Components are divided into two categories: standard components and optional components.

Standard accessories refer to the auxiliary components provided with the product. Although the standard configurations vary for different models, common components include memory and paper trays. Of course, the size of the memory and the capacity of the paper tray differ for various models. The standard configuration details can be found by consulting the product manual. A lack of standard accessories can somewhat affect the product's usability and performance.

Optional accessories are parts that enhance product functionality and performance, beyond the standard configuration, and are purchased separately. Unlike the standard configuration, the use of optional accessories does not affect the basic operation of the product. There is a wide variety of optional accessories available, with different products supporting various optional items. Therefore, it is advisable to consult the product manual before purchasing optional accessories to avoid purchasing items that cannot be used.
