When there are multiple faxes waiting to be sent to the same recipient, this groups them together to send them at once. Up to five documents (up to 100 pages in total) can be sent at one time. This helps you save on transmission costs by reducing the number of connection times.
Saves documents that failed to be sent in the printer's memory. You can resend the documents from the Job/Status.
