(1) When continuous printing is performed, the supply energy should be adjusted so that the head
temperature monitored through the thermistor will remain below the maximum temperature 70
℃
shown
in Table-3.
(2) Power on and off sequence must be in the following order to prevent the dot element damage;
■
Turn on - Apply the logic supply voltage (Vdd) first and the print head supply voltage (Vset) next.
■
Turn off - Switch off the print head supply voltage(Vset) first and turn off the logic supply voltage
(VDD) next.
(3) At the time of power on/off, strobe(STROBE) shall be on “Non-active Condition”.
(4) Heat elements and IC’s shall be anti-electrostatic in order to prevent the electrostatic destruction. Do not
touch the FFC terminal by naked hands.
(5) Mechanical stress or shock (including foreign particle rolling) to the surface of head substrate should be
avoided to prevent damage.
(6) When the print head operation is finished, print supply voltage. (including the charged voltage with
capacitor) should be reduced to the ground level and remained until next print head operation.
(7) Platen roller should be composed of non-conductive materials.
(8) Condensation should be avoided. If condensation occurred, do not switch on the print head power until
condensation disappeared.
(9) FFC terminal are easy to bent, please pay attention to that when the connector is plugged in or out.
At the connecting area between FFC and substrate, FFC must be handled except strongly force, like a
shock, due to protect against damage.
(10) Print quality would be degraded if paper or ink residue were stuck on the heat element area. For such a
case, please use applicator with alcohol to clean up. Do not use the sandpaper destroying the heat
elements.
(11) If printing sound, for example sticking sound, occurred, please review and adjust the paper feed
mechanism and the electrical pulse program to eliminate the sound.
(12) The change of print head flatness (warp) is minimized with temperature change in the free body of one
unit. Please pay attention to the warp created by fixing the print head to the printer unit with screws or
clamp.
(13) Please pay attention that the paper used does not include bad factor to affect the print head life.
It is recommended that a thermal paper has the following ION concentration.
.Na+ION 500ppm MAX .CI-ION 300ppm MAX .K+ION 150ppm MAX
(14) Special care should be taken to prevent rubbing thermal paper on hard cover and FFC cover by paper
guide, etc...
(15) Please take care, do not repeat bend after connecting FFC.
(16) In case of installing capacitor for noise reduction, it is recommended that capacitance is 0.1
㎌
/16V
between GND and VDD line.
(17) Installing electrolytic capacitor with high capacitance is recommended for stability on COM line.
But the capacitance is depended on current limitation of protection circuit, in case of lithium ion
battery.

http://www.woosim.com
17
(18) Please take care, all GND pins should be connected to Mother Board’s signal GND for electrical stability.
(19) Resistance of interface wire should be used it less than 0.44
Ω
/m and the length should be less than 0.5m.
