Unfortunately, there is not a fax service available for students to use at MiraCosta College. When the campuses are open, the Open Computer Labs has scanners that you can use, though, so consider whether or not scanning and emailing your scanned document is an option.
There are many free online fax services that you can use. Try googling fax free online, and you'll find many options.
Alternatively, there are Kinkos in both Oceanside and Encinitas that offer fax services for a fee.
