1. Introduction
1.1 Safety precautions
● Before using the printer, thoroughly read the following safety precautions for optimum printer use.
● 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.
● If the warning in the CAUTION category is ignored, serious results may occur depending on the
situation.
● 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.
● All the instructions set forth in this manual are important and must therefore be observed without
fail.
