Clean the scanner on a reqular basis as described below to maintain peak scanning performance.
Solution
The shading boards are the white standard boards located behind the platen rollers. A dirty shading board may alter scanned colors or cause marks on the images.
When cleaning the scanner or inside of the scanner, turn OFF the power switch and unplug the Power Cord from the outlet.
The power needs to be ON when cleaning the rollers and the shading boards. Be careful of electric shocks when working on the scanner while the power is ON.
Do not use excessive force when removing or attaching the rollers. Doing so may damage them.
Do not use spray type cleaners to clean the scanner. Precision mechanisms, such as the light source, may get wet which will cause a malfunction.
Never use paint thinner, alcohol, or other organic solvents to clean the scanner. Such solvents can damage or discolor the exterior of the scanner. They also create a risk of fire or electrical shock.
Turn ON the power.
Hold the upper unit as shown in the diagram, and open it slowly until it stops.
The pickup roller is located in the middle of the upper unit. Do not hold the protrusion on the upper unit when you open it. Doing so may deform the pickup roller or cause a feeding error.
Be sure to open the upper unit until it stops. If it is not opened all the way, the shading boards cannot come out.
Press the START button for about two seconds. The shading boards come out above the platen rollers (upper and lower).
Wipe the surface of the shading boards only with a firmly wrung cloth moistened with water.
Wipe the upper and lower shading boards.
Press the STOP button. The shading board goes back in.
Close the upper unit slowly. Be sure that the upper unit is completely closed by pushing on edges with hands until you hear a click.
Do not force the upper unit to close. Doing so may damage the scanner.
