Points You Must Observe To Assure Product Safety
In order to assure the safe operation of this product, carefully observe the specifications as
well as the notes provided below.
Seiko Epson Corporation will not bear any responsibility for any damage or injuries arising
from use of this product that is not in accordance with the specifications and the notes
provided below.

Notes on Printer Control
1. Absolute maximum voltage
1) Printer voltage: 5.8 VDC or less
(Apply to the print solenoid, motor, trigger solenoid, for fast paper feeding and detectors.)
2. The conditions setting forth the maximum time power can be applied (and the maximum voltage that
can be applied) to electronic components such as the motor, and magnets must be observed.
If the maximum time power can be applied (or the maximum voltage that can be applied) is exceeded,
the components mentioned above could overheat and start a fire or begin to smoke.
1) Motor
The motor is DC brush motors which can be short-circuited and must there fore be protected
using a fuse that is properly matched to the power supply.
2) Print Solenoid
Under any condition (incluDdaintagSshoeftewt4aUre.croumnaway), the maximum power-on time may not
exceed 1 second.
DataShee
3) Fast Trigger Solenoid
Under any condition (including software runaway), the maximum power-on time may not
exceed 5 seconds.
4) All Detectors (Sensors and Switches)
All detectors must protect the circuitry so that current never exceeds the maximum standard.
Notes on Handling
The case must be designed so that movable parts such as gears, etc., are not exposed.
Touching moving parts could cause a laceration or other injury.
