Embodiment Construction

[0027] Please refer to figure 1 , figure 1 A system block diagram of an inkjet output device 10 disclosed in the present invention is shown. Many other features of the inkjet output device 10 are the same as those in the prior art and are widely known to those skilled in the art, so no detailed description is required. However, the present invention provides a method for identifying ink cartridges. The temperature sensing element (Thermal SensingElement) 22 installed on the ink cartridge (Ink Cartridge) 12 enables the inkjet output device 10 to determine whether the ink cartridge 12 is on the basis of the sensing signal 18. At the same time, different temperature sensing elements 22 can be used to cause the sensing signal 18 to fall within different signal ranges to achieve the purpose of identifying different types of ink cartridges 12 . The detailed composition and operating principle of the inkjet output device 10 will be described in detail as follows.

Abstract

The invention provides an inkjet output device, which installs different temperature sensing elements on different types of ink cartridges, and uses a detection circuit to generate a sensing signal according to the operating temperature of the print head sensed by the temperature sensing element, While making the control circuit judge the working temperature of the print head according to the sensing signal, it can also use different temperature sensing elements to make the sensing signal fall within different signal ranges to achieve the ability to identify different types of ink cartridges. Purpose.

Description

technical field [0001] The invention provides an inkjet output device, especially an inkjet output device which utilizes a temperature sensing element to identify the type of the ink cartridge. Background technique [0002] Due to the vigorous development of the computer market in recent years, the demand for computer peripheral products has also increased day by day, which has also led to the diversification of its types and the improvement of quality. Among many modern computer peripheral products, inkjet printers have always been a major output device. mainstream. Since color output printing has gradually become popular, in order to improve the output printing quality, inkjet output devices including more than two ink cartridges (Cartridge) (except inkjet printers such as fax machines, multi-function processors, etc. devices) has become an industry standard to support the possibility of combining black and various multicolor printing methods. [0003] Since multiple ink...
