Abstract

A printing device that includes an auxiliary heater to heat a head chip and a plurality of temperature sensors to measure a temperature of the head chip. The temperature sensors include a temperature sensor installed near a nozzle nearest to the auxiliary heater and a temperature sensor installed near a nozzle farthest away from the auxiliary heater.

Description

technical field [0001] The present invention relates to a printing device that ejects ink droplets to print an image and a method of adjusting the temperature of a head chip included in the printing device. Background technique [0002] Generally, an inkjet printer includes one or more printhead chips having a plurality of nozzles and a plurality of main heaters to eject ink through the nozzles. The performance of an inkjet printer depends on the viscosity of the ink. The viscosity of the ink is higher at low temperatures and decreases as the temperature increases. Therefore, the temperature of the printhead die must be maintained at a preset level to obtain the ink viscosity required for optimal printing conditions. For this, the printing device includes an auxiliary heater for heating the head chip and a temperature sensor for measuring the temperature of the head chip. The printing device adjusts the temperature of the print head chip through the following steps: measu...
