What is the most effective way to ensure a fax has been successfully transmitted?

Staying near the fax machine until it confirms is the most effective way to ensure that a fax has been successfully transmitted because it allows you to monitor the transmission process in real-time. Most fax machines provide an immediate response once the sending process is completed, whether it's a confirmation message that the fax has been sent successfully or an error notification if something went wrong. By being present, you can directly address any issues that may arise during the transmission, such as paper jams, connection problems, or insufficient line quality.

Additionally, this method allows for prompt follow-up action if necessary, reducing the risk of the fax not reaching its intended recipient. In scenarios where timing is critical or sensitive information is being transmitted, this proactive approach can help avoid potential delays or miscommunications.
