xii
Make sure that the scanner is installed on a flat, level surface and that none of its
parts extend beyond the surface top, such as a desk or table. Do not install the
scanner on unstable surfaces. Install the scanner on a level surface that is free of
vibration to prevent it from falling.
Install the scanner on a strong surface that will support the weight of the scanner and
other devices.
Do not block the ventilation ports. Blocking the ventilation ports generates heat inside
of scanner, which may result in fire or scanner failure.
Do not place heavy objects on the scanner or use the scanner's surface top to
perform other work. Improper installation might cause injuries and equipment failure.
Firmly insert the power plug as far it can go into the power outlet.
Avoid touching any scanner mechanism during scanning since this may cause
injuries.
Do not use the device immediately after moving it from a cold place into a warm room.
Condensation may occur, which might lead to scanning errors. Let the device dry
about one or two hours before you use it.
