The method can obtain the actual ink amount in the ink box, and prevents the problems of ink waste, damage to a printing head due to idle printing or line break during printing. It should be understood by those skilled in the art that after receiving the command from the printer, the ink amount information may be directly fed back to the printer from one of the storage element 410 and the first chip 300. In addition, it should be understood by those skilled in the art that the storage device 410 and the first chip 300 can respond to various commands of the printer respectively, and can also cooperate with each other to respond to commands of the printer, i.e. the storage device 410 and the first chip 300 are linked with each other for information exchange with the printer.

In other embodiments, the reset switch 422 may also be an infrared sensor, sensing is performed by using infrared rays emitted by the infrared sensor, and the ink bag 200 is provided with a reflector for receiving and reflecting the infrared rays, so that the reset switch 422 can be activated by:

when the ink bag 200 is inserted into the printhead housing 100, the reflector on the ink bag 200 reflects the infrared rays emitted from the infrared sensor, thereby forming a linkage to activate the reset switch 422. Or, in the state that the ink bag 200 is pulled out, the reflector on the ink bag 200 does not reflect the infrared ray emitted by the infrared sensor, and linkage is formed, so that the reset switch 422 is activated.

In other embodiments, the reset switch 422 may also be a pressure sensor, and a protrusion capable of pressing the reset switch 422 is disposed on the surface of the ink bag 200 close to the reset switch 422 by using the self-contained contact pressure sensor of the pressure sensor, so that the reset switch 422 can be activated by:

when the ink bag 200 is inserted into the printhead housing 100, the protrusion of the ink bag 200 presses the pressure switch, which is interlocked to activate the reset switch 422. Or, in the state that the ink bag 200 is pulled out, the convex part of the ink bag 200 presses the pressure switch to disappear, and linkage is formed, so that the reset switch 422 is activated.

By way of the above examples, the reset switch 422 may be any type of reset switch 422, or may be any linkage type, which is not limited as long as it can trigger a reset command.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
