BE SURE TO READ BEFORE USE.
Introduction
Thank you for purchasing our intelligent printer M252A.
This product is to be used by connecting it to our loadcell indicators or digital indicators through the
SI/F (two-wire serial interface). External equipment data other than our indicators can also be
printed by adding optional BCD input or RS-232C interface.
Read this manual and understand the descriptions carefully before use.
After reading the manual, always keep it handy so that it can be referred to at any time.

SAFETY PRECAUTIONS
Be sure to read for safety.
In order to have an M252A Intelligent Printer used safely, notes I would like you to surely
follow divide into and , and are indicated by the following
documents. Notes indicated here are the serious contents related safely. Please use after
understanding the contents well.
WARNING
CAUTION
WARNING
Misuse may cause the risk of death or
serious injury to persons.
CAUTION
Misuse may cause the risk of injury to
persons or damage to property.

WARNING
●For the entire system to function safely when the M252A becomes faulty or
malfunctions, provide a safety circuit outside the M252A.
●Do not modify the M252A. Doing so may cause fire or electric shocks.
●Do not install in the following environments.
- Places containing corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.
●Do not connect a commercial power source directly to the signal input/output
terminals.
●Be sure to use crimp contacts for connection to terminal blocks, and never connect
bare wires.
●Be sure to ground the protective ground terminal.
●Before performing the following, make sure that no power is applied.
- Attachment/detachment of connectors of options, etc.
- Wiring/connection of cables to the signal input/output terminals.
- Connection to the ground terminal.
●For connection to the signal input/output terminals, check the signal names and pin
assignment numbers, and then carry out wiring properly.
●Before applying power, carefully check the wiring, etc.
●Use at a proper power supply voltage.
●Do not damage the power cord. Doing so may cause fire or electric shocks.
●Do not touch any signal input/output terminal while applying power. Doing so may
cause electric shocks or malfunctions.
●In the case of smoke, an abnormal smell or strange sound, immediately turn off the
power, and disconnect the power cable.
●About the built-in lithium battery
Never disassemble, deform under pressure or throw the battery
into fire.The battery may explode, catch fire or leak.

CAUTION
●Do not install in the following environments.
- Locations exposed to direct sunlight.
- Where the temperature/humidity exceeds the range of the specifications.
- Places containing large quantities of salt or iron powder.
- Where the main body is directly affected by vibrations or shocks.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●For sensors, external inputs/outputs and options, use shielded cables.
●For turning on/off the power, be sure to keep intervals of 5 seconds or more.
●Do not open the front cover with the power on when replacing the ribbon cassette, etc.
The printer may start sudden movement, and you may injure yourself.
●Do not drop foreign objects such as screws inside the printer. If an object is dropped,
immediately turn off the power, and completely remove the foreign object before using
the printer.
●Do not touch the print head immediately after printing because the print head is hot.
●Never print without paper or a ribbon cassette. Also, do not print out of the paper width.
●Be sure to use a specified ribbon cassette. Use of an unspecified one will cause a
failure.
●After replacing the ribbon cassette, check that the ink ribbon is not slack. If slack, turn
the knob in the direction of the arrow to remove the slack before operation.
●Use paper appropriate to the specifications.
●If you dispose of the product, handle it as industrial waste.

Features of the M252A
■Dot impact mechanism
A 24-digit dot impact type printer mechanism that allows use of copying paper is loaded.
■Sophisticated statistical computing functions
In addition to grand totals and sub totals, maximum, minimum, average, standard deviation,
histograms, diagrams, etc., can be printed.
■Economical double print
Thanks to the double printing function by which data from two indicators can be printed and
added, statistical computations of a double measuring machine having two measuring heads
can be performed by one unit.
■Histograms and diagrams convenient for quality control
Variations in data can be understood visually.
■Simple setting in an interactive manner
Setting operation is simple in an interactive manner that requires input of set values according
to guidance from the M252A.
■Code classification
Print data assigned codes (within 6 characters for numerical values and katakana) can be
classified and added on a code-by-code basis (32 types at the maximum of each ch).
■Convenient free power supply
100V to 240V AC is acceptable.
■Perfect data backup
All set values and other data are stored in a nonvolatile memory and lithium-battery-backed-
up memory, respectively.
■Selectable interface
A 2-ch SI/F is equipped as standard. BCD input and RS-232C interface are optionally
available. (Only 1ch of either a BCD or RS-232C option can be connected.)
