SMP6200II
※Safety Precautions
Take care with the following items when designing products such as terminals using the
printer mechanism, and include precautions required for user’s manual so that users of the
products such as terminals can use the products safely.
a) Precautions when cutting thermal paper
Before cutting thermal paper, check whether thermal paper supply is in stop state.
Paper powder can be generated due to the operation of automatic cutter. As the paper
powder could cause problems with electric circuits, design the system so that paper
powder does not pile up over the control device or power supply device.
b) Precautions with cutter blade
Thermal paper can be easily installed by isolating the platen roller block from the printer
main body with this printer mechanism. The fixed cutter blade will be exposed if the
platen roller block is open. In order to prevent injury to users by touching the blade
while cutter is in operation or replacing the thermal paper, design the structure with a
cover on outer case or attach a warning label to warn the users for safe operation.
c) Precautions with portable blade drive
Set the control so the motor does not operate when platen roller block is open. And
design the paper exit so that users are not injured by touching the cutter while the
cutter is in operation.
d) Precautions for preventing overheating of thermal head
When the thermal device of thermal head remains activated continuously due to a
malfunction, the overheating of the thermal head may cause a fire. Design the system
so that the thermal head does not malfunction even under abnormal conditions.
e) Precautions of temperature rise of thermal head
The temperature of the thermal head and peripheral devices is very high during printing.
Design the system so that users do not get a burn injury by touching the thermal head.
Attach a warning label so that users use the product safely.
When cleaning the thermal head, recommend cleaning work after the thermal head has
cooled down. Leave enough space between the thermal head and outer case when
designing the outer case for faster cooling of the thermal head.

Rev. 1.00 - 7 -
SMP6200II
f) Precaution about temperature rise of the motor
The temperature of step motor and the peripheral device is very high during or right after
printing. Design the outer case so that users do not get a burn injury by touching the
motor. Attach a warning label so that users can use the product safely. Leave enough
space between the motor and outer case when designing the outer case for cooling the
motor.
g) Precautions on sharp edges of the printer mechanism
The printer mechanism has many sharp corners and rough surface on the metal parts.
Design the outer case so that users do not get injured by touching the sharp edges,
and attach a label for the safety of users.
h) Precautions when driving the motor
Hair can be rolled into the platen roller and gears when they are closed.
Design the control so that the printer driver motor does not operate when the outer
case and platen roller block are open. Also, design the outer case so that external
objects do not contact the platen roller and gears, so preventing objects from jamming.
Attach a warning label so that users can use the device safely.

Rev. 1.00 - 8 -
SMP6200II
※Design Precautions
Take precautions with the following items when designing products such as terminals
using the printer mechanism.
a) The sequence of applying power is as follows.
- Startup: Apply Vdd and then apply Vp
- Shutdown: Cut off Vp and cut off Vdd
b) Surge voltage between Vp and GND must be lower than 10 V.
c) Connect 0.1 uF capacitor between Vdd and GND near to the connector to prevent noise.
d) Connect the smallest possible wire resistance (less than 50m) between the power
supply device (Vp and GND) and the printer mechanism (terminal connection). Keep
the distance from the signal wire to reduce electrical interference.
e) Cut Vp voltage when not printing to protect the thermal head from electrolytic corrosion.
Design the product so that the GND signal of the thermal head and frame ground of the
mechanism maintain the same electric potential.
f) Use C-MOS IC for CLK,/LAT , DI,/STB signals of the thermal head.
g) Do not use /STB terminal while turning on or off the power or when the printer is not
printing.
h) Always monitor the platen roller block detection switch and the output of the paper
detection sensor. Never activate the thermal head when platen roller block is open and
there is no paper. Activating the thermal head incorrectly will reduce the life of thermal
head and platen roller or damage them.
i) Always monitor the platen roller block detection switch and the output of the paper
detection sensor. If the platen roller is open without thermal paper, never try to activate
the cutter driver motor. Activating the cutter driver motor incorrectly will reduce the life
of the cutter.
j) Temporary pause time between thermal head activation for the same thermal device
must be longer than 0.1 msec. Precautions must be taken when using 1-split printing or
period of thermal activation time becomes longer. The thermal head might be damaged
if it is activated for a long time without pause.
k) Applying excessive energy to the thermal head may overheat or damage the device.
l) Noise and vibration during printing may differ depending on the pulse speed of the motor.
Check performance by actually using the device.
m) Paper feeding force may decrease depending on the pulse speed of the motor. Check
performance by actually using the device.

Rev. 1.00 - 9 -
SMP6200II
n) In order to prevent degradation of printing quality due to reverse rotation of the paper
drive system, install/remove the platen roller block or feed the thermal paper by more
than 20 steps during initialization after cutting using the cutter.
o) If the printer mechanical device is not used for a long time after cutting the thermal
paper, the paper may jam. In order to prevent this situation, feed the paper up or print
by more than 2 mm after cutting.
p) Do not feed the thermal paper backwards. If the thermal paper falls off from the
thermal head or platen roller, the printer mechanical device may not able to feed paper
anymore or it may be jammed.
q) Do not move partially cut paper forwards or backwards. The paper feeding system may
be damaged.
r) Continuous printing may cause problems to the printer mechanism because of
accumulated heat in the step motor. Therefore, when there is a need to print for longer
than few minutes, stop the printing in the middle and restart printing after the step has
sufficiently cooled down. Check performance by actually using the device.
s) Door pivot system in the outer case that holds platen roller block must be installed by
pressing the center of platen roller block. If only one end of the platen roller block is
pressed and installed, it might cause a problem such as printing defects, paper jam, cut
failure, or damage to the cutter blade. Check performance by actually using the device.
Mark the instruction to install platen roller block by pressing the center.
t) If the main body with the moving cutter blade and platen roller block with the fixed cutter
blade are not positioned correctly, it might cause printing defects, paper jam, or cutting
failure. Therefore special care must be taken to position the outer case correctly when
installing it.
u) Provide sufficient space so that the lever can be removed easily with the fingers when
designing the outer case.
v) Chattering might occur at the mechanical operating contact in auto cutter switch.
Therefore, you must configure hardware chattering protection circuit or apply software
chattering compensation program. (Max 10 ms)
w) Printing quality cannot be guaranteed if thermal paper other than specified paper is
used, and it may reduce the life of the thermal head.
x) The detection range of the paper detection sensor changes depending on the input and
output resistance value. Refer to the paper sensor detection sample external circuits in
7-1-3. Check performance by actually using the device.
y) When you turn on the power for the first time after installing the product or when you
separate the platen roller block and close it, be sure to move the paper feed motor
forward 4~8 steps. Otherwise, the first line will overlap when printing. Check
performance while actually using the device.

※ Handling Precautions
Incorrect handling of the printer mechanism will reduce the efficiency and damage the
system. Precaution must be taken with the following.
* When paper other than specified thermal paper is used.
- Printing quality may drop due to low thermal sensitivity.
- The thermal head will be worn out quickly due to rough surface of the thermal paper.
- Printer might be jammed as the thermal layer of the thermal paper might stick to the
thermal head, which may generate noise as well.
- Maintainability of the thermal paper is lower so that color of the printed matter changes.
- Electrolytic corrosion may occur due to poor quality paper.
- Cutter may malfunction due to uneven thickness of thermal paper. (Uneven mechanical
strength and paper density.)
a) When the printer mechanism is left unused for long time
Printing quality may drop due to the deformation of platen roller block. In this case, feed
the thermal paper for a short period to correct the deformation of the roller. Paper
feeding may become difficult when the thermal head touches with the roller without
paper for long time. If this occurs, take out the platen roller and install the paper again
before using it.
b) Do not clean the coating of the cutter (moving cutter blade and fixed cutter blade) with
oil. The performance of the cutter may drop.
* Do not disassemble the platen roller block during printing or cutting. It might cause
damage to the mechanical devices of the printer.
c) The reduction gear may obstruct the installation the platen roller block. In this case,
separate the platen roller and install it again.
d) Never pull out the thermal paper while installing platen roller block. It might damage the
mechanical device of the printer.
e) Do not apply force to the platen roller block during printing or cutting. It might degrade
the printing quality and paper cutting may not work.
f) Wear antistatic clothes while handling the printer mechanism, and touch the metal
pieces before starting work to discharge the static electricity built up on the body in
order to prevent damage to the thermal head by static electricity. Take extreme care
with the thermal device and connection terminal of the thermal head.
g) Do not scratch or tap the thermal head with a sharp or heavy object. It might damage
the thermal head.

Rev. 1.00 - 11 -
SMP6200II
h) When printing at high speed in an environment of low temperature or high humidity,
water drops might form on the printer mechanism due to steam generated by the
thermal paper and the thermal paper might be damaged. Do not apply power until the
water drops are completely dried out.
i) After turning off the power to the printer mechanism, do not connect or separate the
printer mechanism connection terminal (printer connection terminal).
j) Do not apply force to FPC while connecting or separating the connection terminal
(printer connection terminal). FPC might be damaged.
k) Provide warning instructions so that users do not change the thermal paper exit angle or
pull out the thermal paper during printing or cutting. It might cause a problem such as
printing defects, paper jam, or cutting failure.
l) Provide warning instructions to users to carry out printing and cutting after removing the
completely cut thermal paper. If the printing or cutting continues without removing the
cut paper, it might cause a problem such as a paper jam or to the cutting paper
depending on the mounting position.
m) When replacing the thermal paper due to damage to the thermal paper or printing
defects, provide warning instructions to users not to touch the thermal head or sensor.
n) Do not use a paper roll with the glued or folded tip. When using this type of paper,
replace with new paper before the tip of the paper roll appears.
o) Never unscrew the screws holding the corresponding parts of the printer mechanism.
Unscrewing them may degrade the performance of the printer mechanism and the
cutter.
p) The printer mechanism is not waterproof and is susceptible to water drops. Do not let it
touch the water and do not operate with wet hands. It might damage the printer
mechanism or cause a fire.
q) The printer mechanism is susceptible to dust. Do not use the printer mechanism in a
dusty place. It might damage the thermal head or paper drive system.

5. Thermal Printer Head
Thermal head is configured with a thermal device and thermal head drive that drives and
controls the thermal device. Data input from the DI terminal is “High” for printing and “Low”
for not printing. Data from DI terminals are transferred to the shift registers at the rising
edge of the CLK.
After transferring one line of data, the data is stored to the latch register by making the
/LAT signal “Low”. Depending on the stored printing data, the thermal device is activated
by making /STB signal “Low”.
Split printing with three block and 144 dots each can be supported. Split printing can
reduce the peak current.
