Standard prefabricated screw fittings are supplied accessories. Although the standard configuration of each model is different, the common standard configuration parts are memory and paper feeder. 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 lacking, it will affect the use and performance of the product to a certain extent.
Optional prefabricated spiral fittings are components that, in addition to the standard configuration, enhance product functionality and improve product performance, and are purchased separately. Unlike standard configurations, the use of optional prefabricated spiral fittings does not affect the basic functioning of the product. There are many types of optional prefabricated spiral fittings. The optional products supported by different products are also different. Therefore, you should consult the product description before purchasing the optional prefabricated spiral fittings, so as not to buy them.
