Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of systems and methods that are consistent with aspects of the present application as detailed in the accompanying claims.
The printing system has replaceable components that provide printing material to the system, such as an imaging cartridge that contains toner, and an electrical storage device mounted on the imaging cartridge. In the prior art, a toner residual quantity detection device, such as a sensor, is arranged in the imaging box, and the toner residual quantity is detected by the sensor, so that when the toner is consumed, printing is stopped in time, and the problem of damaging a printing head is prevented. However, during actual use, the sensor may malfunction, resulting in inaccurate detection results, and when the actual toner is exhausted and the sensor feeds back the remaining toner, the printer continues to perform printing operations, resulting in a print head that is empty and has a risk of damaging the print head. In addition, manufacturers have been designed to save costs by removing the electrical storage device from the imaging cartridge for reuse and removing the sensor from the replaceable component to add a dummy sensor that is used to give a feedback signal to the printer that the toner is in a full toner condition, and to shield the printer from actually detecting the remaining toner level, in which case the actual toner is exhausted but the sensor feeds back the remaining toner.
In order to solve the above-mentioned problem, according to the embodiment of the present application, by predicting the detection result of each sensor and obtaining the detection result of the target sensor, and comparing the detection result of the target sensor with the corresponding prediction detection result, it can be determined whether the imaging box is abnormal, so as to avoid the situation that the sensor is faulty, or the detection result of the remaining toner caused when the sensor is a virtual sensor is inaccurate, and then the print head may be damaged due to the empty printing of the print head.
In order to better describe the detection method of the imaging box provided by the application, first, the structure of the imaging box and the detection method of the toner residual quantity in the imaging box will be briefly described in the application:
fig. 1 is a schematic structural diagram of an imaging box according to an embodiment of the present application, as shown in fig. 1, the imaging box 1 includes: a receiving chamber 11 for receiving toner, which may be ink or toner; the printer comprises a chip 12, wherein the chip 12 at least stores relevant information of a sensor, and the printer acquires the relevant information of the sensor through communication with the chip 12; a plurality of sensors 13, that is, a sensor 131, a sensor 132, a sensor 133, a sensor 134, and a sensor 135 shown in fig. 1, each of which can be used to detect the presence or absence of toner, are provided in the accommodating chamber 11 in the gravitational direction, wherein the sensors may be various types of sensors such as a capacitor, a detection electrode, a temperature sensor, and the like.
Since the toner moves toward the bottom of the accommodating chamber 11 by gravity, the sensors 131 to 135 are uniformly distributed in the direction of gravity so that it is possible to detect whether there is toner at different positions of the accommodating chamber 11.
In actual use, as toner is consumed, first, the sensor 131 provided at the upper portion of the accommodating chamber 11 does not detect toner, and then the sensor 132, the sensor 133, and the sensor 134 are sequentially provided up to the sensor 135. When all the sensors 13 detect no toner, it is indicated that there is no toner in the accommodating chamber 11; and when all the sensors 13 detect that toner is present, it means that the accommodating chamber 11 is filled with toner; further, when the sensor 131 does not detect toner and the sensor 132 to the sensor 135 can detect toner, it indicates that the remaining amount of toner is 80% or the consumption amount of toner is 20%.
After each sensor 13 completes the detection of the toner in the accommodating chamber 11, the corresponding detection result is sent to the chip 12, so that the chip 12 updates the toner remaining amount information currently stored by the sensor 13 according to the detection result.
Fig. 2 is a flow chart illustrating a detection method of an imaging box according to an embodiment of the present application, where the detection method shown in fig. 2 is adapted to the imaging box structure shown in fig. 1.
As shown in fig. 2, the method in the embodiment of the present application includes:
and 203, determining whether the target sensor is abnormal according to the detection result of the target sensor.
If a virtual sensor is present in the image forming cartridge, the virtual sensor is generally not based on the actual toner capacity in the accommodating chamber but based on the toner remaining amount information currently stored in the chip when detecting the toner.
For example, in fig. 1, the toner capacity in the accommodating chamber is 80%, the toner remaining amount information currently stored in the chip is 100%, and when the control sensor 131 detects whether the toner is present or not, it can be determined whether the ink cartridge is provided with a virtual sensor; if the detection result is that there is toner (i.e., it is consistent with the currently stored toner balance information in the chip), then the sensor 131 is a virtual sensor; if the detection result is that there is no toner (i.e., it is consistent with the actual toner capacity in the receiving chamber), then the sensor 131 is a physical sensor.
Based on the above detection characteristics of the sensor, in the embodiment provided herein, first, the toner remaining amount information currently stored by the chip is modified. Then, at least one target sensor in the imaging cartridge is controlled to perform detection to obtain a detection result. Finally, whether the target sensor is abnormal or not is determined based on the detection result.
For example, before modification, the toner remaining amount information currently stored by the chip is 100% (at this time, the toner in the accommodating chamber is 100%), at this time, the currently stored toner remaining amount information may be modified to 80%, and then, the detection is performed by the control including the target sensor 131, to obtain a detection result. When the detection result is that there is toner (i.e., the toner capacity in the accommodating chamber is kept consistent), then the sensor 131 is a true sensor; if the detection result is that there is no toner (i.e., consistent with the current toner capacity in the modified chip), then the sensor 131 is a virtual sensor.
By means of the method, the state (whether the sensor is a real sensor) of the sensor in the imaging box can be rapidly judged, so that the technical problem that whether the sensor in the imaging box is a virtual sensor cannot be determined in the prior art is solved, and the damage risk to the printer caused by the fact that the virtual sensor is arranged in the imaging box is avoided.
In an alternative embodiment, before modifying the toner remaining information currently stored in the chip, the method further includes: and selecting at least one target sensor from the plurality of sensors according to the currently stored toner remaining amount information, and obtaining a detection result of the target sensor.
Specifically, before the toner remaining amount information is modified, the target sensor may be controlled to perform detection once, so as to obtain a detection result of the target sensor before the toner remaining amount information is modified. The detection result before the toner remaining amount information is modified may be used to compare with the detection result after the modified toner remaining amount information to determine whether the target sensor is abnormal.
Wherein optionally, the determining whether the target sensor is abnormal according to the detection result of the target sensor includes: and comparing detection results of the same target sensor before and after the toner residual information currently stored by the chip is modified to determine whether the target sensor is abnormal.
Illustratively, when the pre-modification toner remaining amount information is 100%, the sensor 131 is selected as the target sensor and performs detection to obtain a first detection result, and at this time, the first detection result of the sensor 131 under the currently stored toner remaining amount information is toner. Modifying the toner remaining amount information to 60%, and controlling the target sensor 131 again to perform detection to obtain a second detection result; and comparing the first detection result with the second detection result. If the second detection result of the sensor 131 is the same as the first detection result, it may be determined that the sensor 131 is an entity sensor; if the second detection result and the first detection result of the sensor 131 are different, the sensor 131 may be determined to be a virtual sensor.
If the target sensor is 1, when the currently stored toner remaining amount information is modified, the modification of the toner remaining amount information should cause different detection results to appear before and after the modification if the target sensor is a virtual sensor.
In order to ensure the accuracy of the detection result, the toner remaining amount information currently stored in the modification chip is modified without toner consumption by performing the printing operation. In the actual use process, when the currently stored toner residual information is not modified, the detection result of the entity sensor corresponds to the current toner residual information stored by the chip, and the sensor with the detection result possibly changed before and after the toner residual information is modified is selected by taking the detection result as a reference; if the toner remaining amount is modified when the printing operation is performed without updating the toner remaining amount information, the sensor may not be accurately selected, resulting in an inability to correctly determine whether the sensor is a physical sensor. Based on the above, the modification of the toner remaining amount information currently stored by the chip in the embodiment of the present invention is performed without consuming toner by performing the printing operation. The printing consumption operation is not executed, and the printing operation is not executed on a brand-new ink box, or the used ink box is executed for updating the toner residual information in the last printing operation, but the next printing operation is not executed.
Or, alternatively, when the number of the target sensors is 2, when determining whether the target sensors are abnormal according to the detection results of the target sensors, whether the two target sensors are abnormal may also be determined based on the detection results of the two target sensors.
That is, the detection results of the two target sensors after modifying the toner remaining amount information currently stored by the chip are compared to determine whether the target sensors are abnormal. For example, before the residual information of the chip is modified, the residual information of the chip is read to be 80%, the sensor 131 and the sensor 132 are selected to execute the detection of whether the toner exists or not, the detection result of the sensor 131 before the modification and the detection result of the sensor 132 are obtained, the detection result of the sensor 131 and the detection result of the sensor 132 are different (the detection result of the sensor 131 is that the toner exists, and the detection result of the sensor 132 is that the toner does not exist); the remaining amount information of the chip is modified to be 50% or 100%, and the sensor 131 and the sensor 132 are again controlled to perform detection of the presence or absence of toner, to obtain a detection result of the sensor 131 and a detection result of the sensor 132 after modification.
If the detection result of the sensor 131 and the detection result of the sensor 132 after modification are different (the detection result of the sensor 131 is that there is toner and the detection result of the sensor 132 is that there is no toner), it is indicated that the sensor 131 and the sensor 132 are both physical sensors; conversely, if the detection result of the sensor 131 and the detection result of the sensor 132 after modification are the same (the detection result of the sensor 131 is toner-free and the detection result of the sensor 132 is toner-free, or the detection result of the sensor 131 is toner-free and the detection result of the sensor 132 is toner-free), it is indicated that the sensor 131 and the sensor 132 are virtual sensors.
In addition, on the basis of the above embodiment, optionally, in order to complete the rapid detection of the target sensor and improve the detection efficiency, the pre-detection of the target sensor may be performed according to the currently stored toner remaining amount information, so as to obtain a prediction result, and it may be determined whether the modification step needs to be performed based on the prediction result and the detection result before modification.
Specifically, at least one target sensor is selected from the plurality of sensors according to the currently stored toner remaining amount information, and a prediction result and a detection result of the target sensor are obtained; and judging whether the predicted result of the target sensor is consistent with the detected result, if so, executing the step of modifying the toner residual information currently stored by the chip, otherwise, not executing the step of modifying the toner residual information currently stored by the chip.
Illustratively, before the toner remaining amount information is modified, the toner remaining amount information of the chip is read, assuming that the toner remaining amount information is 70%, the sensor 132 is selected as a target sensor, a prediction result is obtained, at this time, the prediction result of the sensor 132 is that toner is present, and the sensor 132 is controlled to perform detection of whether toner is present or not, so as to obtain a detection result before the modification.
If the detection result before modification is the same as the prediction result (i.e. the detection result before modification is also toner), the residual information of the modified chip is 50%, the sensor 132 is controlled again to perform detection of whether toner is present or not, the detection result after modification is obtained, and whether the detection result after modification is consistent with the detection result before modification is compared.
If the detection result before modification and the prediction result are different (i.e. when the detection result before modification is that there is toner), the step of modifying the toner remaining amount information currently stored by the chip is not performed.
In addition, in order to further increase the detection speed of whether the sensor is a virtual sensor or not, the rapid detection of the sensor may be performed as follows:
optionally, if the currently stored toner remaining information of the chip indicates that the toner is not depleted, modifying the currently stored toner remaining information of the chip to data representing that the toner is depleted; then, a sensor located at the end in the gravity direction is selected as the target sensor, and the target sensor is controlled to detect whether toner is present or not, and whether the target sensor is abnormal or not is determined based on the detection result of the target sensor.
Illustratively, before modifying the toner balance information, the toner balance information of the chip is 70%, i.e., not 0%, and then it is determined that the toner balance information indicates that the toner is not depleted; at this time, the toner remaining amount information of the chip may be directly modified to 0%, and the sensor 135 may be set as a target sensor to detect whether or not toner is present.
Since the sensor 135 is the sensor closest to the bottom of the accommodating chamber, the detection result of the sensor 135 should be the presence of toner as long as the toner is not consumed, and therefore, after the detection, if the detection result of the sensor 135 is the presence of toner, it is indicated that the sensor is a physical sensor, and vice versa.
Optionally, the chip of the imaging box also stores usage status information of the imaging box, and the usage status information can be used for indicating whether the imaging box is used or not. With this usage state, the rapid detection of the sensor can also be performed in the following manner:
if the use state of the imaging box is unused, modifying the currently stored toner residual information into data representing toner exhaustion; at least one sensor of the plurality of sensors is randomly selected as the target sensor, a detection result of the target sensor is obtained, and whether the sensor is abnormal or not is confirmed according to the detection result of the target sensor.
For example, before modifying the toner remaining amount information, the reading chip knows that the usage state of the image forming cartridge is unused. At this time, the toner remaining amount information of the chip may be directly modified to 0%, and any one or more of the sensors 131 to 135 may be selected as a target sensor, and then the target sensor may be controlled to perform detection of the presence or absence of toner.
Taking the example of the target sensor being sensor 132, the imaging cartridge should be filled with toner since it is unused. Therefore, after the above detection, if the detection result of the sensor 132 is that there is toner, it is indicated that the sensor is a physical sensor, and vice versa.
In the above embodiment, when the printer detects that the ink cartridge is a new ink cartridge, the printer detects that the flag bit indicating that the ink cartridge is a new ink cartridge is present in the chip, and when the printer does not consume toner, the printer modifies the residual information in the chip to 0, randomly selects any one of the plurality of sensors as the target sensor, and performs detection of whether toner is present or not, so that the target sensor does not need to be selected according to the residual information, but a random selection manner is adopted, and the detection efficiency is improved.
On the basis of the above embodiment, the determination of the detection result may be implemented by a logic operation, and optionally, before modifying the toner remaining amount information currently stored in the chip, all the detection results of the sensors are obtained, and the logic operation is performed to obtain a first operation result; modifying the toner residual information currently stored by the chip into data representing toner exhaustion, and controlling all the sensors to detect whether toner exists or not; obtaining detection results of all the sensors again, and executing logic operation to obtain a second operation result; and confirming whether the sensor is abnormal or not according to the first operation result and the second operation result.
It is known that if the detection result or the operation result of the target sensor before and after the modification of the toner remaining amount information currently stored in the chip is the same, the target sensor is not abnormal.
For example, each sensor is provided with a flag bit for indicating the presence or absence of toner, with toner of "1" and no toner of "0"; the printer reads the flag bits of all the sensors to perform or operation, and if the toner still exists in the imaging box, or the result of the operation (and operation) is 1, the modified toner residual information is 0, and the flag bits of the sensors are read again to perform or operation, if the result of the operation is 1, the entity sensor is indicated, and if the structure of the operation is 0, the virtual sensor is indicated.
For example, before modification, the flag bits of all the sensors are read as 01111, and an OR operation is performed to obtain 1 (a first operation result); if the mark bits of all the sensors are 01111 after modification, performing OR operation to obtain 1 (second operation result), wherein the sensors are real sensors because the first operation result is the same as the second operation result; if the flag bit of all the sensors is 00000 after modification, performing OR operation to obtain 0 (second operation result), wherein the sensors are virtual sensors due to the fact that the first operation result and the second operation result are different.
Or the printer sends an instruction for reading all detection results of the sensors, if the sensors return to a high level, the detection results indicate that the toner exists, and if the sensors return to a low level, the detection results indicate that the toner does not exist, and all acquired toner results are input into a logic operation circuit to obtain a first operation result; modifying the toner residual information to 0, re-sending instructions for reading all the detection results of the sensors, and inputting all the obtained toner results into a logic operation circuit to obtain a second operation result; if the first operation result and the second operation result are the same, the sensor is a real sensor, and if the first operation result and the second operation result are different, the sensor is a virtual sensor.
On the basis of the foregoing embodiment, after the detection of the sensor is completed, the residual information needs to be restored, so as to avoid subsequent use errors.
Alternatively, the information may be backed up before the toner remaining information of the chip is modified, so that quick recovery of the toner remaining information (i.e., recovery directly by backup) may be performed after detection. Specifically, the currently stored toner remaining information may be backed up; and after the target sensor is determined to be abnormal according to the detection result of the target sensor, writing the backed-up toner residual information into the chip and covering the modified toner residual information. By backing up this information, the recovery speed of the toner remainder information can be improved directly by backup recovery after determining that the sensor is a true sensor.
Alternatively, the method of backing up the toner residual information may be omitted, that is, after determining that the target sensor is abnormal according to the detection result of the target sensor, each sensor is controlled to execute detection again, and the residual information obtained according to the detection result is written into the chip and covers the modified toner residual information, so that the space for storing data may be saved.
Of course, whichever of the above methods of restoring the residual information is adopted, it should be noted that, once the sensor is found to be a virtual sensor in the detection process, the error may be directly reported, and the above information restoration process is not performed.
