Two identical? Still a piece and a half of content. If the two pieces are the same, there is something wrong with the equipment. Find the command device!

If it is two and a half copies, it may be because the fax paper you received is relatively small, which is different from the paper size of your machine, or the paper you sent the fax may be relatively large, and the paper you received the fax may be relatively small, but these are automatically recognized by the machine. It may look like the same piece of paper, but two copies will be produced at the same time.
