The hard disk installed in the machine has a temporary data storage space called “Mail Box.” By saving documents in the Mail Box, you can make simple edits to files, such as combining files and deleting pages from files, from the machine. Edited documents can be converted into file formats such as PDF and TIFF that are compatible with a computer and sent to the desired destination via e-mail and the like. In addition, as files saved from a printer driver or from <Store in Mail Box> in the <Copy> function contain print settings specified when saving, such as two-sided printing, you can print the files without specifying the print settings.
