| The toner in the toner cartridge is the key to imaging during the copier process, so what causes the toner to eventually form a document on the page? First, we need to understand what is called the latent image. The copier toner unit is a cylinder coated with organic material (selenium, a rare element), which is charged up front and resists light as it strikes it. And the data signal sent to control the laser emission, scanning on the toner cartridge surface light constantly changing, so that some places will be irradiated, resistance, charge disappeared, and some places are not irradiated by light, still retain the charge, the surface of the toner cartridge formed by the charge of the latent image. A toner cartridge can generally fill powder two to three times, with the increasing amount of copy (copy), its vulnerable parts such as clean scraper, drum core, charging roller, magnetic roller will inevitably wear or damage, at this time only replace damaged parts, also can achieve a good copy effect, greatly saving office costs. Toner cartridge filling powder good by professional technical personnel to operate, toner filling powder to ensure that its waste powder completely clean, non-professional most trouble often omit this step, resulting in waste powder canister full, so as to wear drum core. When photocopiers, fax machines, all-in machine prompted lack of ink or copy the effect of a blank, can first take out the toner cartridge horizontal shake a few times, its residual powder can copy dozens of pages, add powder, residual powder will also be removed, so not only a waste of resources, more pollution of the environment. Drums with semiconductor materials, suitable for working temperature around 35 ℃. The toner toner performance decreased with temperature. Long-term use of drums in high temperature environment will exacerbate the toner drum aging, and this process is irreversible. When the ambient humidity is too high, water molecules in the air density easy ionization, toner charge after the surface potential is high. That's why the copy is so dark when you make a copy on a rainy day; If a large number of continuous copying will produce "sibilate - sibilate" abnormal discharge sound. Severe copy will appear without image of the round white spot, indicating that the toner cartridge has been partially punctured. Therefore, the copier should not work for more than half an hour in hot and rainy seasons. | ||||
