Description of the invention (1) Background of the invention. Cases related to the invention. This invention is a co-examination case filed on April 30, 1998. Serial number 09 / 070,898. Part of the F (invention name: inkjet ink level detection) is a continuation of the case. The invention is directed to the inkjet printing system, which has an ink water level detection system, which uses the optical characteristics of the capillary ink-containing substance to change the water level detection method. "The inkjet printer is based on the print head Ink droplets of ink are sprayed onto the printed medium. The print head is mounted on the inkjet pen, which is placed in an appropriate position for the medium. The ink must be sent to the print head under appropriate post pressure '(That is lower than the surrounding atmospheric force)' It prevents ink from dripping from the inkjet head when the inkjet pen is not operating. Various mechanisms have been used to hold the ink under the proper back pressure, which include: an elastic buoy, a multi-cell foam 'internal accumulator' bubble generator, and an elastic bag with a spring. When the pen's ink is depleted 'it may be advantageous or it must automatically sense the pen's empty state immediately. For example, this system may be designed to auto-fill the pen 'with a flexible tracking tube or an automatic filling station. In addition, if the pen is empty, the inkjet head may be damaged. Various mechanisms have been developed to sense the ink level of inkjet pens. US Patent No. 5,751,300 (Cowger et al.)

This printing system includes a printer 10, which has a chassis 12, a magazine bar 4, a magazine 16 'a compartment 18, an ink library 20, 22, 24, 26' pen 28, 30 ' 32 '34 C (shown in dotted lines) and controller 36 Connected to the chassis 12 is a loading tray 38 and an output tray 40 »The controller 36 is communicatively connected to a main printing device (not shown). The personal electronic print system receives the image and / or text data signals to be printed. The controller 36 is also connected to the pens 28, 30, 32, and 34, and is connected to a medium advance motor and a car advance motor (not shown). The trolley 16 is mounted on the rod 14 and back and forth on the medium to be printed. When scanning. At the appropriate time, the controller 36 causes the car advance motor to control the car 16 to draw X in advance of the car and draw the pens 28, 30, 32, 34 on a small piece of paper 50 present on the medium to be printed. When the pens 28, 30, 32, and 34 are selected on the printed medium, the 'print head' will be ejected by the controller 36 with a small drop of ink on the paper in the expected dot matrix mode. When the scan is over, the controller 36 sends a signal to the media advance motor to advance on the paper progressively.

Multiple proximity The horizontal round is printed in this way to complete the desired image on the paper. The β ink is supplied by the ink bank 20, 22, 24, 26 through a tube 45 connected to a pen 28 '30' 32 '34. When When the ink of any ink bank is dead, it will be replaced by a new ink bank. At some time, one of the pens 28, 30, 32, and 34 may not be illuminated. In this case, the The pen can be replaced by the user or a trained technician. Section 2 illustrates that the pen 28 includes an external device 50, a print head 52 'a mesh filter 54, an inner wall 56, and glass beads 58. The outer wall 50 of the device is Made of transparent high-density polyethylene or polypropylene As shown in the 6th step, the inner pen defines a small second slot 66. The pen 58 has an input port 68 to receive ink and an air outlet 70. The body of the pen is filled with glass beads 58 such as (Figure 68. Port 68 is fluidly connected to tube C (see Figure 1), which is connected to the ink cartridge 20.) An adapter 54 is placed in front of the print head 52 to prevent glass beads from falling to the small secondary chamber 70. The filter 54 also prevents other substances and air from reaching the print head. The air passing through the beads 58 is blocked by the filter 54. The filter 54 is expected to be composed of a stainless steel wire mesh and its holes are about 20 micro centimeters. Ink approaching the filter net will surround the penetrating glass beads. Beads that are wet but only partially penetrated will extend out of this space. Some of the filled beads have an interface between ink and air, which generates a negative voltage. When the ink is ejected from the print head, the interface between the partially penetrated beads and the fully penetrated beads moves toward the filter net. When the damper 54 is wet, the damper will generate a large bubble bed pressure * 8- This paper size applies to the Chinese National Standard (CNS) M specification (210X297). ---------- ------ ΐτ ------ ^, (please read the notes on the back before making this page)} The consumer cooperation of the Central Bureau of Standards of the Ministry of Economy Du Yin 12. 445214.

The average diameter of the broken glass beads 58 is about 0.012 inches, and its diameter is Fanyuan Approximately from 0.010 inches to 0 016 inches. Existing typical nozzle inks of about 1.5 inches of water will cause back pressure on the beads. The size of the beads can be adjusted to meet the pressure requirements behind the print head. Discussed below The ink flowing from the tube into the pen 28 is caused by the pressure of a pumping mechanism (not shown). The β ink flows into the pen 28 to a small chamber 60. In this chamber, the ink will be absorbed by the beads 58. It has been found that the ink flows to The bottom of the pen and the flow to the top of the bead 58 do not put more pressure on the print head 52. Section 3 explains that the pens 28, 30, 32, 34 are connected to £ 16 The ink level sensor 60 is used to measure the position change of the glass beads 58 in each pen. The ink level sensor 60 includes two blue (481nm) light emitting diode vacuum tubes 62 from Hewlett-Packard Company. An optical detector 64. The optical detector 64 is a Texas Instruments TLS250, which includes an optical bipolar vacuum tube and a super-impedance amplifier. The optical detector 64 is electronically connected to the controller 36. Cassette 16 scans each A pen 28, 30, 32, 34 can reach the pen through the light emitting diode vacuum tube, and the optical detector 62 can detect the change of the glass beads. The optical detector 64 and the light emitting diode vacuum tube 62 Both are fixed on the printer 10 near the right-hand side on the 1st circle, but ca n’t be seen on the 1st》 An important feature of choosing glass beads is that they can be adjusted according to the ___- 9 · I paper size in the beads.

When the glass beads are not penetrated by the ink, their appearance is white and looks like white snow. When they are penetrated by the ink, they take on a different water color. When the beads are no longer soaked, it appears. It is a very light ink color, that is, a very real reflection. For the naked eye, it can easily detect changes. The following discussion can refer to Figure 6-9. The test results show that for each ink color, blue Color, magenta, yellow, and black, the glass beads reflect a detectable change that occurs within them, from their permeation state to non-permeation state β, so this change reflects that it can be detected by an optical ballast. Another important characteristic of glass beads is that they maintain the ink at a proper back pressure. The capillary principle has the ability to provide a pressure margin due to the interaction of three physical components, one for liquid thinking, one for solid thinking, and one for gas ships. For existing purposes, the liquid is inkjet ink, the solid is capillary material, and the gas is air. Capillary pressure depends on the surface tension of the liquid, the coagulation force between each liquid atom, and the adhesion between the liquid atoms and the solid element. An important method to measure the capillary principle of the atomic interaction between a liquid and a solid is the contact angle when the liquid is placed on the solid. High-density polyethylene wall material and ink have a higher contact angle compared to glass beads. This means that polyethylene is less likely to get wet with ink compared to glass beads. This fact is very important. For the function of the non-stick ink sensor, an easily wetted window may have a film of ink remaining, which may cover the reaction of the glass beads (that is, the penetration of the ink). When selecting a capillary substance for a pen, you must consider that it is not only static but not -10. This paper size applies the Chinese National Standard (CNS) Α4 grid (210 X 297 mm).

Description of the invention (8) The same main points of the capillary, and the dynamic resistance to the ink flow must be considered. Refilling the pen quickly with ink is very important if the refill job is printed on the sheet. Generally speaking, I would expect a substance that can be easily penetrated to reduce convection. Zhao Shi is a substance that is easy to wet. It has a low contact angle. There are two methods to reduce the resistance of the ink flow.

Description of the invention (9) inch and lower permeability, its ratio More permeable substances can easily achieve the same capillary pressure. Small pore size and low permeability may cause unacceptable pressure loss and abnormal ink flow at high ink flow rates. The second method is to have a very wet material that may reduce the resistance to ink flow. The resistance is caused by reducing the threshold pressure so that the penetrating substance starts in the ink. It has been noticed that ink in penetrating substances will have a hysteresis that resists movement to the air or liquid interface until it reaches a threshold pressure. This phenomenon can be observed by the raindrops sticking to the windshield, and the strength of this resistance increases with the increase of the contact angle. In other words, the resistance to movement of a given liquid (such as ink) will be higher than a permeable substance that is less permeable. Glass beads are a good penetrating substance for inks. "Glass has a small contact angle with liquids such as water, alcohol, carbon tetragas, xylene, glycerol 'acetic acid. Liquids can advance at low contact angles with a clean and smooth surface of glass beads. The fourth aspect is the display performance of the present invention in a printing system, which includes a pen 28, an optical sensor 60, a pressure ink tank 20, a shutter 80, and a tube 46. A personal computer 82 is connected to the controller 36 ^ When the optical sensor 60 detects a low ink level, a signal is sent to the controller 36 »According to this signal, the controller will open the shutter 80 to allow pressurized ink to flow into the pen 28 . The controller 36 opens the shutter 80 to allow the pen 28 selected in advance to be filled with ink-this amount is selected to be sufficient to bring the pen from a low load to a full load. When the low ink level is detected, the amount of ink per refill is approximately the same 'because the low water level is detected at approximately the same position. The printing system can therefore __ · Π_ This paper size is applicable to China National Standard (CNS) Α4 specification (210x297 public director) ---- see -------- V ------ it (please read ^ Note on the reverse page again) Printed by the Central Bureau of Procurement, Ministry of Economic Affairs and Consumer Cooperatives 445214.

When the low water level is detected, the controller 36 will open the valve again to refill the pen 28. This process is repeated until the ink library is empty, and when the ink library 20 is empty, it is discarded and replaced with a new one. Fig. 5 is a physical diagram of intermittent filling or segmented implementation of the present invention in a printing system. Only one pen and ink library are mentioned but refer to Figure 1-4 to understand that this discussion represents multiple pens. This printing system includes a pen 90, an optical sensor 92, a controller 94, a carrying motor 96, a shutter 98, and an ink library 100. The controller 94 is also connected to the personal computer 102. The ink-jet pen 90 has a transparent wall and is provided with glass beads. The optical sensor 92 optically detects the ink level of the pen based on the reaction of the glass beads. When a low ink level is detected, the controller 94 sends a signal to the carrying motor 96 to indicate the flow contact position of the pen 90 in the ink bank 100. When the pen 90 is in this position, the controller 94 will activate the shutter 98 to Water in the ink bank 100 was filled into the pen 90. Figures 6 to 9 illustrate the relationship between the readings of the ink sensor and the ink depletion, which are blue, magenta, yellow, and black ink, respectively. The ink removal is measured in millimeters and the sensor is measured in millivolts. These figures show that an absolute change in the sensor volts will cause the ink to leave the pen. When the ink reservoir is full, the beads are completely penetrated by the ink, and the sensor volts for all colors are about 350 to 400 mm. This low volt level represents the first reaction of glass beads. "When the ink is depleted from the pen, the permeation of the beads is reduced." Their response increases and at the same time the volt level of the sensor increases. In the case of lack of ink, the controller can program to select a specific volt. 13- This paper size applies the Chinese National Standard (CNS) A4 specification (210 × 297 mm). 乂 Please read the precautions on the back first. ≫ This page)-Binding and binding line 4452 1 4 Α7 Β7 V. Description of invention (11). For example, '1000 millivolts may be selected for all colors as the condition without ink. Another alternative is that each color has its own unique edge level. For example, the output voltage level of 6 圊 -9, blue may choose 1000 millivolts as its level, and other colors may be 500 millivolts.
