal is generated, step S401 will be executed to transmit the first electrical signal to the chip 41 , and after the chip 41 receives the first electrical signal, step S402 will be executed to correct the ink volume information in the chip 41 .

[0060] The first electrical signal generated by the ink volume detection component 5 can correct the ink volume information stored in the chip 41 and improve the accuracy of the stored information in the chip 41 .

Abstract

The present invention relates to a method for detection of ink residual, an ink residual detection mechanism, an ink supply system and an ink jet printer. The method is configured to detection whether there is ink or not. The method comprises the following steps: 1, setting a presetting value having larger suction power than the normal suction power; 2, detecting whether the position has ink or not through an ink residual detection part, and if the position has no ink, entering the step 3; 3, comparing the real-time suction power to the presetting value, if the real-time suction power is smaller than the presetting value, performing the step 4, and on the contrary, turning the step 5; 4, adding the suction power, and entering the step 2; and 5, prompting that the ink is exhausted. After the ink residual detection part detects that the position has no ink, and the suction power of an ink suction needle is increased to allow the ink remained in an ink box to be pumped out until the power to be sucked reaches the presetting value and the ink residual detection part detects that the position has no ink, the printer prompts that the ink is exhausted. The method for detection of ink residual, the ink residual detection mechanism, the ink supply system and the ink jet printer can accurately detect the ink residual in the ink box to allow the ink residual in the ink box to reach the minimum and avoid the damaging caused by the air suction of the ink suction needle.

Description

technical field [0001] The invention mainly relates to the technical field of ink remaining detection technology, in particular to a method for detecting ink remaining, an ink remaining detection mechanism, an ink supply system and an inkjet printer. Background technique [0002] Inkjet printers use ink cartridges to store ink, which is supplied to the printheads according to printing needs. Whether the amount of ink inside the ink cartridge can be accurately detected is related to whether the ink is used up, and it is an important detection in inkjet printers. At present, there is a chip on the ink cartridge, and some ink cartridges rely on the chip to indicate the amount of ink. The chip will estimate the amount of ink. When the ink is used up, the chip will transmit a message that the ink is exhausted to the printer, so that the printer will indicate that the ink is exhausted. [0003] Because the above method does not detect the amount of ink, only rely on the chip info...
