Passage: I wanted to send a faxed copy of my birth certificate to my mortgage company , because I needed to apply for a home loan . I drove to the local Office Depot where they allow you to send faxes for $ 0.99 each page . I paid the worker at Office Depot the money . I went to an available fax machine that no one was using and I inputted that I needed to send out one page . I inserted the page facing down in a slot where the machine would scan it . I also put the telephone fax number of the outgoing fax I needed to send , which was the mortgage company 's fax number . I then heard a sound that meant the fax went through correctly . I looked at the screen of the fax machine to verify that there were n't any errors , and it displayed a messaging saying fax sent successfully . I then took my hard copy of my birthday certificate out of the machine . Question: When did they pick a fax machine to use? Option1: after they paid Option2: when they heard a sound
after they paid
