Description of the invention (3) The crystalline silicon layer is intended only in the field where bubbles are generated For the purpose of heat generation, it is necessary to use the ® domain other than the polycrystalline silicon layer 45 as the heat generating area, that is, the polycrystalline silicon layer 46 as the electrode before reaching the common electrode 41 and the dividing electrode 42 as the resistance of the part of the electrode For this reason, the value of β decreases. For this part of the polycrystalline silicon layer 46, the resistance value can be reduced by implanting ion (phosphorus (P) or arsenic (As)) method. Then, the interlayer green film is formed之 第一 玻璃 层 47。 The first glass layer 47. Here, the first glass layer 47 forms through holes 51 and 52 for connecting the polycrystalline silicon layer 46 whose resistance value has been reduced to the common electrode 41 and the Tsurube electrode 42. After that, a Si3 N4 layer as an insulating layer and a Ta layer 43 as a metal protective layer are formed on the polycrystalline silicon layer 45. Also, the polycrystalline silicon layer 45 as a heating resistor hip is made of aluminum ( A1) A layered plaque patterning the common electrode 41 and the separate electrode 42. At this time, through the through holes 51 and 52 formed in the first glass layer 47, the common electrode 41 and the individual electrode 42 are connected to the polycrystalline silicon layer 46. Then, the second glass layer 48, the insulating layer 28, and the thick film resin layer 29 are formed in this order. FIG. 5 is a diagram illustrating the connection of electrodes and electrodes of a conventional heating resistor. As described above, one end of the heating resistor 27 is commonly connected to the common electrode 41, and the other end is respectively connected to each of the individual electrodes 42. Such a structure is also described in Japanese Unexamined Patent Publication No. 5-338208. If such a connection is represented by a circuit diagram, it is shown in Figure 5. The common electrode 41 is connected to the power supply. In addition, the separate electrodes 42 are connected to each drive circuit, and the current is controlled to flow only to the heating resistance selected by the print signal.

V. Invention description (4) As such, if all the heating resistors 27 are connected to the common fan 41, the heating resistors 27 and the power supply The distance also changes with the position connected to the common electrode 41. In other words, the heating resistor of the common electrode 41 will produce a difference, and the actual voltage applied to the heating resistor 27 will be different, causing a so-called voltage drop problem. If I is the current value and R is the resistance value to the common electrode 4 1 of the heating resistor 2 7, the voltage drop from the power supply voltage vdj: £ jp is,

Vdrop = 1 * R That is, because the central heating resistor away from the power supply has a larger resistance value R than the common electrode of the heating resistor near the power supply, the actual applied voltage is lower. Moreover, the voltage drop vdl :() p also depends on the current value and also changes with the value of the heating resistor 27 to be driven. In this way, when the applied voltage differs according to the position of the heating resistor 27, it will cause the jet standby to change between the nozzles. In addition, for the heating resistor 27 on the side, this central heating resistor It is likely to be a condition of excessive voltage, which causes a problem that the life of the heating resistor 27 is shortened or the change in jet standby becomes large. To avoid this problem, changing the thickness or width of the film of the common electrode or the material can reduce the resistance value. However, if the thickness of the film is increased, unevenness will occur in the insulating layer covering the electrode, and the adhesion to the channel substrate 21 will cause problems. In addition, in order to widen the width, it is necessary to move the heating resistor from the nozzle. However, if the distance from the nozzle to the heating resistor is increased, a loss of ejection energy is involved. In addition, if the resistance value is used, the paper standard is applicable to the Chinese national standard (CNS> A4 specification (210X297mm) (please read the precautions on the back before filling out this page).

Invention description (θ) The image density is not so shallow First, in the case of a color image, the color balance varies depending on the location. Since the maximum voltage difference generated by the position of the heating resistor is 2.GV, in order to control the voltage difference due to the position of the heating resistor to within 0.5 V, if 2 5 6 heating resistors are differentiated according to voltage 4 tilt group is also available. From the 1MA), as the voltage drop shown by the voltage difference with the heating resistor at the end, as the proportion increases from the end to the center, by adding 64 from each of the 32 ends to the same group , Can be divided into 4 groups. Fig. 11 is an explanatory diagram of an example of division of a heating resistor group in an embodiment of the present invention. For example, the group 1 corresponds to the nozzles N # 1 ~ N # 32 and each of the 32 heating resistors with a total M slap, so that the group 4 corresponds to the central nozzle N # 9 7 ~ Ν # 1 6 0 6 4-value heating resistor. In this way, in group 1, it is clear from FIG. 10 (A) that even when the nozzles N # 1 and N # 32 that are farthest from each other due to the voltage drop, the applied voltage difference image is often within 0.5V, The same correction applies. Even in other groups, the voltage difference of each heating resistor in the group is within Q.5V.

In response to the voltage difference, the level 0 ~ 3 is established »This level is also shown in the graph of FIG. 1MA). In addition, the correction level 〇 is a level that does not require voltage drop correction. In addition, the group 傜 is the one correcting the voltage difference from the group 1, so it is usually the correction level 0.

This is summarized in XS1. Figure 1 shows the digital image in the table. Note 1 1 means the voltage correction level of the cuvette. For example, t is in group 3, and the number of simultaneous drives is 1 ~ Item I 5 The common voltage correction level is 0 9 and no correction is needed.

Furthermore, the number of simultaneous drive numbers 11 ~ 16 The maximum electrical difference exceeds 1 1 IV »Knowing that the voltage correction level 2 must be corrected. The 1 I table shown in FIG. 12 can be used as the correction level determination table 7 in FIG. 1 ○ 1 1 Set 1 FIG. 1 3 An illustration of the relationship between the voltage at which ink droplets start to be ejected at a certain temperature and the amount of ink droplets ejected when a predetermined voltage is applied. As mentioned above, the actual applied voltage at which ink droplets are ejected at a certain temperature is referred to as 1 I The injection start voltage of 1 1 is also shown in Q5I as shown in Figure 9 »The injection start voltage changes with the temperature of the printer head 1 1 and the pulse width of the pre-pulse. In Figure 13, I is regarded as Ρ 1 + Ρ 2 + P 3 = 6. 5 as, set the pulse width P 3 of the main pulse to 1 1 as 1 . 4ms, 1.6 // s, 1.8 M s 2.0 μ S The relationship between the amount of ejected ink drops when 37 V is used as the driving voltage is indicated by a solid line. 1 In addition, fix the pulse width P 1 of the pre-pulse with 0> us and 1.0 # s, 1 so that the pulse width P 3 of the main pulse changes from 1.4 to 2.0. | Initiated Μ and 31 V as the driving ink m when the amount of ink droplets ejected 1 In -2 2-1 1 1 1 This paper size is applicable to China National Standards (CNS) Λ4 specifications (210Χ 297 mm) Ministry of Economic Affairs The 3G7718 A7 __B7 _ printed by the Employees ’Consumer Cooperative of the Central Bureau of Standards 5. The description of the invention (Μ) is indicated by a dotted line. In addition, as the optimal control range of the ink drop controller, the range of 19 ± 1.4 pl is hatched. It can be seen from the graph that if the pulse width P1 of the pre-urea pulse is increased, the amount of ejected ink drops increases and the ejection start voltage decreases. In addition, it is also known that the urea stroke width P3 of the longer main pulse, the amount of ejected ink drops is large, and the ejection start voltage is low. As can be seen from this, the ejected ink droplet volume is approximately the same, but there is a driving shock condition where only the ejection start voltage is different. It can be seen from this that the ejection start voltage is mainly dominated by the main pulse width P3, and the ejection ink droplet placement is mainly dominated by the pre-pulse width P1. Therefore, only one of them can be changed by the combination of the two. From the coordinate circle shown in Fig. 10 (A) and the table shown in Fig. 9, it is determined only by the position (group) of the heating resistor and the number of simultaneous driving (1.5 V scale applied voltage difference, if the injection is reduced, The voltage may not depend on the type of pattern (the number of simultaneous drives) and the position of the thermal resistance, but the difference between the actually applied voltage and the voltage necessary for ejection is almost constant (within 0.5V) between the heating resistors. As mentioned above, ink droplets are ejected The quantity is also greatly affected by the temperature W. In this embodiment, the temperature of the inkjet printer head is measured based on the thermistor installed in the inkjet printer head, and the measured temperature of the printer head is also used The signal changes the driving urea flushing condition, which can control the amount of ink droplets ejected without depending on the temperature.
