Accessories can be divided into two categories: standard accessories and optional accessories.
Standard accessories are accessories that are supplied with the unit. Although the standard configuration of each model is different, common standard components include memory and paper feeders. Of course, for different models, the size of the memory and the capacity of the paper feeder are different. The standard configuration can be found by consulting the product description. If the standard configuration is missing, it will affect the use and performance of the product to some extent.
Optional accessories refer to components that can enhance product functionality and improve product performance beyond the standard configuration and require additional purchases. Unlike standard configurations, the use of optional accessories does not affect the use of the basic functions of the product. There are many types of optional accessories, and the optional products supported by different products are also different. Therefore, when selecting optional accessories, you should check the product's instructions in advance in order to avoid buying them.
