How to cancel or stop a fax (sending or receiving)

There are a number of ways to cancel a fax, whether it is being sent or received, or if you are receiving nuisance or junk fax calls from a specific fax number.

How to cancel or stop a fax that you are sending

If you are in the process of sending a fax that you want to cancel, there is typically a “cancel” or “stop” button on a fax machine. The button is typically red and often has the shape of an ‘X’ on it.

When you press the cancel button, the transmission will stop sending.

Another way to cancel the transmission is to pick up and put down any telephone handset attached to the fax machine. Unplugging the phone/fax line will also stop the transmission, and sometimes holding down the “hook” or “hook/flash” button will also interrupt the line.

The receiving fax machine will mark the transmission as “not complete.”

Any data that has already been sent will likely be printed by the receiving fax machine.

With most fax machines, the number of pages that have been scanned is not an indication of how many pages of the fax have been sent. Many fax machines have a scanner or document feeder that stores multiple pages of the fax in memory. When the fax transmission occurs, it is from the memory of the fax machine.

There is no way to cancel a fax after it has been completely sent.

If the received fax is successfully cancelled, then the sending fax machine will not receive a “successful transmission” message for the confirmation page. The receiving fax machine should also have a “transmission failure” note for the transmission.

Sometimes the fax machine will keep printing even after the cancel button has been pressed. This is normal, as the pages printed are pages in memory.

How to cancel or stop junk faxes

In many places, there is a “do not call list” such as in the United States, Canada, and the United Kingdom. As well, many countries also have legislation in place to prevent junk fax activity.
