Components can be divided into two categories: standard components and optional components.

Standard accessories refer to the auxiliary parts provided with the product. Although the standard configurations vary among different models, common components include memory and paper trays. Naturally, the size of the memory and the capacity of the paper tray differ with each model. The standard configuration details can be found by consulting the product manual. A lack of standard accessories may somewhat affect the product's usage and performance.

Optional accessories are parts that enhance product functionality and performance beyond the standard configuration, and they require separate purchase. Unlike the standard configuration, the basic functionality of the product is not affected by not using optional accessories. There are many types of optional accessories, and the available options vary by product. Therefore, it is advisable to consult the product manual before purchasing optional accessories to avoid buying ones that cannot be used.
