element itself, the application power decreases, the results can not reach a sufficient concentration. And because the current increases, the noise thermal paper print head increases, use sufficient noise countermeasures. (3) Please design a circuit can be broken to prevent damage when thermal paper resistive thermal print head is too large to cause damage. (4) from the VH, GND wiring resistance thermal paper to the respective printhead approximately 10mΩ or less, a length of less than 100 cm. To avoid interference with the signal system, we recommend that you use the power cord from the signal line design selection. (5) CLOCK (clock), LATCH (lock), DATA (signal), STOBE (strobe) of the various input signals, using the C-MOS (74HC240 level) to connect the circuit. (6) In order to prevent noise, set the maximum load voltage 15V, capacity aluminum electrolytic capacitor 33uF around between VDD-GNDL. Order (7) switching power supply is to VDD, then VH; turn off the power of the order is VH, and VDD. (When the power on / off when the strobe signal must remain closed.) Mechanical considerations (1) can not change the spool core / twisted rubber thickness required to be maintained at about 2 mm or more. (2) If the partial pressure exceeds a pre***ermined value reel, the print head life will be shortened, so the pressure to be evenly pressed all the paper width of the print head. Note the use of (1) at a high printing rate conditions of continuous printing, in order to avoid burning heat generator, ensure that the substrate temperature does not exceed a pre***ermined value. (2) In order to avoid thermal paper print head is corroded, use ethanol or IPA wipe the surface of the heating element confet
