Problems solved by technology

According to the survey, there are hundreds of types of toner cartridges produced and matched in the world, but the interaction between the organic photoconductor drum, magnetic roller, charging roller, powder knife, cleaning blade and toner has not been fully and effectively considered, resulting in Uneven quality: the effective use ratio of toner is low, and 15g~30g of unused toner and 10g~30g of untransferred waste toner will be generated throughout the lifespan, resulting in waste and pollution; the printing quality is relatively discrete Large and unstable, especially in the middle and late stages of the toner cartridge life, because various accessories often fail due to improper coordination, the function gradually weakens, printing defects increase significantly, and cannot meet the printing needs; single-page toner consumption is more than 0.04g, Filling 350g ~ 980g toner volume, can only print 11000 ~ 19000 pages, resulting in high overall cost

Embodiment Construction

[0012] In a dust-free and static-free environment with a temperature of 20°C±4°C and a relative humidity of 35% to 60%, assemble the above accessories on the toner cartridge according to the following requirements:

[0013] 1. Apply an appropriate amount of conductive paste on the conductive end of the metal shaft of the charging roller, and apply an appropriate amount of lubricating oil on the non-conductive end; 2. Apply an appropriate amount of conductive paste on the discharge contact of the organic photoconductive drum; 3. Apply an appropriate amount of conductive paste to the conductive end of the magnetic roller Apply an appropriate amount of conductive paste to the bias contact; 4. Apply even lubricant powder within 3mm of the front edge of the cleaning blade PU, and apply 1 / 3 circle of lubricant powder on the coating surface of the organic photoconductor drum. Apply uniform lubricating powder or carbon powder within 3mm of the front edge of the PU; 5. Assemble the char...

Abstract

The invention relates to matching suitable for a toner cartridge assembly for HP 4200 series printers. The invention achieves optimal properties and matching effect of accessories after assembly by setting the ranges of geometric parameters, physical parameters, photoelectric parameters, and the like of a photoconductor drum, a magnetic roll, a charge roll, a powder delivery knife, a cleaning scraper and powdered ink, thereby prolonging the service life of a toner cartridge more than 40 percent and reducing the waste powder more than 40 percent; and in addition, the invention enhances the overall printing quality, saves one third of printing cost, reduces the pollution and saves the resources.

Background technique [0002] Compared with other models, due to the impact of printer speed and output voltage, this series of toner cartridges have great differences in coating thickness, wear resistance, electrical performance range and distance between photoconductive drum and magnetic roller. The parameter requirements ranges of other components are also different. According to the survey, there are hundreds of types of toner cartridges produced and matched in the world, but the interaction between the organic photoconductor drum, magnetic roller, charging roller, powder knife, cleaning blade and toner has not been fully and effect...
