With the exception of periodic cleaning or lamp replacement, the scanner is virtually maintenance free.  
The following sections give the procedures for basic maintenance of the scanner. 
 

 
Static electricity is a constant danger to computer systems.  The charge that can build up in your body may 
be strong enough to damage electronic components on the scanner’s printed circuit board or the computers 
interface card.  Therefore, it is important to observe basic precautions whenever handling electronic 
components for your computer.  Although areas with high humidity are much less prone to static 
electricity, it is best to always take precautions against accidental damage that can result in expensive 
repairs. 
 
The following measures should generally be enough to protect your equipment from static discharge. 
 

•  Discharge any static electricity that may be built up in your body by touching a grounded or anti-

static surface.  For example, touch some large metal object or the silver-toned expansion slot 
covers at the rear of your computer’s case.  Be sure to do this immediately before removing any 
components from their anti-static bag. 

•  When handling any electronic components, be sure to carefully avoid touching any metal part of 

the component.  Avoid touching any of the gold “fingers” that plug into the expansion slot.  It is 
best to handle system components either by their edges or by the mounting bracket which attaches 
to the slot opening in the rear of the case. 

 
Follow the above to the best of your ability.  Excessive caution is not necessary, simply take reasonable 
care. 
 

 
Regularly cleaning the object glass will ensure that dirt or smudges will not reduce the quality of your 
scanned image.  Before you clean the glass, make sure the scanner is turned off and the power cord is 
unplugged.  Clean the object glass and document cover with a soft damp cloth and a mild detergent or 
alcohol.  

 

 

Warning: 

Do not spray the cleaning fluid directly on the object glass.  Spraying the liquid directly 
on the glass may cause the liquid to penetrate the seams around the glass and 
contaminate the mirrors and lenses inside the scanner.  Please be sure you spray the 
liquid on the cleaning cloth and then wipe the glass clean.
