Faxing begins.
NOTE
If an error occurs in the machine while sending a fax, send the document once more from the fax driver. The fax
job sent from the fax driver for which an error occurred will be erased regardless of whether [Redial When Error
Occurs] is turned [On] or [Off] at the machine.
You cannot access or edit the address book if you do not have access permission to the destination folder of the
address book. If this is the case, log on as user having access permission to the folder, or click [Specify a Folder]
in the [Edit Address Book] tab, and specify a folder, such as the [My Documents] folder, that you have write
permission for as the destination folder of the address book. For details, view the online help. (See "Viewing the
Online Help (PC Fax).")
The number of destinations that you can send to at one time depends on the conditions under which the cover
sheet has been attached. For details, view the online help. (See "Viewing the Online Help (PC Fax).")
The display may differ according to the operating system and system environment.
