Printer capable of regulating ink-jet energy according to ink-jet head temperature and relative regulating method

Abstract

This invention provides a printer and its relative device able to feedback and adjusts the heating energy according to ink jet temperature. In this invention, it uses the heat sensitive resistance with negative temperature parameters to induce the ink jet temperature and connects the resistance and one capacity by one single stable trigger to realize one wave shape control circuit to generate one impulse time responding to the resistance printer energy signals. The printer provides energy to the ink jet head to heat the ink according to the energy signals of the printer to avoid the over energy to destroy the printing effect.

Description

technical field [0001] The present invention provides a printer and a related method capable of controlling inkjet energy in real time according to the temperature of the inkjet head, in particular a printer and a related method capable of simplifying the temperature feedback control mechanism by using a monostable trigger with a simple circuit structure and a thermistor. related methods. Background technique [0002] In the modern information society, inkjet printing devices such as inkjet printers have become one of the most widely used printing devices due to their low price and excellent printing quality. Information manufacturers are also actively developing more advanced inkjet printing technologies, so that the cost of inkjet printing devices can be further reduced, and the printing quality can be continuously improved. [0003] Generally speaking, inkjet printers use the nozzle holes on the inkjet head to heat ink and inkjet printing. The inkjet head is connected t...

Problems solved by technology

[0011] One of the disadvantages of the above-mentioned traditional technology is that it needs to occupy more computing resources of the printer, and the cost of the printer cannot be further reduced

As mentioned above, the traditional printer 10 needs to use the analog-to-digital converter 22 to convert the analog thermistor TRp measurement result 28A into a digital measurement result 28B to perform heat accumulation compensation, but the circuit cost of the analog-to-digital converter 22 is relatively low. High, so that the overall cost of traditional printers can not be reduced

In addition, the conventional technology needs to occupy the computing resources of the system control circuit 14 and the storage resources of the printer 10 (that is, the comparison table recorded in the storage device 15) every time the inkjet is driven to calculate the print enable signal 26A and maintain it. energy level, and the occupancy of these system resources also prevents the performance of traditional printers from being effectively improved
