Problems solved by technology

[0002] With the continuous development of medical technology, medical image printers have become an indispensable instrument for hospitals. At present, the medical image printers that appear on the market generally do not preheat or have preheating when printing, but the temperature control is not good. Well, so that the printed picture has a large color difference, or the warm-up time is too long, when the warm-up time is too long, the life of the print head will be greatly shortened, so a temperature control method for an image printer is needed to ensure Printed picture quality without shortening the life of the print head

Abstract

The invention discloses a temperature control system and method of an image printer. The temperature control system comprises a microprocessor chip, a FPGA chip, a thermal printing head, a heating device and a temperature measuring device, wherein the heating device and the temperature measuring device are arranged on the thermal printing head; the output end of the microprocessor chip is connected with the thermal printing head through the FPGA chip, so that a heating control signal can be output to the heating device on the thermal printing head; the temperature measuring device on the thermal printing head can measure the temperature of the thermal printing head in real time and output a signal to the microprocessor chip. According to the temperature control system and method of the image printer, the preheating time of the image printer can be effectively controlled, and meanwhile the service life of the printing head can be prolonged.

Description

Technical field [0001] The invention specifically relates to a temperature control system and method for an image printer. Background technique [0002] With the continuous development of medical technology, medical image printers have become an indispensable instrument in hospitals. At present, medical image printers appearing on the market generally do not perform preheating or preheating during printing, but the temperature control is not Good, so that the printed pictures have a large color difference, or the warm-up time is too long. When the warm-up time is too long, the life of the print head will be greatly shortened. Therefore, a temperature control method for the image printer is needed to ensure The quality of the printed image will not shorten the life of the print head. [0003] The working principle of a thermal printer is: the print head (thermal head assembly) installed with a semiconductor heating element heats and contacts the thermal printing paper and prints th...
