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 between different models, common components include memory and paper trays. Naturally, the size of the memory and the capacity of the paper tray differ for various models. The specifics of the standard configuration can be found by consulting the product manual. A lack of standard accessories can, to some extent, affect the product's usability and performance.

Optional accessories are parts that enhance product functionality and performance beyond the standard configuration, and they are purchased separately. Unlike the standard configuration, the basic functionality of the product is not affected by not using optional accessories. There is a wide variety of optional accessories available, and the supported optional products vary by product. Therefore, it is advisable to consult the product instructions before purchasing optional accessories to avoid buying something that cannot be used.
