Cleaning the Metal Rollers
1.
Turn on the scanner.
2.
Open the document feed tray.
3.
Pressing the OPEN knob from both sides (a), pull the front unit forward to
open it (b).
4.
Use a clean dry cloth to wipe the metal rollers ( parts in the illustration).
Press the Scan button and Stop button at the same time to rotate the metal
rollers in small increments.
CAUTION
• There are two metal rollers, one for the Front Unit and one for the
scanner. Be sure to wipe both of them. Do not spray water or
neutral detergent directly on the metal rollers. Doing so can
damage precision mechanisms, such as the light source.
Moisture on the scanner or your hands also creates the risk of
electric shock.
• Scanner power needs to be turned on when cleaning the metal
rollers. Because of this, you need to exercise extra caution when
cleaning them.
