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.
Printer Control Precautions
1. Absolute Maximum voltage
1) Printer driver voltage: DC 5 V
(Apply to the print solenoid, and motor.)
2) Detector input voltage: DC 20 V
(Apply to the reset sensor.)
2. When designing drive circuitry for solenoids, motors, magnets, and other electrical parts, always
provide for proper energizing time limit control and include overcurrent protection.
Otherwise, the components mentioned above could overheat and start a fire or begin to smoke.
1) Motor
The motor is a DC brush motor that can be short-circuited and must therefore be protected
using a fuse that is properly matched to the power supply.
2) Print solenoid
The energizing time must never exceed 1 second.
3) Reset sensor
The input voltage must not exceed the maximum rating of the sensor.
Usage Precautions
• Because the print head can become very hot, it must not be exposed in such a way that it can be
touched.
Touching the print head could cause burns.
• 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.

Summary
1. Application
This specification is applied to the M-150II.
2. Features
M-150II is the mechanical dot printer, whose Print Head consists of 4 Print Solenoids laying
horizontally and moves for 24 dots horizontally. Print Head which moves horizontally prints
unidirectionally as each Print Solenoid of it is energized in order.
When Print Head return, paper is fed for 1 pitch automatically. By repetition of this dot line printing
and paper feed desired Print Format can be obtained.
It is characterized by the following features:
1. Clear dot printing
2. Super thin thickness (12.8 mm), Small-side and Light weight (60 g)
3. Possible to copy (original 1 sheet + 1 copy sheet)
4. Ni-Cd Battery Drive
5. Low price
3. Designer’s Guide, Developer’s Manual
Refer to the separate “M-150II Designer’s Guide” and “M-150II/190/190II Developer’s Guide” together
with this specification.
4. Explanation of voltage indication
This specification identifies a usable voltage as “terminal voltage” (voltage between terminals on the
printer’s PCB). To set up the power supply voltage, consider the power supply voltage loss caused
by energizing the solenoids and the voltage drop from driver and circuit lines so that the printer can
operate within the specified voltage range.
