Safety Icons  
This section explains how to identify and understand dangers, warnings, 
cautions, and notes that are in this document. You may also see icons that 
tell you when to follow ESD procedures and when to take special 
precautions for handling optical parts. 
 
A warning alerts you of an operating procedure, practice, condition, 
or statement that must be strictly observed to avoid death or serious 
injury to the persons working on the equipment. 
 
A caution alerts you to an operating procedure, practice, condition, or 
statement that must be strictly observed to prevent equipment damage 
or destruction, or corruption or loss of data. 
 
This icon appears at the beginning of any procedure in this manual 
that could cause you to touch components (such as printed circuit 
boards) that are susceptible to damage from electrostatic discharge 
(ESD). When you see this icon, you must follow standard ESD 
guidelines to avoid damaging the equipment you are servicing. 
 
Because finger oils can impede the performance of scanner parts and 
dissolve the reflective coating of the plastic mirrors, always wear finger 
cots or non-powdered latex gloves when handling optical parts. 
 
Note: Notes either provide extra information about a topic or contain 
special instructions for handling a particular condition or set of 
circumstances.
