Section 1: Understanding the RISO Drum
1.1 Composition and Function of the Drum
The RISO drum is a core component of RISO printers, responsible for transferring ink to paper. It consists of a cylindrical surface coated with a photosensitive material that selectively attracts ink particles based on exposure to light. By precisely controlling the light exposure, the drum creates the desired print image.
1.2 Color Separation and Drum Channels
RISO printers typically use multiple drums, each dedicated to a specific color. This allows for the reproduction of complex color images by layering different colors onto the paper. Switching colors involves replacing the current drum with a drum loaded with the desired ink color.
Section 2: Preparing for Color Switching

Before embarking on the color switching process, ensure you have the following materials on hand:
- New RISO drum loaded with the desired ink color
