In this embodiment, the no feedback may be, but is not limited to: the signal connection between the printer 30 and the first memory 20 is cut off so that the ink amount data cannot be fed back to the printer.
The method embodiment provided by the embodiment can be executed in a processing module of the ink box. The printer protection method according to the embodiment of the present invention will be described and explained below by taking a process module of an ink cartridge as an example.
The embodiment also provides a printer protection method, which can be applied to a printing consumable chip, wherein the printing consumable chip comprises a first memory for storing ink amount data, and the ink amount data is used for indicating the remaining ink amount of the printing consumable, wherein fig. 5 is a flowchart of the printer protection method according to the embodiment of the invention, and as shown in fig. 5, the method flow comprises:
step S502: the processing module acquires ink amount data from the first memory.
Step S504: the processing module determines whether the remaining ink amount is below a preset threshold.
Step S506: the processing module makes error feedback to an instruction of the printer to read the ink amount data from the first memory to stop the printer when judging that the remaining ink amount is lower than the preset threshold.
In the step, under the condition that the residual ink amount is judged to be lower than the preset threshold value, the processing module makes error feedback on the instruction of reading the ink amount data from the first memory by the printer so as to stop the printer, thereby realizing the mode that the printer stops working before the ink accommodating bin is replaced, solving the problem that the nozzle circuit is damaged because no ink exists around the heating resistor before the ink accommodating bin is replaced, and realizing the protection of the printer.
In step S502, the manner of acquiring the ink amount data from the first memory may be that the processing module acquires the ink amount data from the first memory after the printer updates the ink amount data stored in the first memory.
In this embodiment, by means of acquiring the ink amount data after updating the ink amount data in the memory by the processing module, it can be realized that before the printer acquires the ink amount data next time, the processing module compares the remaining ink amount corresponding to the updated ink amount data with the preset threshold value, so as to prevent the printer from directly acquiring the ink amount data and printing again when the remaining ink amount is lower than the preset threshold value, thereby causing damage to the printer.
After step S504, the method further comprises: the processing module sends the ink amount data to the printer if the remaining ink amount is determined not to be lower than the preset threshold. By this way, the normal operation of the printer can be realized.
In step S506, the processing module gives error feedback to the instruction for the printer to read the ink amount data from the first memory in many ways.
For example, in some of the embodiments, the processing module may cut off a readout signal line between the first memory and the printer in a case where the processing module determines that the remaining ink amount is below the preset threshold, so that the second memory has no feedback to the instruction of the printer to read the ink amount data from the first memory. By the mode, the printer cannot acquire the ink amount data in the first memory and performs reprinting, so that the printer is protected.
For another example, in some of the embodiments, the processing module converts the ink amount data into preset data, wherein the preset data is used to stop the printer; and taking the preset data as error feedback, and sending the error feedback to the printer. In this embodiment, the processing module converts the ink amount data into preset data and uses the preset data as error feedback when determining that the remaining ink amount is lower than the preset threshold, so that the printer sends the error feedback to the printer when reading the ink amount data next time, so as to stop the operation of the printer, thereby protecting the printer.
For another example, in some embodiments, the processing module obtains preset data, wherein the preset data is used for stopping the printer; and then the preset data is used as error feedback, and the error feedback is sent to the printer. In this example, the processing module may obtain the preset data by presetting the preset data configured in the second memory by the user, and obtaining the ink amount data from the second memory and sending the ink amount data to the printer as an error feedback when the processing module determines that the remaining ink amount is lower than the preset threshold and the printer reads the ink amount data next time, so as to stop the operation of the printer, thereby protecting the printer.
It should be noted that, in the printer protection method according to the embodiment of the present invention, reference may be made to the description related to the specific implementation of the functions of each functional module of the printing consumable chip, and details are not described herein again.
The method of the embodiments of the invention will be described and illustrated with reference to the accompanying drawings and preferred embodiments.
Fig. 6 is a flowchart of a printer protection method according to a preferred embodiment of the present invention, as shown in fig. 6, the flowchart includes:
step S601: the printer sends an instruction to read the ink amount data to the printing consumable chip to acquire first ink amount data H1.
Step S602: after receiving the instruction of reading the ink amount data by the printer, the printing consumable chip acquires the first ink amount data H1 from the first memory, sends the first ink amount data H1 to the printer, and executes the step S603; in addition, the printing consumable chip also judges whether the first ink quantity data H1 is lower than a preset threshold value, if so, the printing consumable chip enters an 'exhaustion mode'; otherwise, the printing consumable chip keeps the normal working mode.
Step S603: the printing consumable chip executes the print job after receiving the first ink amount data H1.
Step S604: the printer estimates the ink consumption Δ H of the print job based on the data such as the paper consumed by the print job and the coverage area of the printer screen.
Step S605: the printer estimates the remaining amount of ink in the ink cartridge after the execution of the print job, i.e., second ink amount data H2, based on H1 and Δ H.
Step S606: after the print job is completed, the printer sends an instruction to write ink amount data to the printing supplies chip to write the second ink amount data H2 to the first memory of the printing supplies chip.
Step S607: the printer sends an instruction for reading the ink quantity data to the printing consumable chip so as to acquire the ink quantity data stored in the first memory.
Step S608: under the condition that the printing consumable chip is in a normal working mode, after the printing consumable chip receives an instruction of reading ink quantity data, the printing consumable chip takes out the ink quantity data from the first memory and sends the ink quantity data to the printer; under the condition that the printing consumable chip is in the 'exhaustion mode', after the printing consumable chip receives an instruction of reading ink quantity data, the printing consumable chip gives error feedback to the printer.
Step S609: the printer receives the ink amount data sent by the printing consumable chip and judges whether the ink amount data is consistent with the second ink amount data H2; if the ink quantity data is consistent with the ink quantity data, the printer completes the ink quantity data reading and writing process and waits for the next printing task. Otherwise, the printer reports an error and stops working.
It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here. For example, the printer estimates the ink amount consumption amount of the print job of this time in step S604, and is not limited to after the execution of the print job in step S603, but may be before the execution of the print job. For another example, in step S602, the printing consumable chip determines whether the first ink amount data H1 is lower than a preset threshold, and if so, the printing consumable chip enters an "exhaustion mode"; otherwise, the step of maintaining the printing consumable chip in the normal operation mode may be performed between any one of the steps S602 to S608.
