ATP-48 SLN(4.8V) Product Specification
3.6 Precautions at use 3.6.1 Electrical a) The temperature of there mister shall not exceed the specified limit when continuous printing is performed at high printing density. b) Circuit must be designed so that VH is set to “ OFF” (GND level) in stand-by mode in over to avoid damages to the thermal print head due to ion or noise. c) In case the number of simultaneous printable dots exceeds specified values, applied to power per heater element will be reduced by power loss of wires within a head. In such cases, sufficient optical density may not be attain. Also, because noise from thermal print head increases due to larger current, sufficient countermeasure against noise, like using twisted wire etc, shall be taken. d) This TPH does not install a capacitor on it. Thus a printer system should be designed to avoid a surge voltage. 3.6.2 Mechanical a) Platen shaft shall be designed with enough rigidity so that it won’ t warp. Rubber thickness is recommended to be more than 2mm. b) Thermal paper on the heater line shall be cleaned with Ethanol or Isopropyl Alcohol. c) Heater element surface shall not be touched with bare hands. d) Thermal paper (thermal transfer ribbon)shall be free from Na+ Cl- contamination and shall be confirmed long term reliability prior to volume use. e) There shall be no condensation on heater element surface. f) When partial pressure onto platen exceeds standard value, durability against abrasion will be reduce. In order to avoid it, structure of a machine shall be designed to have suitable pressure in accordance with paper width. g) Continuous thermal paper should be used for this thermal print head. h) It is necessary for you to pay enough attention to handling to avoid having he force at the connection area between substrate and FPC. In case of having the force, connection will be broken. 3.6.3 Recommendable circuit conditions a) GND of VDD and VH should be connected together at power supply side. b) Wiring resistance should be less than 10mΩ between thermal print head and VH, GD. Wiring length should be less than 10cm. Wires are recommendable to be twisted and kept away from signal route in order to minimize electro-magnetic interference. c) Interface device to drive the print head is recommended to be 74HC240 or equivalent (C-MOS only) d) IN order to avoid noise, all electrolytic capacitor (voltage rating :15V, capacitor: 33μ F) shall be installed between VDD and GND. e) At switching ON/OFF, STROBE shall be set “ disable” by using power-on-reset circuit of CPU, or at the time of switching “ ON” sequence must be in order of VDD first and then VH. Switching “ OFF” requires the sequence reverse order. (VH first). Revision Ver 1.0 January 9 , 2008
