Renewing a fax

Fax may now be a fossil way of communication, but still indispensable even in this 'heyday' of internet. As a fax machine in my lab has got old and sometimes does not work fine, I am replacing it with new one, still looking for an old fashioned type with a roll of thermal paper. Many of the current models use sheets of normal paper and themal transfer ribbon/ink/toner cartridge, but I do not like it. Because, we have to take care of two or more things, the papers and the ribbon/ink/toner, to keep it right. We do not have enough time to take care of this kind of machine experted to work in a meintenance-free manner. So I prefer the one using thermal paper roll, which is the only thing we cannot run out. A pitfall of this type of paper is to set it right side. Otherwise you will see only blank pages. I did this stupid mistake yesterday. Who sent me the fax?
