Description
Technical Field
The invention relates to the technical field of imaging equipment, in particular to a storage chip, an imaging box and imaging equipment.
Background
There are continuous ink supply systems available on the market for imaging devices, such as inkjet printers, and memory chips used with continuous ink supply systems are called permanent chips, which can be used continuously when the printed ink is exhausted by simply refilling the printer.
The permanent chip implementation in the current market is to store multiple sets (generally more than 10 sets) of data inside the chip, and the data may include: an image forming cartridge manufacturer code, a production date, a model, a characteristic parameter, the number of image forming pages, recording material remaining amount information, a serial number, and the like. The permanent chip can find that the ink is exhausted, when the printer communicates with the permanent chip again after the user fills the ink, the permanent chip replaces another set of brand new data (including the serial number) to interact with the printer, and the residual capacity of the printer is tested to recover 100%, so that the printer can be continuously used. Because at least more than 10 different serial numbers and corresponding data need to be stored in the current permanent chip, a large storage space of the permanent chip needs to be consumed, and the communication and control process between the permanent chip and the printer is complex, difficult to realize and low in universality due to the switching of a plurality of sets of data. After the existing permanent chip finishes using a plurality of sets of data stored in the chip, the chip needs to be discarded, and the continuous supply system can be continuously used only by replacing the new permanent chip. For example, 10 sets of data are stored in the permanent chip, and after the 10 sets of data are used once, the permanent chip cannot be normally used by the imaging device, and a new permanent chip needs to be replaced.

Drawings
The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a schematic structural diagram of a memory chip according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A memory chip, an imaging cartridge, and an imaging apparatus according to an embodiment of the present invention are described below with reference to fig. 1.
Fig. 1 is a schematic structural diagram of a memory chip according to an embodiment of the present invention. As shown in fig. 1, the memory chip 100 includes: a storage unit 110 and a processing unit 120.
The storage unit 110 stores first chip data and second chip data.
In a specific example, the storage unit 110 is, for example, a nonvolatile memory. The first chip data and the second chip data may be chip data for interfacing the memory chip with an imaging device, such as a printer. It will be appreciated that the first chip data and the second chip data comprise, for example, serial numbers and correspondingly other relevant data for communication. Therefore, in the embodiment of the present invention, the memory chip 100 can only store two sets of chip data, and compared with the existing method that more than 10 sets of chip data need to be stored, the embodiment of the present invention has a lower requirement on the storage space of the memory chip 100, thereby reducing the storage space required by the chip.
The processing unit 120 is connected to the storage unit 110, and configured to monitor a data variation of the first chip data or the second chip data when performing communication according to the written first chip data or the written second chip data, and switch the second chip data or the first chip data to perform communication when the remaining capacity data of the first chip data or the second chip data is greater than or equal to a first preset capacity threshold.
In a particular embodiment, the memory chip 100 is, for example, a permanent chip.
Therefore, the embodiment of the invention can realize repeated use through two sets of chip data, thereby reducing the storage space required by the chip, and needing no multiple sets of chip data, simplifying the communication and control process, being easy to realize and having strong universality.
In a specific embodiment, the memory chip 100 (e.g., a permanent chip) may be connected to an imaging device, such as a printer, and the processing unit 120 writes the first chip data or the second chip data. When the printer is powered on and operated, the first chip data can be used as current communication data, and the second chip data can be used as standby data. The printer reads the first chip data, communicates with the memory chip 100 through the first chip data, during the communication process, the residual capacity data of the first chip data is acquired, because the consumption of the first chip data is gradually reduced during the use process, when the remaining capacity data of the first chip data gradually decreases and approaches a first preset capacity threshold (the first preset capacity threshold may be 85% of the remaining capacity data of the total capacity), such as less than or equal to 85%, the memory chip 100 disconnects the communication with the printer, i.e., stops communication with the printer, and when or before the memory chip 100 re-communicates with the printer, i.e., the memory chip 100 is powered up again, to switch to the second chip data to communicate with the printer, or the second chip data is used as the current communication data, so that the memory chip 100 normally communicates with the printer according to the second chip data. After the second chip data is used as the current communication data, the memory chip 100 restores the first chip data to the original state, and the first chip data is used as the spare data. When the second chip data is used as the current communication data, the first chip data is used as the standby data. After the remaining capacity data of the second chip data gradually decreases and approaches the first preset capacity threshold, the memory chip 100 disconnects communication with the printer, and switches the first chip data to current communication data after or before the memory chip 100 reestablishes communication with the printer; the second chip data is automatically reset to the original value and switched to the standby data. Thus, the first chip data and the second chip data are recycled, so that the memory chip 100 can be recycled for multiple times. When the memory chip 100 is mounted on an imaging cartridge (toner cartridge or ink cartridge), the imaging cartridge can be reused many times as long as developer (toner or ink) is present in the imaging cartridge. Preferably, when the remaining capacity data of the first chip data is equal to the first preset capacity threshold, the memory chip 100 disconnects the communication with the printer, and the frequency of switching the first chip data and the second chip data in the memory chip 100 is reduced, so as to improve the service life of the memory chip 100.
The way in which the processing unit 120 disconnects the memory chip 100 from the imaging device, such as a printer, may include the following: a. the memory chip 100 sends an instruction that cannot be recognized by the printer or an instruction that is not currently needed by the printer (i.e., a preset error code) to the printer, causing the printer to stop or interrupt communication with the memory chip; b. disconnecting the memory chip 100 from the printer, for example, when the memory chip is in communication with the printer, the contact terminal of the memory chip 100 is in contact with the contact terminal of the main board in the printer, and when the memory chip is disconnected, the contact terminal of the memory chip 100 is separated from the contact terminal of the main board in the printer; c. powering down the printer and/or the memory chip 100 results in a disconnection of communication between the memory chip 100 and the printer. The unrecognized instruction in the mode a may refer to: when the printer communicates with the memory chip 100, the printer's preset response instructions do not include the instructions, and in either case the chip sends the unrecognized instructions to the printer, the printer will stop or interrupt communication with the memory chip. The instructions not currently needed by the printer may refer to: for example, the printer currently requires an instruction to send the remaining capacity data to the memory chip 100, but the memory chip sends the version number data, and when the printer receives the version number data, the printer stops or interrupts communication with the memory chip 100.
The way of the memory chip 100 to communicate with the printer again may include the following ways: when the memory chip 100 disconnects the communication with the printer in the manner a, if the printer does not stop the communication with the memory chip 100 and only interrupts the current communication process, the printer may resend the communication instruction, and when the memory chip 100 receives the instruction for resending the communication by the printer, the memory chip 100 resends the normal data to the printer, thereby completing a new communication; if the printer has stopped communicating with the memory chip 100, the need to re-communicate is present in such a way that the memory chip 100 is powered up again as described below. When the memory chip 100 is disconnected from communication with the printer in the manner b, the re-communication may be implemented in such a manner that the memory chip 100 is powered back on as described below; the memory chip 100 may be configured to perform communication in such a manner that the communication with the printer is disconnected and then the power is turned on and turned on in the c-th mode. When the memory chip 100 disconnects the communication with the printer in the b-th mode, the power is supplied to the printer again, and the printer is started to realize the communication again.
The first preset capacity threshold is an empirical value, and the value of the first preset capacity threshold can be set according to the requirements of the printer, for example, and the first preset capacity thresholds corresponding to different printers may be different. The first preset capacity threshold is a threshold at which the memory chip 100 can be normally reset, and after the normal reset, the memory chip 100 can be verified by the image forming apparatus (printer) and normally used. Preferably, after the normal reset, the memory chip 100 can be authenticated by the image forming apparatus (printer) and the memory chip 100 is normally used as a brand-new chip. For example, a normal reset may refer to: if the first chip data or the second chip data exceeds the first preset capacity threshold, the printer will not normally use the first chip data or the second chip data of the memory chip 100 even if the memory chip 100 restores the first chip data or the second chip data to the original value. In a specific embodiment, the first preset capacity threshold is, for example, greater than or equal to 85% of the total capacity of the chip data. That is, when the remaining capacity data of the first chip data or the second chip data is close to 85% of the total capacity or higher than 85% of the total capacity, for example, the remaining capacity data of the first chip data or the second chip data is 85.5% or 86%, etc. (which may be specifically set according to actual requirements), the switch is made to the second chip data or the first chip data.
For example, the chip data currently written in the memory chip 100 is first chip data, that is, the memory chip 100 and the printer are to communicate with each other through the first chip data, the printer verifies the first chip data first, after the verification is completed, the memory chip 100 and the printer communicate with each other through the first chip data, when the remaining capacity data of the first chip data is decreased and approaches a first preset capacity threshold, the memory chip 100 actively interrupts the communication process with the printer, and switches the first chip data to second chip data, that is, the second chip data is used as communication data, when the memory chip 100 and the printer communicate again, the printer verifies the second chip data, and then communicates with the memory chip 100 through the second chip data, and at the same time, the memory chip 100 recovers the remaining capacity data in the second chip data to 100%. Similarly, when the remaining capacity data of the second chip data is decreased and approaches the first preset capacity threshold, the memory chip 100 actively interrupts the communication process with the printer, and switches the second chip data to the first chip data, that is, the first chip data is used as the communication data, when the memory chip 100 communicates with the printer again, after the printer verifies that the first chip data is completed, the memory chip 100 communicates with the first chip data by using the first chip data, and at the same time, the memory chip 100 restores the remaining capacity data in the first chip data to 100%. Furthermore, through the process, the repeated use can be realized through two sets of chip data, so that the storage space required by the chip is reduced, a plurality of sets of chip data are not needed, the communication and control process is simplified, the realization is easy, and the universality is strong.
In one embodiment of the present invention, the processing unit 120 is further configured to: recording the number of times of switching chip data of the memory chip 100, and when the number of times of switching chip data reaches a preset number, not switching the current chip data until the remaining capacity data of the current chip data is reduced to a second preset capacity threshold, wherein the second preset capacity threshold is smaller than the first preset capacity threshold.
The second preset capacity threshold is, for example, 0, that is, the data of the current chip is completely consumed, the data of the remaining capacity of the current chip is 0, and at this time, the chip cannot be used any more and needs to be replaced with a new chip.
In one embodiment, the predetermined number is an empirical value, which is set based on determining the current consumption level of the chip as accurately as possible. When the switching times reach the preset times, the chip is considered to be consumed greatly and needs to be replaced.
For example, the number of times of switching chip data may be set, when the recorded number of times of switching chip data reaches a preset number, even if the remaining capacity data of the chip data is close to or reaches a first preset capacity threshold, if 85%, another group of chip data may not be switched again until the remaining capacity data in the current chip data is reduced to a second preset capacity threshold, if 0, the current chip is rejected by the printer, and a new chip needs to be replaced, so that the problem that the performance of the chip is reduced due to long-term use, and the use effect is affected is effectively avoided.
In an embodiment of the present invention, the processing unit 120 is specifically configured to: and obtaining the residual capacity data of the first chip data or the second chip data according to the written coverage rate data of the memory chip 100.
In one embodiment of the present invention, the way to power up the memory chip 100 again includes: the cover is closed after the cover of the image forming apparatus connected to the memory chip 100 is opened, or the power of the image forming apparatus is turned on after the power of the image forming apparatus is turned off. Specifically, for example, the cover of the imaging device may be opened by a user and then closed, so that the imaging device is powered on after being powered off, power-off restart is realized, and then the memory chip 100 is powered on after being powered off; or, the user turns on the power supply after turning off the power supply of the imaging device, and if the imaging device is unplugged and plugged into a power socket, the imaging device is powered off and restarted, so that the memory chip 100 is powered on after being powered off.
It will be appreciated that current imaging devices, such as printers, operate with chips that store more than 10 serial numbers and associated data, and that it is not possible to restore 100% of the chip's data capacity by reinitializing the data when the remaining capacity data is below 85%. Based on this, in the specific embodiment of the present invention, taking the imaging device as an example of a printer, the memory chip 100 (e.g. a permanent chip) only needs to store two sets of serial numbers and corresponding data (i.e. the first chip data and the second chip data), and the chip is enabled to record the remaining capacity data of the chip close to 85% by judging the coverage data written by the chip (when the remaining capacity data is greater than or equal to 85%, the printer does not record the serial number and the remaining capacity data corresponding to the serial number, and when the remaining capacity data is greater than or equal to a first preset capacity threshold, the memory chip 100 disconnects communication with the printer, because the printer does not record the remaining capacity data of the memory chip 100, after switching to another set of chip data, after resetting, the chip data is switched back to continue communication with the printer, the chip data switched back can still be considered as brand new data in the memory chip 100, and once the printer records the serial number and the corresponding serial number below 85%, the corresponding data If the residual capacity data of the chip is recovered to 100% at this time, the printer can also consider that the chip has been modified or used to report an error) when the chip is powered on again, the connection between the memory chip 100 and the printer is disconnected, printing is forced to report an error, and after the error is reported, a user only needs to switch on or off the printer cover once, namely after the printer is restarted, the 100% data capacity can be recovered.
Specifically, the principle of chip reuse may be: when a printer cover is opened or closed or a printer is opened or closed, because the memory chip 100 is disconnected from the printer, the memory data of the memory chip 100 is lost, after the power is turned on again, the memory chip 100 switches another serial number (for example, the current communication data is switched from the first chip data to the second chip data), and corresponding full new data (second chip data) is copied into the memory, which is equivalent to a set of completely new data is switched on, because the printer does not record the serial number (first chip data) before switching and corresponding residual capacity data when switching another serial number (second chip data), even if only two sets of chip data are switched in a circulating manner, the printer considers that the memory chip 100 is a completely new chip, and the residual capacity data is 100%. Of course, it is also possible to realize that the chip data in the memory chip 100 is larger than two sets, and the printer will consider the memory chip 100 as a brand new chip when the chip data is switched every time. In other words, in the embodiment of the present invention, the percentage of the remaining capacity data cannot reach the value recorded by the printer, for example, greater than or equal to 85%, at this time, the memory chip 100 actively or passively disconnects from the printer, for example, stops communication with the printer or sends an error code to make the printer report an error, and after the printer is powered off and restarted, the memory chip 100 automatically resets the data capacity, so as to achieve the purpose of being reusable. The memory chip 100 is actively disconnected from the printer, and the disconnection of the memory chip 100 from the printer can be realized by referring to the aforementioned a-way. The memory chip 100 is passively disconnected from the printer, and the disconnection of the memory chip 100 from the printer may be implemented by referring to the above-mentioned b-th or c-th mode.
In one embodiment of the present invention, the memory chip 100 further includes a memory (not shown). Because the memory has the characteristic that under the preset condition (the power of the memory chip 100) data can be automatically cleared (or lost), at least one of the first chip data and the second chip data is written into the memory by the nonvolatile memory during communication, after the memory chip 100 is disconnected from the imaging device, the data in the memory is lost, and the residual capacity data in the first chip data and the second chip data is greater than or equal to the first preset capacity threshold, so that the data can be written into the memory for multiple times, and the imaging device does not record the first chip data and the second chip data, so that the memory chip 100 can still be normally used by the imaging device after being reset for multiple times.
Specifically, the memory is used for copying and erasing the written first chip data and/or second chip data, and the first chip data and/or second chip data in the memory are used for communication. That is, the imaging device reads the first chip data and/or the second chip data from the memory to communicate with the memory chip 100. That is, the first data chip and/or the second data chip stored in the storage unit 110 are copied (i.e., written) to the memory, so that the imaging device reads the first chip data and/or the second chip data from the memory. Preferably, the current communication data is usually written into the memory, so that the changed data is only the data in the memory, and when the predetermined condition is reached, the current communication data in the memory is lost. When the memory is powered on again, the other chip data in the nonvolatile memory is written into the memory for communication again during communication, and the written data is completely new data serving as current data for communication. When the imaging device is disconnected from the memory chip 100, the memory chip 100 erases current and previous communication data, such as first chip data or second chip data, from the memory, so that after the chip data are switched, the second chip data or the first chip data are written into the memory again.
Because the erasing times of the existing nonvolatile memory are limited, the erasing times of the memory chip 100 cannot be met, and a common method at present is to open up a plurality of spaces for storing data, which poses a challenge to the size of a chip storage space. Based on this, the embodiment of the present invention provides the memory, the data to be erased (i.e., the first chip data and the second chip data) is copied from the nonvolatile memory, i.e., the storage unit 110, to the memory, and the data is read from and written into the memory each time the data is print-accessed, and the memory has the characteristics of unlimited number of times of reading and writing and fast reading and writing, so that the memory chip 100 has permanent erasing times.
In an embodiment of the present invention, the memory is further used for storing communication data between the memory chip 100 and the imaging device. That is, all data generated during the communication of the memory chip 100 with the imaging device is stored in the memory. It can be understood that, during the communication process between the imaging device, such as a printer, and the chip, a large amount of data is written into the chip, which puts requirements on the number of times of erasing and writing the memory of the chip, and if permanent erasing and writing are to be performed, the chip needs to have unlimited times of erasing and writing. In the embodiment of the present invention, all data generated during the communication between the memory chip 100 and the printer is stored in the memory, and the data in the memory is lost after the communication is disconnected and is not recorded by the printer, so that the printer can always think that the chip is not erased, and thus unlimited data erasing can be realized, and the memory has a large storage capacity and a high read-write speed, and can store a large amount of communication data, and the requirement for the storage space of the storage unit 110 is also reduced.
In an embodiment of the present invention, the processing unit 120 is further configured to: when receiving an ink quantity error signal sent by an image forming device such as a printer, the current chip data is switched, so that the problem that the printer reports errors when the non-standard ink quantity is exhausted can be solved. It will be appreciated that the run-in system requires the user to add ink, which may result in the amount of ink added being less than or more than the standard capacity, i.e., the non-standard amount of ink. The memory chip on the market can only switch serial numbers and data when the standard ink amount is exhausted, and the printer can report errors when the non-standard ink amount is generated, and the serial numbers cannot be automatically switched under the non-standard ink amount. The embodiment of the invention can solve the problem of error report of the printer when the nonstandard ink amount is exhausted. When the situation of non-standard ink amount occurs, only another chip with different serial numbers needs to be reloaded to be operated, when an ink amount error reporting signal sent by the printer is received, the communication with the printer is actively disconnected, the current chip data is switched, if the current chip data is the first chip data or the second chip data, the communication is switched to the second chip data or the first chip data, and therefore the problem that the printer reports errors when the non-standard ink amount is exhausted can be solved. In a specific example, the switching of the current chip data can be realized by switching the printer cover on and off once, that is, switching the printer off and restarting the printer, and powering on the memory chip 100 again.
For example, when the ink is abundant, the memory chip 100 closes the communication interface when the coverage value accumulated in the printing process exceeds a threshold (e.g., a first preset capacity threshold), and disconnects the communication with the printer, so that the printer reports an error, "no cartridge is installed", and at this time, the printer cover needs to be opened or closed only once, and the printer is powered off and restarted, so that the current chip data can be switched, the remaining capacity data of the memory chip 100 is recovered to 100%, and at this time, the error is released, and the printing task continues.
When the ink runs out, the printer can prompt the ink box with the corresponding color to report the error, at the moment, only the ink needs to be filled, and the printer cover is opened and closed or the printer is opened and closed once, so that the printer is powered off and restarted, the switching of the current chip data can be realized, the residual capacity data of the storage chip 100 is recovered to 100%, the error is reported at the moment, and the printing task is continued.
