Inkjet image forming apparatuses, such as inkjet printers, inkjet copiers, all-in-one inkjet printers, and the like, generally have an ink cartridge detachably mounted so that a consumer can replace the ink cartridge after the ink in the ink cartridge is consumed.
In order to record the state of the ink cartridges so as to facilitate the inkjet image forming apparatus to centrally manage the ink cartridges mounted thereon, a memory chip is mounted on the ink cartridges. The memory chip stores information on the ink cartridge, such as a product model, a sales area, an ink capacity, an ink remaining amount, an ink consumption amount, a color/type of ink, a date of manufacture, and the like. Furthermore, as the ink cartridge is used, some information, such as the remaining amount of ink and the amount of consumed ink, is automatically updated. When the ink in the ink cartridge is consumed, even if the user adds ink to the ink cartridge, the idea of recycling the ink cartridge is difficult to implement because the data in the memory chip has been identified that the ink cartridge has changed to a no ink state.
In view of environmental protection, a plurality of replaceable compatible memory chips appear on the market, so that after ink is added into the ink box which uses up the ink, a user only needs to install the replaceable memory chips at the same time, the ink box can be recycled, and the influence of the waste ink box on the environment is greatly reduced.
And an ink-jet head is arranged on part of the ink box, and a plurality of nozzles are arranged on the ink-jet head. When manufacturing these head-equipped ink cartridges with ink jet heads, manufacturers integrate a nozzle control part for controlling ink ejection and an information storage part storing information on the ink cartridges into the same die (obtained after wafer dicing) to obtain a memory chip, as shown in fig. 1, which can reduce manufacturing costs.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments and the features of the embodiments can be combined without conflict, and the technical solutions formed are all within the scope of the present invention.
Additionally, the steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
The nozzle control part of the ink box with the nozzle generally needs to bear higher driving voltage (16V-24V), so that the requirements on process and materials are high, the manufacturing precision is high, and the manufacturing cost is very high. In addition, the design life of the nozzle control part can often print ink with the capacity of several ink boxes, and if the ink in the ink box is printed, the nozzle control part is discarded along with the ink box, which undoubtedly causes great resource waste.
Fig. 2 shows a prior art head cartridge with an ink jet head.
As shown in fig. 2, the head cartridge includes a cartridge body 10, and the cartridge body 10 includes a bottom surface 12 and a mounting surface 11. The bottom surface 12 is located below the direction of gravity, and the mounting surface 11 is one side surface of the ink cartridge. A memory chip is also mounted on the cartridge and includes a flexible circuit board 21 and an electronic module 22. The flexible circuit board 21 is attached to the bottom surface 12 and the mounting surface 11. The electronic module 22 is disposed on a portion of the flexible circuit board 21 attached to the bottom surface 12. The flexible circuit board 21 is attached to the mounting surface 11, and a plurality of signal contacts 23 are provided, and the signal contacts 23 are connected to the electronic module 22 through wires (not shown) provided on the flexible circuit board 21.
The manufacturers of cartridges with heads must purchase new cartridges in order to maintain their own interest, after the ink in the cartridges has been consumed, and therefore impose certain technical limitations on the information storage portion of the electronic module 22. As a part of the information storage portion, information on the remaining amount of ink and/or the amount of ink consumption in the information on the ink cartridge is stored using, for example, an OTP (one time programmable) memory, a fuse count memory, or the like. The remaining information stored in the information storage portion, such as information on the product model, ink color, and the like in the information on the ink cartridge, and data of the nozzle control portion and the like, does not change during use, and thus can be stored using a ROM.
The one-time-rewritable memories such as OTP and fuse technology memories have a characteristic that data cannot be repaired after the inkjet image forming apparatus rewrites the data. For example, when the ink jet image forming apparatus writes information indicating that the ink cartridge has no ink remaining, such as "the amount of remaining ink is 0" to the information storage portion, the information on the amount of remaining ink cannot be restored to "the amount of remaining ink is 100%" or other information indicating that there is ink in the ink cartridge. After acquiring information indicating that the ink cartridge has no remaining ink, such as "the amount of remaining ink is 0", the inkjet image forming apparatus stops continuing the operation and prompts replacement of the ink cartridge.
In order to enable the ink cartridge with the nozzle which runs out of ink to be continuously utilized, the embodiment of the application adopts a repairing chip which is arranged on the ink cartridge with the nozzle, and the information connection between the information storage part of the information storage part, which is automatically updated along with the continuous use of the ink cartridge, such as the part of the ink residual quantity and/or the ink consumption quantity and the like, and the ink jet imaging equipment is disconnected by disconnecting the electric connection between the information storage part in the electronic module and at least one signal contact point in a plurality of signal contact points; or, the information which is automatically updated along with the continuous use of the ink box, such as the ink residual quantity and/or the ink consumption quantity, and the like, in the information about the ink box stored in the information storage part is destructively rewritten into the information which represents that the residual ink quantity of the ink box with the nozzle is 0, and the data in the repairing chip can replace part of the data in the information storage part in the electronic module to provide the residual ink quantity information for the ink-jet imaging device. Because the data stored in the repair chip replaces part of the data stored in the information storage part in the electronic module, the data stored in the information storage part in the electronic module cannot play a role in recording the state of the ink box with the nozzle, and even if the residual ink amount in the ink box is 0, the ink jet imaging device can continue to print according to the data stored in the repair chip without prompting to replace the ink box.
When the information connection between the information storage part and the ink-jet imaging device is disconnected, the repairing chip stores information of ink residual quantity and/or ink consumption, information of product model of the ink box, ink color and the like, and data of the nozzle control part. In this case, the data stored in the repair chip may completely replace the data stored in the information storage portion.
In the case of destructively rewriting the data stored in the information storage portion, since the information stored in the ROM memory is not rewritten, the repair chip stores at least information that is automatically updated with the continuous use of the ink cartridge among the information about the ink cartridge stored in the memory that is rewritten at one time in the information storage portion. Since the two chips provide the same address and the same data, the data sent to the inkjet image forming apparatus does not cause a conflict therefor. Therefore, in the embodiment of the present application, in a manner of destructively rewriting data stored in the information storage portion, the repair chip may include information such as a product model of the ink cartridge, an ink color, and the like, and data of the nozzle control portion, and the like, in addition to information of an ink remaining amount and/or an ink consumption amount.
Fig. 3 shows a repair scenario according to an embodiment of the present application.
As shown in fig. 3, the existing memory chip of the ink cartridge with head includes a nozzle control part and an information storage part. When the ink in the ink cartridge is used up, the information such as the remaining amount of ink and/or the amount of consumed ink stored in the information storage portion is rewritten by the inkjet image forming apparatus to the information such as "the amount of remaining ink is 0", "the amount of consumed ink is 100%" or "the amount of consumed ink" and the like, so that the information such as the remaining amount of ink and/or the amount of consumed ink stored in the information storage portion cannot play a role of continuing the recording of the state of the ink cartridge with the head.
The embodiment of the application adopts the mode that the ink box with the nozzle is connected with the repairing chip, and the repairing chip stores information (such as the content that the ink is consumed by less than 100 percent or the ink is not consumed) which indicates that the residual ink quantity in the ink box with the nozzle is not 0. The ink box with the spray head can be continuously used by replacing part or all of the information storage part in the original storage chip of the ink box with the spray head by adopting the information stored in the repair chip, so that the service life of the ink box with the spray head is prolonged, and the use cost of the ink box with the spray head is reduced.
As shown in fig. 3, the nozzle control section and the information storage section of the memory chip are connected to the inkjet image forming apparatus through a common bus including a DATA line DATA, a clock line CLK, and an address line ADD. It should be noted that the present invention is not limited to a head cartridge connected to an inkjet image forming apparatus using a common bus.
In the embodiment of the application, the repairing chip is mounted on the ink box with the nozzle, and the repairing chip can be mounted on the ink box body of the ink box with the nozzle. For example, the repair chip is mounted on the mounting surface of the cartridge body.
After the repair chip is mounted on the head cartridge, the repair chip is electrically connected to the signal contact point, and when the head cartridge is mounted in the inkjet image forming apparatus, the repair chip is also connected to the aforementioned common bus. Since the ink jet image forming device accesses the data stored in the information storage part through the address, after the repair chip with the same address as the original information storage part is connected to the common bus, the data sent to the ink jet image forming device are inconsistent, so that the conflict is caused, and the ink jet image forming device considers that the ink box with the nozzle is abnormal. Therefore, in order to avoid the occurrence of such a conflict, the embodiment of the present application disconnects the information read-write connection between the original information storage portion and the inkjet image forming apparatus while the repair chip is mounted. Since the nozzle control section of the memory chip exchanges data with the inkjet image forming apparatus through another nozzle selection signal line (not shown in fig. 1), this manner of disconnection does not affect communication between the nozzle control section and the inkjet image forming apparatus.
There are many ways to disconnect the information read-write connection between the original information storage part and the ink-jet imaging device. One way of achieving this is to cut off at least one DATA-carrying line of the electronic module from the flexible printed circuit board, which line connects the signal contacts. The cutting may be performed by a doctor blade or laser irradiation blowing.
Another possible implementation method is to hollow out at least one of the signal contacts connected to the wire DATA, and cover the corresponding signal contact of the repair chip on the hollowed-out signal contact, so as to replace the original signal contact to be electrically connected to the inkjet imaging device, as shown in fig. 4.
Fig. 4 shows one way of mounting the repair chip between the cartridge body and the flexible circuit board. This requires removing the flexible circuit board 41 from the cartridge body, mounting the repair chip 42 on the mounting surface of the head cartridge, and re-attaching the flexible circuit board 41 to the repair chip 42. Because the signal contact points are exposed on the front side and the back side of the flexible circuit board, the repairing chip can be attached between the flexible circuit board and the ink box body.
In the method of cutting off the DATA line DATA shown in fig. 3, the repair chip may be mounted between the cartridge body and the flexible circuit board, may be mounted on the original flexible circuit board, or may be mounted outside the cartridge body and the flexible circuit board. In the embodiment of the application, no matter where the repair chip is installed, the repair chip and the flexible circuit board can be fixed and electrically connected by adopting a fixed connection mode such as paste welding.
In the embodiment of the application, the regenerated ink box with the spray head obtained by the repairing method mainly comprises an ink box body, a flexible circuit board arranged on the ink box body, an electronic module arranged on the flexible circuit board and a repairing chip. The repairing chip stores information indicating that the residual ink quantity of the ink box with the nozzle is not 0. The flexible circuit board is provided with a plurality of signal contact points, and the repair chip is electrically connected to the plurality of signal contact points. The original electronic module comprises a nozzle control part and an information storage part which can be replaced by a repair chip without playing a role, and the repair chip is mainly used for replacing all or part of the information storage part in the electronic module. The information storage portion stores information indicating that the amount of ink remaining in the head cartridge is 0, or an open circuit is formed between the information storage portion and at least one of the plurality of signal contact points. Of course, it is also possible that the information storage portion stores information indicating that the amount of ink remaining in the head cartridge is 0, and that the information storage portion forms an open circuit with the at least one of the plurality of signal contact points.
In the embodiment of the present application, the repair chip is generally a memory that stores information about the head cartridge, such as a product model, a sales area, an ink capacity, an ink remaining amount, an ink consumption amount, a color/type and a production date of ink, cartridge identification information, a manufacturer, a production date, and a printed number of pages. The ink cartridge identification information may be recording material color information, a device address of a memory, or other information that can distinguish different types of ink cartridges with heads. The memory can adopt common nonvolatile memories, such as EPROM, EEPROM, FLASH, ferroelectric memory, phase change memory and the like; volatile memory plus power supply schemes such as SRAM + battery or capacitor, DRAM + battery or capacitor may also be employed.
In the ink box with the nozzle obtained by the repairing method, a lead between the information storage part and at least one signal contact point in the plurality of signal contact points is cut off; alternatively, the at least one signal contact of the plurality of signal contacts is hollowed out. The wire, which is cut off between the information storage portion and the at least one of the plurality of signal contacts, may be, for example, a data line in a common bus.
The information on the amount of ink remaining and/or the amount of ink consumed stored in the information storage portion may also be destructively rewritten by blowing the data unit in the information storage portion. After the data units in the information storage part are fused, the information of the ink residual quantity and/or the ink consumption quantity stored in the information storage part is the information which represents that the residual ink quantity in the ink box with the nozzle is 0.
Referring to fig. 5, the method of repairing the ink cartridge with head according to the embodiment of the present application may also be to destructively rewrite the information on the remaining amount of ink and/or the amount of consumed ink in the information storage portion of the electronic module, then mount the repair chip on the ink cartridge with head, and electrically connect the repair chip to a plurality of signal contact points on a flexible circuit board attached to the body of the ink cartridge.
How to destructively rewrite the information on the remaining amount of ink and/or the amount of consumed ink stored in the information storage portion of the head cartridge and the operation principle after mounting the repair chip will be described with reference to fig. 6A, 6B, and 7.
Fig. 6A and 6B are schematic diagrams showing a configuration of a data unit in which a fuse element (like a fuse) is used as an information storage portion to store information such as the amount of remaining ink and/or the amount of consumed ink, which is automatically updated as the ink cartridge is used. The DATA unit includes a pull-up resistor R and a fuse element E, the pull-up resistor R is connected in series with the fuse element E and then connected between a VCC high voltage and Ground (GND), and the read DATA line DATA is taken out between the pull-up resistor R and the fuse element E. When the fuse element E is not blown, the fuse element E corresponds to one conductive line. The read voltage of the DATA line DATA is therefore 0V, which can be defined as a one-bit (bit) binary DATA "0" and indicates that the ink in the cartridge is sufficient. When the ink jet image forming apparatus finds that the ink in the head cartridge has been exhausted by detection or calculation, an instruction to rewrite the data is issued to the information storage portion, and the fuse element E is blown by inputting a relatively large current to the fuse element E, as shown in fig. 6B. At this time, the DATA line DATA is connected to VCC via the pull-up resistor R, and a high level is output, which can be defined as a one-bit (bit) binary DATA "1" at this time and indicates that the ink in the ink cartridge is exhausted. Such an unrecoverable data rewriting method allows the inkjet image forming apparatus to read only "1" even if the user adds ink to the head cartridge when the head cartridge runs out of ink, and considers that the head cartridge runs out of ink.
Therefore, in the embodiment of the present application, the information for destructively rewriting the remaining amount of ink and/or the amount of ink consumption stored in the information storage portion of the head cartridge may be information indicating that the remaining amount of ink and/or the amount of ink consumption in the information storage portion is 0 by fusing the fuse element of the data unit of the information for the remaining amount of ink and/or the amount of ink consumption stored in the information storage portion. When the information storage portion does not use a fuse element to record information on the amount of ink remaining in the head cartridge, for example, a one-time programmable (OTP) or EPROM memory is used, and a data unit that records information on the amount of ink remaining in the head cartridge is a floating gate transistor (floatinggateFET), and data is recorded by turning on or off, and rewriting of data does not basically have recoverability. Destructive rewriting of the floating gate transistor can be achieved by applying a high voltage, for example, 24V, between the DATA line of the information storage portion and the ground GND, so that the floating gate transistor is blown and high level or high resistance state output of all DATA cells can be achieved.
In fig. 7, an embodiment of the present application is illustrated by taking a data unit (bit), which may be the fuse element, the floating gate tube, or the like. After the repair chip is mounted on the head cartridge, both the repair chip and the original information storage portion are simultaneously connected to the DATA line DATA. Therefore, when the DATA cell of the original information storage portion has been rewritten, the DATA cell is equivalent to an open circuit (open circuit), and the voltage of the DATA line is not pulled low; while the DATA cell (bit) in the repair chip is still connected between the VCC high voltage and Ground (GND), corresponding to a wire, the DATA line will discharge to ground through this wire, so that the voltage of the DATA line is still maintained at "0" V, which indicates that the ink in the cartridge is sufficient. Therefore, after the repair chip is installed, ink is added into the ink box, and the ink can still be identified and utilized by the ink-jet imaging equipment.
Because the information of the ink residual quantity and/or the ink consumption quantity in the original information storage part is subjected to destructive rewriting, even if the DATA line of the information storage part is not disconnected with the electric connection of the ink-jet imaging device, the ink-jet imaging device can be ensured to only access the repair chip, and the recycling of the waste ink box with the nozzle is realized. Of course, it is also possible to electrically disconnect the information storage portion from the plurality of signal contact points after destructively rewriting the DATA in the information storage portion, so that the electrical connection between the DATA line of the information storage portion and the inkjet image forming apparatus is disconnected.
The embodiment of the application makes full use of the nozzle control part in the original electronic module on the ink box with the spray head, and replaces the information storage part needing to be repaired, so that the waste ink box with the spray head can be recycled at low cost. Since the connection between the signal contact and the useless information storage portion is cut off or the useless information storage portion is destructively rewritten, even if the repair chip and the original storage portion are connected together through the bus line and the access address is the same, the original information storage portion does not affect the additional repair chip and the conflict of data inconsistency does not occur.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the technical solution of the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
