Adding text to a fax Use this feature to add one or more notes to a fax before sending it. Although you can add a note, you can't rewrite or edit the text of a fax document, nor can you delete words or insert text between words. Although the note will appear in the fax, it will not do so in the original document. Also, you can only edit the text in a Windows application, where the fax originated, not in Eclipse FAX SE. In the example below, using Microsoft Word to draft a memo, J. Austen uses the Mark Up feature (explained on the next page) to add a note before faxing it to her colleague Edward. Note, the memo she wrote in Word remains unchanged. You can add text to a fax before sending it, without changing the original document.
