Product Information Each of Static Control’s 100 separate blade products has to comply with our industry-leading performance specifications. They are fully system-qualified in our Imaging Technology Laboratories, and they deliver consistent, accurate performance. We offer recovery blades, wiper blades, doctor blades and sealing blades. Worn wiper blades may cause print defects such as streaking and wear lines and are also prone to flipping. Most importantly, worn blades won't clean the residual toner, leading to toner build-up on the drum and PCR. Our OEM-style blade ensures optimum drum cleaning and blade durability.
