Delayed Batch Transmission
Before sending the delayed faxes, your MFC will help you economize
by sorting all the faxes in the memory by destination and scheduled
time. All delayed faxes that are scheduled to be sent at the same
time to the same fax number will be sent as one fax to save
transmission time.
