A friend of mine did indeed have some very important faxes fail to come through once. Turns out a friend of his decided to play a little prank. He taped a few sheets of paper together into one big long sheet. After he faxed the first sheet, he taped it to the last…and happily watched his Mobius fax use up all of my friend's paper.

Let the offenders know how it feels to run out of paper. Get their fax numbers and 'use the Mobius Fax,' schemes Vince Nestico, who runs The Anti-Telemarketer's Source Web site (http://www.antitelemarketer.com/). "Tape about six sheets of construction paper together lengthwise, and start the fax . . . after the fax has passed through the first page, take the opposite end of your construction paper strip and flip it over once. Tape that end to the end that has already passed through, creating a continuous strip."

Next, we send them a "Mobius FAX" we got some sheets of black construction paper, taped about 10 of them together, and started feeding them through the fax. Once the start of the long sheet we had created came through, we taped it to the end.
