The scanning mechanism includes a slide bar 26 that allows the scanning stage 20 to slide on the scanning stage when it moves through a scanning axis. A positioning tool (not shown) is used to accurately position the scanning platform 20. Furthermore, when the scanning stage 20 moves through the scanning axis, a paper feeding mechanism (not shown) is used to feed the printing medium 22 into the printing area. Telecommunications are provided to the scanning station 20 to selectively trigger the print head 16 by an electrical link, such as a ribbon cable 28. The inkjet printing system 10 shown in Fig. 1 is configured to receive an ink valleyr 12, which has an ink extraction characteristic which varies depending on the ink level in the ink container. The ink extraction characteristics generally vary depending on the size of the ink container 12. An example of the ink extraction characteristic is the reaction force characteristic in the ink container 12. When ink is drawn from the ink container 12, the reaction force in the ink container 12 is different. This difference in reactivity, if not given to the printing system properly, can lead to many problems with the printing system. These problems include a decrease in print quality due to continuous reaction, a reduction in the reliability of the print head due to the intake of air, and an increase in ink stranding in the ink container 12, and the like.

For example, if the value of false δ is different due to the ink level in the ink container 12, for a specified extraction rate, the counter stress will increase as the ink is extracted from the ink container 彳 2. Therefore, if this extraction characteristic is not properly given, the printing system 10 cannot extract ink at a low ink level, and when the ink level is low, the reaction force is the highest, causing the ink in the ink container 12 to be twisted. The stranding of ink in the delta ink trough unit 12 results in waste of ink, the cost of printing on the southern mother page, and the stranded ink entering the waste stream. An electric storage device is connected to each of the replaceable ink containers 12. The electric storage device contains ink extraction information related to the special replaceable ink container 12. The installation of the replaceable ink container 12 to the printer section 10 enables the ink extraction information to be transmitted between the electric storage device and the printer section 18 to ensure high printing quality and complete improvements since the replaceable Extraction of ink from the ink container 12. The information provided to the printing system 10 includes, among other things, the ink extraction rates specifying the different ink volumes in the ink container 12.

Description of the invention ( 19) "Commonly known as" print drive ". To ensure that the printing system 10 provides high-quality images, the operation of the controller 29 must be supplied to a special replaceable ink container 12 installed in the printing system 10. The electric storage device 80 is connected to each replaceable ink container 12, which provides special parameters to the replaceable ink container 12, to allow the controller 29 to make These parameters are used to ensure the reliable operation of the printing system 10 and to ensure high-quality printed images. Figure 10 shows the comparison of the reaction force in the ink container 12 with the ink extracted from the ink container 12. Figure 10 The reaction force or standard pressure shown is a negative pressure because this pressure is lower than atmospheric pressure. In short, the reaction force in the ink container exhibits an amount or a negative direction as the standard pressure. In the figure, the reaction force is stated in mercury column inches, and the extracted ink is stated in cubic centimeters of ink. Generally, when the ink is extracted from the ink container 12, the reaction force or standard pressure tendency in the ink container For increasing or becoming more negative. As shown in Figure 10, the reaction force has two component forces, the static reaction force is represented by curve 98, and the dynamic reaction force is represented by curve 100. As the reaction force in the ink container 12 increases, the amount of drops ejected from the print head 16 tends to decrease. Once the reaction force reaches the limit operation reaction force as indicated by the curve 102, further increase of the reaction force will reduce the printing quality. The print quality is reduced due to the drop volume difference. If the drop volume difference is sufficient, the output image can be degraded or the color tone of the printed image can be changed. In addition to the loss of printing quality, it can also produce 22 paper sizes applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) 丨 Installation-Order —; Line 丨 584600 V. Description of the invention (20) Damage to or damage to the print head 16, if it should be severed, "6" If it is operated for a long time under high response. The damage of the print head 16 is caused by the intake of air or thermal damage caused by the reduced ink flow through the print head 16. The technology of the present invention allows the reaction force in the ink container to be maintained below the limit operation reaction force to prevent degradation of print quality, prevent damage to the print head 16, and enable ink to be more fully extracted from the ink container. 12. In discussing the details of the present invention, such as 'the discussion of the static and dynamic reaction force components will be helpful', each of the component forces is one of the reasons for reducing the printing quality. The static reaction force is a reaction force or 'quasi-pressure' in the ink container 12, which exists when ink is not drawn from the ink container 12. When the printing system 10 is not printing, a static reaction force or a static reaction force exists in the ink container 12. The component of this static stress is caused by one of the capillaries in the ink container 12: the capillary of the storage element. The capillary storage element is a fiber network in a preferred embodiment, which forms a self-contained structure. The fiber networks define the spaces or gaps between the fibers, and the fibers form a tortuous crack path. This crack path formation = has excellent capillary characteristics, so that the ink remains in the capillary official storage: In the illustrated embodiment, when the ink is extracted from the zigzag crack path in the tube storage element, the static reaction The μ-force increased from one inch to about six inches of mercury. In the examples and embodiments, the capillary storage element is a pair of ............ ¥ —— (Please read the precautions on the back before filling This page),? Τ—: Line 丨 23 584600 A7 B7 V. Description of the invention (21) (Please read the notes on the back before filling this page) Component fiber, which has a polypropylene core material and a polyethylene pair A sheath material. This bicomponent fiber is described in more detail in the U.S. patent application titled "An Ink Storage Tank for an Inkjet Printer", Agent Case No. 10991407, with David Olsen, Jeffrey Pew and David C. Johnson filed their claims on October 29, 1999 and transferred to the assignee of the present invention. The dynamic component of the reaction force indicated by the curve 100 is the reaction force in the ink container 12, which is caused by the ink drawn from the ink container 12. It can be seen from the curve 100 that the ink extraction rate constant of 13 cm / minute from the ink container 12 is constant, and the reaction force increases as the amount of ink extracted from the ink container 12 increases. As represented by curve 98, the component force of the dynamic reaction force tends to be higher than the component force of the static reaction force. The component of the dynamic reaction force is the resistance against the action of the zigzag capillary ink path of the ink drawn from the capillary storage element. As more ink is drawn from the capillary storage element, the capillary path that ink must flow through to be drawn from the storage element tends to increase. The increase of this extraction path tends to increase the reaction force in the ink container 12. The ink comes out of the ink container 12 at a continuous extraction rate of 1 cm3 / minute. When about 27 cm3 is drawn from the ink container 12, the dynamic reaction force indicated by the curve 100 reaches the limit operating counter-stress 102. In addition, when the ink container 12 draws ink at an extraction rate of 1 cm3 / minute, the reaction force beyond the limit operation will cause printing 24. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). (twenty two)

Damage to brush quality. The technology of the present invention allows the extraction characteristics to be used to adjust the ink extraction rate to prevent the printing system 10 from operating under a reaction force that exceeds the limit operation. In the illustrated embodiment, the extraction rate is reduced from 1 cm3 / minute to 0.25 cm3 / minute to allow ink to be extracted from the ink container 12 more. At an extraction rate of 0.25 cm3 / min, the limit operation response force represented by the curve 102 was not reached until approximately 35 cm3 was extracted from the ink container 12. By adjusting the ink extraction rate from the ink container 12 such as the difference between the ink extracted at a 0.25 cm3 / minute extraction rate and the ink extracted at a 1 cm3 / minute extraction rate, an additional 8 cm3 can be extracted from the ink container 12 Ink. The ink extraction rate from the ink container 12 is directly related to the print rate of the print head 16 being violated. Many techniques can be used to reduce the print rate of the print head 16, thereby reducing the extraction rate from the ink container 12. These techniques include selecting a printing mode from a number of different printing modes. Each printing mode is configured to have a different ink extraction rate. As such, the printing mode or extraction rate is selected based on the ink extraction characteristics of the ink container 12. For example, when a printing mode is printing, each printing frame has a selected interruption time. This interruption in printing tends to reduce the average value of the ink extraction rate from the ink container 12 in the printing towel field. Other printing modes can be added, each with a different selection time during which printing is interrupted. Optionally, the print mode can only drive 25 A7 on the print head

This paper size is in accordance with China National Standard (CNS) A4 (210X297 mm). A look-up table is stored in the electric storage device 80 on the ink container 12. This look-up table contains a series of extraction rate values, which are relative to the amount of conversion of ink extracted from the ink valley device 12. Among the stated ink extraction amounts, an extraction rate indicates that to increase the ink amount, it can be extracted from the ink container 12. As represented by step 108, the ink container is first inserted into the printing system 10. After insertion, the controller 29 reads the extraction characteristic biometric table, which is stored in an electric storage device 80 connected to the ink container 彳 2. As indicated by step 112, the controller 29 then determines the amount of ink remaining in the ink container 12. The amount of ink remaining in the ink container 12 is stored in an electric storage device 80 connected to the ink trough device 12, that is, optionally, the controller 29 records the amount of ink printed to determine the ink container 12 The amount of ink remaining in. Assuming that the controller records the amount of ink printed, this information can be stored in the electric storage device 80 such that the electric storage device 80 contains information for determining the amount of ink remaining in the ink container 12. As indicated by step 114, based on the ink remaining in the ink container 12 using the extraction characteristics, the controller 29 then selects a extraction rate. In the illustrated embodiment, the look-up table based on the ink extracted from the ink valley of 12 is used to determine the first extraction rate. To complete the desired decimation rate, the controller 29 adjusts the operations of the printing mechanism 96 and the print head 16 to select the printing operation to obtain the desired decimation rate. In this printing operation, the paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 584600 V. Description of the invention (the amount of ink broken from the ink container 12 is monitored, and the extraction rate is adjusted as required, In order to improve the ink extraction from the ink container 12. # The single-color ink container shown in FIG. 7 and the three-color ink container shown in FIG. 6 generally have different ink extraction characteristics. The single-color ink container is stored in the storage. The tank 34 has a larger portion, and therefore, when the ink is drawn, there will be different reaction force characteristics, and there is a smaller tank chamber in the storage tank 34 connecting the ink colors in the three-color ink container 12 For this reason, the look-up table connected to the monochrome ink container 12 and the look-up table connected to the three-color ink container 12 will have different values. The technology of the present invention saves the extraction characteristics to a connection to the ink container 12 Memory device. The printing system 10 utilizes second-class extraction characteristics to adjust the operation of the printing system to more fully extract ink from the ink container 12. By removing ink from the ink container 12, The more ink is drawn, the ink container does not need to be placed as usual, thereby reducing the printing cost per page of the printing system 10. Furthermore, the more ink is drawn from the ink container 12, the less it can enter the waste stream.
