Cannot send Fax messages on Brother 420 due to full memory.

This message means the memory capacity of the unit has been exceeded. The amount of memory used depends on the amount or type of data on the documents being faxed or copied.

1. If you get an "Out of Memory" message while scanning the first page of a fax, press Stop/Exit to cancel scanning.
2. If you get an "Out of Memory" message while scanning a subsequent page, you can either press Fax Start to transmit the pages that were scanned so far or press Stop/Exit to cancel the operation.

When Fax Storage is set to On, a copy of all received faxes are stored in the memory, thus using up a % of the memory available for other functions.
The Fax Storage feature is utilized for Fax Forwarding, Fax Paging and Remote Retrieval. If you do not need these features, verify Fax Storage is set to Off by doing the following:

1. Press the Menu/Set key.
2. Press the arrow key until FAX appears on the LCD. Then, press Menu/Set.
3. Press the arrow key until REMOTE FAX OPT appears and then press Menu/Set.
4. Pressthe arrow key until FAX STORAGE and then press Menu/Set.
5. Check the setting. The display will read ON or OFF. If the setting is ON, press the arrow key until the display reads OFF.
6. Press Menu/Set.
7. If you have faxes stored in the memory, you will receive a message that reads Erase all fax? 1. Yes 2. No. If you want to erase all the faxes in the memory without printing them out, press 1 (Yes) and then press Stop/Exit.
   

Note

If you would like to reprint the saved faxes, press 2 (No), press Stop/Exit and continue to the following steps for instructions on how to print stored faxes.

If you do need the features that require Fax Storage to be On, the stored faxes will need to be erased or printed to remove them from the memory and to allow additional memory to be available. Follow these steps to print the stored faxes:

1. Press the Menu/Set key.

That should do it for clearing faxes you dont need you can also print off all the faxes in the memory and I believe that clears it.
