I have a sf-560r. When printing or copying or receiving fax, the machine prints a small line near the bottom of the paper with some numbers. The numbers change each time I print or copy or receiving fax, so I assume it prints some information. What is that? And how can I get rid of it?

The various parts that open up to allow access are monitored by a micro switch. Switch the machine off and open all the access points locate the switch and make sure it is freely working and the connections are all in place. Then come back

If you see black lines on the drum, it is very likely that the drum unit is bad. Replace the drum unit and rest the drum counter. If you wait too long, you will cause toner build up in the fuser and will cost yourself several hundred dollars to get it replaced. More in labor than parts.

Use a soft cotton or very soft paper towel and wipe the excess toner from the drun. If there are lines worn in the surface of the drum, then replace it ASAP.

Open the front of the fax machine. Then pull down the the tray that has the down arrow imprinted on it. Locate the glass strip towards the back, just behind the center roller. Use a cloth and rubbing alcohol to clean the glass and that should remove the black line.
