I learned the hard way with this machine that it's the cheap man who pays twice. I bought this fax based on price thinking one fax is as good as the next. Not so. In my opinion this is not a machine for business use because it can't be trusted to send more than 2 or 3 pages at a time. The automatic document feeder, which I've learned is really what distinguishes a home fax from a business one, is incapable of separating a stack of papers and just sends them through the machine in a jumble. The problem is that unless you've counted the pages, you'll get a report saying the fax went through just fine, when in fact it sent half of what you thought went through. Unless you stand there and watch the pages go through, you won't realize that it didn't sent the critical 30 page fax you wanted it to, but 24 of them. I'm going to buy a new machine based on the rating of the adf from this point on and hope I don't have a problem returning this one to Amazon
