Problem In our office we have a sharp FO-DC600 fax machine and someone was sending us a fax that was nothing but blank paper and we tried to stop it and now it is stuck in our memory. we cant figure out how to erase the received memory so we can use the machine again

Turn the machine off, then hold the STart?enter and Stop button while turning it back on. Just follow the message on the display.

Usually, you can just leave the thing unplugged- from the power supply- for a while and clear its memory. There may also be a reset button on the machine, look for it near where the ports/connectors are, and hold it down- most devices will flash a light or beep if the reset is done properly.
