The Xerox DC400 compatible doctor blade manufactured by TOC is a precision toner metering component developed for Xerox DocuCentre series copier systems used in high-volume office and production environments. As an essential part of the toner control assembly, the doctor blade plays a critical role in regulating toner layer thickness, maintaining clean development conditions, and ensuring stable, consistent print output.

This doctor blade is engineered to match the working structure used in Xerox DocuCentre 400 systems, ensuring accurate installation and stable contact with the developer roller. Proper blade geometry and controlled elasticity help regulate toner flow evenly, minimizing common printing issues such as background shading, uneven density, and toner leakage caused by worn or unstable blades.

TOC manufactures doctor blades using standardized factory processes and carefully selected materials to achieve consistent hardness, flexibility, and precise edge geometry. Each blade is produced under strict dimensional control to ensure balanced pressure distribution and smooth toner metering. This manufacturing consistency is essential for professional copier servicing and refurbishment operations where reliability and repeatable performance are required.

As a factory-direct manufacturer, TOC supplies Xerox-compatible copier and printer components primarily to B2B customers, including copier service providers, cartridge remanufacturers, distributors, and international importers. Our production capabilities support bulk supply, OEM-style cooperation, and long-term sourcing programs, helping partners maintain reliable inventory for widely deployed DocuCentre models.

The Xerox DC400 doctor blade is widely used in copier maintenance, component replacement, and routine servicing programs. Stable blade performance helps improve toner efficiency, reduce service callbacks, and extend the service life of toner and developer components.

TOC applies strict quality control throughout the manufacturing process, from raw material inspection to final dimensional and functional checks. Export-ready packaging and clear product identification support efficient logistics handling and smooth international distribution.

For businesses sourcing dependable Xerox DC400 compatible doctor blades for professional servicing or resale, TOC provides a factory-level solution focused on performance stability, manufacturing consistency, and scalable B2B supply.
