Made from animal hair or fiber hair roller brush, is a large engineering drawings copy machine is more methods. Due to making brush selection scope narrow, processing waste powder assist device is more, the general small and medium-sized copiers do not use this method. To the requirements of the brush is appropriate, stiffness of the softness, and the photoconductor friction on the surface, no electrostatic inclusive of toner, waste powder at the same time also can more easily be suction drainage equipment removed from the brush.

Scraper cleaning. Scrape off the remnants of return to the waste toner cartridges. Using rubber material thickness is about 2 mm or so of scraper, according to certain Angle and photoconductor surface contact and maintain a small but uniform line pressure, more than the residual toner from photoconductor scrape on the surface. This is the way adopted by most of the copy machine. Blown off the remnants of toners due to particles of fully exposed in the air, in the process of development and transfer printing with strong electric fields, sex can will be reduced greatly, and dust and paper scraps, etc may be present, generally not repeat use and discard as waste. Discarded, sealed plastic bags, should be paid attention to in order to prevent environmental pollution.

The foam roller clean. It is more than wet copier for methods. It is made of soft foam materials, such as sponge roller, due to the bubble pore can absorb liquid, through certain extrusion can the liquid out again, so you can put the toner particles stuck in the soft roll, when necessary to use the thinner toner particles will wash away.
