As we usually understand the good and bad of inkjet printers, the most important criteria are stability and functionality, and among the two, stability is the most important to users. What are the main factors that affect the stability of the printer? This involves the core technology of the inkjet printer, and what does the core technology of the inkjet printer include? Since the working method of the inkjet printer is electric field deflection continuous printing, the control technology involved in this aspect can be regarded as the core technology in a broad sense, mainly including the following aspects. 1. Ink dot charging control technology, from ink line separation to ink dot, from ink dot charging to splitting to deflection and recovery, which requires a mature and stable control program; 2. Ink dot phase detection technology, more phase detection A higher resolution of phase detection can be obtained to ensure good printing results. This technology is the most important factor in determining the printing quality and speed of the inkjet printer. This also requires a mature and stable control program; 3. Ink viscosity and temperature The control technology to ensure stable ink viscosity and temperature can ensure the stability of charging and splitting, so as to achieve stable printing effect without being affected by the environment, which requires good structure and engineering fluid design; Fourth, automatic cleaning control technology, this technology It includes the automatic cleaning function of switch machine, the purpose is to ensure that the inkjet printer works normally at any time, which requires a complete control program to complete the control. In addition to the above four aspects, the core technology of the inkjet printer also includes software algorithms and nozzle manufacturing.
