Does the charging roller fail soon after use? How TMS conductive rubber PCR keeps printing density consistently uniform all year round, explained in one article

Many corporate administrative and operation maintenance personnel have had such distressing experiences: for the toner cartridge that has just been replaced for only a few months, the printed pages show uneven density on the left and right sides, and the middle paragraphs are faint and blurry. No matter how you adjust the development parameters, the uniform imaging effect cannot be restored, and repeated replacement of brand-new toner cannot improve the situation at all. More than 90% of the root causes of such faults lie in the improper selection of the main Primary Charge Roller (PCR).


Many cheap compatible PCRs on the market use recycled inferior conductive sponge for the outer layer, with extremely large deviation of surface resistance value. After printing only a few thousand pages, there will be a surge in partial resistance, which makes it impossible to apply electrostatic charge evenly on the surface of the photosensitive drum. After the distribution of the imaging electric field becomes uneven, the printed pages naturally show uneven density. In severe cases, there will be missing edges of the whole page image and large-area faint printing. Many users choose such inferior accessories for low price, and often need secondary replacement in less than 3 months. The long-term operation and maintenance cost is far higher than that of choosing professional consumables with reliable quality.

TMS full series of PCRs are manufactured with high-purity conductive rubber integrated vulcanization molding process. The uniformity control error of outer foam layer density is less than 3%, and the full-surface resistance value deviation is controlled within the industry-leading 5%, which can stably charge and discharge the photosensitive drum evenly throughout the whole process, ensuring that the imaging electric field always maintains a consistent state. Before the launch, all products have passed 72-hour cycle tests in extreme temperature and humidity environments, and still maintain stable conductive performance after long-term use. The overall service life is 1.8 times that of ordinary universal PCRs, which perfectly is compatible with all brands of full series laser printing devices, and outputs uniform and clear printing effects all the year round. It supports retail procurement, and can also connect with bulk OEM customization requirements. Welcome to make inquiries.
