1. WB structure: The WB is divided into two types, one is a sticking type blade, and the other is a filling type blade, which is composed of a metal frame and rubber.
2. Working principle: The WB removes the residual carbon on the surface of the photosensitive drum after transfer.
3.Note:The WB cannot be pressed against each other and are prone to deformation;If the scraping knife is stored for too long, it will cause the rubber to become yellow and aging, and it will not be cleaned;
The wiper blade is not coated with lubricating powder during use, which will damage the drum core and cause the wiper blade to flip.
