Other Input Devices
If there are other input devices on the PC, you should clean them periodically as well.
How frequently you do this depends on the device and how often it is used. Here are
some cleaning hints for several of the more common input devices:
Scanner The biggest issue with a flat-bed scanner is its inside glass surface.
Use either a nonammonia glass cleaner and a lint-free cloth or the Scotch-Brite
HPEC for electronics.
Digitizing tablet Unless the digitizing surface (see Figure 22-7) is a rubber-
like material, you can clean it with a general-purpose cleaner and a damp
lint-free cloth. Take care not to get the unit too wet and dry it completely.
Digital camera Use a lens cleaner solution that you would use for eyeglasses
and a soft lint-free cloth to clean the lens. Use either isopropyl alcohol or a
general-purpose cleaner to clean the exterior of the camera. Avoid getting
the unit very wet.
Microphone Use the same procedure as for the digitizing tablet. Be
very careful not to get water or alcohol in the openings and down inside
the microphone.Chapter 22: PC Care and Maintenance^579
