How can I 'kill" an incoming fax? It should be only two pages, but the second page continues to print, so far about 40 times. I have unplugged the lines and removed the paper, but the page is apparently in the memory and every time I put paper back in, the second page begins printing over and over. This is a waste of toner/ink and paper (though I've been reinserting the printed pages to reuse them. It is also making the machine unavailable for legitimate faxes. Thank you!
