Many people will buy CF230A Toner Cartridges for their printer, so we need know some standard to choose good quality toner. First, The charge (toner charge to mass ratio): printer toner and carrier saturated friction with the power. The charge to mass ratio, expressed in units of kg. Generally its nominal value by the toner manufacturers, the limit deviation of ± 30%. After matching with carrier, the charge amount should match the requirement of developer. The nominal value of the determination of the current practice is to test the OEM model, but because of the limitations of the model, and test the choice of carrier is often difficult to determine, and then it is difficult to accurately determine the range of charge to meet the requirements of the use of only can sum up a reference range. 


Photocopies quality: including image density, bottom ash, resolution, level and fastness and so on. The standard version used include integrated board, blackboard, whiteboard, color plate, magnification board, network cable and density unevenness board, stencil, photoreceptor surface defect board. Commonly used for the first four. In general, the image density take the minimum value, ≧ 1.00, and the end of the gray take the maximum value ≦ 0.02, resolution ≧ 3.6L / mm, level ≧ 4, fixing fastness (after rubbing copy image image density reduction rate) ≦ 10% at 15 ° C and ≦ 20% at ≦ 15 ° C. In the case of imperfect physical indicators, the adoption of the toner by the quality of the copy as the basis for the determination of the most *, but also the most commonly used.


Loose density: refers to the loose state, the mass per unit volume of the toner that loose bulk density. Generally prescribed by the manufacturer nominal value, the limit deviation of ± 10%. The size of the indicator deviation from another point of view of toner particle size distribution.


Liquidity: refers to the conditions under the toner particles can be dispersed between the degree. Expressed as a percentage by weight (%) of toner passing through the shaker. Generally prescribed by the manufacturer nominal value, the limit deviation of ± 20%. 8, the caking temperature: in the control temperature, after a specified period of time, whether the toner caking evaluation. National standard must be at 45 ℃, moisturizing 24 hours without caking.
