Windows 10 comes with built-in fax software, Windows Fax and Scan, allowing for quick and easy fax sending from your computer. For this to work, a phone line and a fax modem are needed.
Step 1 Make sure that you have the correct equipment.
Step 2 Connect your phone line to your computer.
Step 3 Open Windows Fax and Scan. ( Start --> Settings --> Devices --> Printers & Scanners --> Fax )
Step 4 Click Connect to a fax modem if prompted. Clicking it will connect your computer to your fax modem and open the "New Fax" window. Notice - You may have to confirm this decision or click OK before proceeding.
Step 5 Enter your recipient's fax number. Type the number for the fax machine to which you're sending your fax into the "To" text box near the top of the window.
Step 6 Add a subject. In the "Subject" text box, type in whatever you want your fax's subject to be.
Step 7 Create your fax. Type your fax's text into the main window.
You can add an existing file (e.g., a photo or a document) to the fax by clicking the Attachment at the top of the window, selecting the proper file, and clicking OK.
Step 8 Click Send. It's in the upper-left corner of the "New Fax" window. Doing so will prompt your fax to send to the fax machine listed in the "To" section.
