out from IOT according to the general user’s instruction from the control panel. When more
than one copy of an original data is ordered, the data read from IIT are first stored into the
MFD internal HDD. Then, the stored data are read out from the internal HDD for the required
number of times so that the required number of copies can be made.
・ Print function is to decompose and print out the print data transmitted by a general user client.
・ Configuration Web Tool is to retrieve the document data scanned by MFD from Mailbox.
It also enables a system administrator to refer to and rewrite TOE setting data via Web
browser.

into Mailbox within the MFD internal HDD, according to the general user’s instruction from
the control panel.
