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
Ω) 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 , SI, 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.
