An A4 size original placed in the ADF or on the scanner glass with its long edge facing to the left is sent as an A3 size fax. Enable this to rotate the scanned image to send it at A4 size.
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.
Set the time to wait for the next original. The printer starts sending the fax after the time has passed.
