● Before using the printer, thoroughly read the following safety precautions for optimum printer use. 
● All the instructions set forth in this manual are important and must therefore be observed without 
fail. 
●  After the manual  has been  read, it must be  stored  in such  a location that  all  printer  operation 
personnel can refer to it at all times. 
 
 
 
 
● You should observe the precautions set forth below in order to use the product properly and avoid 
endangering  or  causing  damage  to  you  or  other  persons.    For  the  purpose  of  clarifying  the 
severity of injury or damage and likelihood of occurrence, the precautions are classified into two 
categories, WARNING and CAUTION, which both describe the hazardous situations that may 
arise if you ignore the precautions and perform an incorrect handling or operating procedure.   
The  precautions in  these two  categories are  both  important  and must  therefore be  observed 
without fail. 
 
WARNING is used to indicate the presence of a hazard which may 
cause  severe  personal  injury  or  death  if  the  warning  against 
performing an incorrect handling procedure is ignored. 
CAUTION is used to indicate the presence of a hazard which may 
cause  personal  injury  or  property  damage  if  the  warning  against 
performing an incorrect handling procedure is ignored. 
The  △  symbols are used to indicate precautions (including those related to potential 
warnings) to be observed.    Detailed information is furnished by a picture within the 
symbol outline (a shock hazard is indicated by the example shown at left). 
The ○ symbols are used to describe prohibited actions.    The details of a prohibited 
action are given by a picture within or near the symbol outline (the example shown at 
left dictates that you must keep flames away). 
The  ●  symbols  are  used  to  describe  required  actions.    Detailed  instructions  are 
given by a picture within the symbol outline (the example shown at left dictates that a 
ground connection must be made). 
Before starting the maintenance and inspection work of this printer, thoroughly read 
and understand the “safety precautions”.     
When explaining the product to customers at the time of the installation, fully explain
