A printer cleaning blade, also known as a wiper blade, is a crucial component in laser printers, responsible for removing excess toner from the photosensitive drum after each print cycle. This prevents toner buildup, which can lead to print defects like backgrounding or double images. The blade, typically made of a durable polymer, wipes the drum clean and directs the excess toner into a waste bin.
