How to fax multiple pages at once? -

I am only able to fax 1 page at a time but I need to fax 20+ pages. Is there a way to put in the number of pages and fax number only once even if I put the pages in 1 at a time?

No. Put all the pages in the machine and dial the number. If you put them in one at a time you have to dial the number each time (or hit resend).

your best solution is using online fax services, they allow you to use broadcast faxing which means you can send several faxes all at once and all from your computer, check out http://faxfromyourcomputer.com/
