Clean your
scanner regularly to make sure that no dust builds up on the glass
scanning surfaces. Dust can cause spots or lines in your scanned
images.
Note: The
illustrations show the ES-300W/ES-300WR, but the
instructions are the same for the ES-200.
Caution:
Do not use a hard brush, alcohol, or paint
thinner to clean the product or you may damage it. Do not use oil
or other lubricants inside the product or let water get inside
it.
