1. X-ray fluorescence analyzer: It mainly checks the composition ratio of the color powder, resin, film, toner, polyester, lubricant powder, carbon, etc. to verify whether the color powder is the best ratio.

2. Laser particle size analyzer, color powder particle uniformity, size, ensuring resolution, fine particle size, powder blocking rate, fluidity, clarity, transfer rate.

3. A three-dimensional microscope with 1000 times ultra-close depth , analyzes powder particles' smoothness, uniformity, appearance quality, etc., and identifies physical and chemical powders, whether they are damp or agglomerated.

4.Capillary rheometer, analyze the fixing temperature range, deinking temperature range, fixing firmness and fixing viscosity, analyze the cause of deinking.

5. The three-dimensional measuring instrument, measures the quality and accuracy of the powder cartridge, whether there is a deviation that affects the chip alignment contact, whether the chip detector is broken, whether the rotation is bad, and the powder is affected by the powder, the powder leaks, etc.

6. Handheld colorimeter: detect color difference, color density, eliminate color difference, avoid printing color cast and individual subjective differences.
