Exciter response mimic circuit and exciter response simulation method applied to printer

Abstract

The invention discloses an exciter response mimic circuit and an exciter response simulation method applied to a printer. The positive and negative polar circuit of a prior exciter response mimic circuit comprises an insulated gate field effect transistor. According to the invention, an electrical potential control module is added into the prior exciter response mimic circuit to provide a reference potential for the positive and negative polar circuit in the exciter response mimic circuit, namely, the voltage similar to the exciter signal attached to the two ends of the exciter response mimiccircuit of the ink jet printer is taken as the reference potential. In this way, the exciter response mimic circuit applied to the printer can be matched with the exciter response of the ink jet printer based on the improvement of the positive and negative polar circuit specification.

Description

technical field [0001] The invention relates to the field of printers, in particular to an excitation-response analog circuit applied to a printer. Background technique [0002] The control part of the inkjet printer is mainly composed of the control chip and the inkjet printer, such as figure 1 As shown, the control chip is generally bound to the ink cartridge, and its role is to control the matching of the ink cartridge and the inkjet printer and the provision of printing information during the subsequent printing process. In the control chip, initial information such as the ink cartridge model, color, and total amount of ink is recorded. And printing information such as the printing date obtained in the subsequent printing process, the remaining amount of ink in the ink cartridge, etc. Inkjet printers store initial information such as the model and color of preset ink cartridges. [0003] The control part of the inkjet printer is mainly composed of the control chip an...

AI Technical Summary

Problems solved by technology

[0010] There are disadvantages in the judgment of whether the remaining amount of ink in the ink cartridge is full: first, the cost of the cavity material used in the piezoelectric ceramic module and the manufacturing involved The cost is high; second, the cavity used by the piezoelectric ceramic should be set in the ink cartridge, which has poor sealing performance, and the ink in the ink cartridge is easy to leak; third, the cavity used by the piezoelectric ceramic Long-term immersion in ink, easy to corrode

However, if the excitation signals added to both ends of the circuit by the inkjet printer are high-level signals, such as the signals added to the two ends are respectively 4 volts and 40 volts, then the positive and negative polarity circuits with the reference potential being GND It is not possible to make circuits with different impedances and time constants that meet the requirements of inkjet printers

Therefore, the compatibility of current stimulus-response analog circuits is relatively poor, and the applicable types of inkjet printers are limited.
