It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Figure 1-5 The toner cartridge encryption detection device is further described.

[0024] Example 1

[0025] A toner cartridge encryption detection device, a toner cartridge slide 5 is provided with an encryption connection plate 2; includes a plurality of encryption springs 4, each of which has one end connected to the encryption connection plate 2 and the other end connected to the encryption probe 3; a detection pad 7 is arranged under at least one encryption probe 3; an encryption board 1 is provided with an encryption chip 10; the encryption board 1 is also provided with encryption board contacts 9, which are the same in number as the encryption probes 3 and are used to contact and connect with the encryption probes 3. The encryption board 1 is installed on the toner cartridge side cover 6.

[0026] The toner cartridge side cover 6 is detachably mounted on the left and / or right side of the toner cartridge assembly 8. Optionally, the toner cartridge side cover 6 is mounted on the left and / or right side of the toner cartridge assembly 8 by screws. This position installation effectively solves the problem of uneven pressure between the toner cartridge and the transfer roller and occupying a large structural space in the prior art.

[0027] The encryption board 1 is installed on the drum side cover 6 on the side of the drum, and the encryption connecting board 2, the encryption probe 3, the encryption spring 4 and the detection gasket 7 are installed in the drum slide in sequence, and the top of the encryption probe 3 is exposed on the outside.

[0028] When the toner cartridge is installed in the laser printer, the encryption probe 3 is pressed against the encryption board 1 on the toner cartridge side cover 6, the encryption chip 10 on the encryption board 1 is connected to the encryption probe 3 through the encryption board contact 9 on the encryption board 1, the encryption probe 3 is then connected to the contact on the encryption connection board 2 through the encryption spring 4, and the encryption connection board 2 is connected to the printer main control board through the connector and the wiring harness.

[0029] The utility model can detect and distinguish whether the installed toner cartridge is an original toner cartridge, and verify whether it is an original toner cartridge by detecting the encryption chip 10 on the encryption board 1 on the main control board; it can also detect separately whether the toner cartridge has been installed, and when the encryption spring 4 is compressed, one of the encryption probes 3 is separated from the detection gasket 7 to trigger the switch disconnection function, and it is determined that the toner cartridge has been installed at this time.

[0030] The utility model has a small volume and does not occupy extra space when installed in the cartridge slideway 5. The two detection states can be used simultaneously or separately. The two-in-one detection of the cartridge encryption and the cartridge installation can save the production cost of the product.

[0031] Example 2

[0032] As a new embodiment or a supplement to Embodiment 1.

[0033] This embodiment is composed of the following parts: an encryption plate 1, an encryption connection plate 2, an encryption probe 3, an encryption spring 4, a cartridge slide 5, a cartridge side cover 6, a detection gasket 7, and a cartridge assembly 8. This embodiment preferably uses 4 groups of encryption probes 3 and encryption springs 4, and other numbers of encryption probes 3 and encryption springs 4 can also be used according to actual needs.

[0034] The encryption board 1 is composed of an encryption chip 10, an encryption board contact 9, an encryption board boss 12 and a PCB board 11. The encryption board is hot-pressed and riveted on the toner cartridge side 6 by hot-melting the fixing column of the toner cartridge side cover at the position of the encryption board boss 12. The toner cartridge side cover 6 is installed on the toner cartridge assembly 8 by screws; the encryption connection board 2 is composed of a connector socket 14, an encryption connection board contact 13 and an encryption connection board PCB board 15. The encryption connection board 2, the encryption probe 3, the encryption spring 4 and the detection gasket 7 are installed on the toner cartridge slide 5 in sequence, and then the toner cartridge slide 5 is installed on the frame, and the encryption connection board is connected through the wiring harness. 3 is connected to the printer main control board; when the toner cartridge assembly 5 is installed in the printer, the encryption board contacts 9 on the encryption board 1 are in contact with the encryption probes 3 respectively, and the encryption probes 3 are connected to the encryption connection board contacts 13 on the encryption connection board 2 through the encryption springs 4, and finally connected to the main control board through the connector socket 14 and the wiring harness on the encryption connection board; the main control board determines whether the program code in the encryption chip 10 of the encryption board 1 on the toner cartridge assembly 8 is original. If it is original, the toner cartridge printer can be used normally and can record the number of printed pages. If it is not original, the toner cartridge printer cannot print normally.

[0035] Each encryption probe 3 is lifted up by the corresponding encryption spring 4, and a detection gasket 7 is installed under one of the encryption probes 3. Before leaving the factory, the detection gasket 7 can be designed and installed under any encryption probe 3; when the toner cartridge assembly 8 is not installed, the encryption probe 3 contacts the detection gasket 7. After the toner cartridge assembly 8 is installed, the encryption spring 4 is compressed, the encryption probe 3 is lifted up, and separated from the detection gasket 7. When installing the toner cartridge, each encryption probe 3 is compressed into the toner cartridge slide 5 by the encryption board 1 on the toner cartridge side cover 6, and the contact on the encryption board 1 is connected to the encryption probe 3, so that the toner cartridge chip can be tested and verified whether it is produced by the original factory. At this time, the encryption probe 3 is separated from the detection gasket 7 to trigger the switch disconnection function, so that the main control board determines that the toner cartridge has been installed at this time.

[0036] This solution can also set the printer to allow users to temporarily use non-original toner cartridges to print a few pages of documents slowly when the original toner cartridge chip cannot be detected, so as to avoid unnecessary losses for customers.

[0037] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and utility model concept of the utility model within the technical scope disclosed by the utility model. Without departing from the concept of the utility model, simple deductions and substitutions can also be made, which should be covered by the protection scope of the utility model.
