7、nformation on this product.1.2 For safety1) Precautions against heating when using thermal headThe thermal head heats up during printing or immediately after printing. The exterior case should be designed so that it does not allow the user to touch the thermal head directly. And take measures to mee

8、t the situation; for example, indicate the warnings etc so the user can be careful not to touch it. Also, design the exterior case considering the radiating of heat of thermal head so that the increase of head temperatures is minimized.2) Precautions when cleaning the headWhen the head is cleaned wi

9、th the head cleaning mechanism of this printer, indicate the warnings etc that the user should wait to clean the head until the thermal head temperatures falls fully.3) Thermal head abnormally heatingThe thermal head may run out of order (due to CPU malfunction etc) because of the mechanism of print

10、ing by giving heat to the thermal recording paper. Heating the thermal head may cause burning or fire and you may get burnt if you touch the heated thermal head. To avoid this situation be sure to adopt an abnormality detection circuit integral as hardware that breaks the current to the thermal head

11、 in abnormal situations.4) Precautions against heating when using paper feed motorA part of the paper feed motor is exposed to the frame of the printer. The paper feed motor heats up during printing or immediately after printing. The exterior case should be designed so that it does not allow the use

12、r to touch the paper feed motor directly. And take measures to meet the situation; for example, indicate the warnings etc so the user can be careful not to touch it. The paper feed motor of this printer is not equipped with the temperature detection mechanism of a thermistor etc. Thus design the ext

13、erior case considering the radiating of heat of paper feed motor so that the increase of paper feed motor temperatures is minimized.5) Paper feed motor abnormally heatingThe paper feed motor may run out of order (due to CPU malfunction etc). Heating the paper feed motor may cause burning or fire and

14、 you may get burnt if you touch the heated paper feed motor. To avoid this situation be sure to adopt an abnormality detection circuit integral as hardware that breaks the current to the paper feed motor in abnormal situations.6) Precautions when designing the exterior case around the paper feed gea

15、rThe paper feed gear is exposed so the exterior case should be designed so that it does not allow the user to touch the feed gear resulting in injuries etc.1.3 Designing precautions1) For using thermal head, see Section 4.11 Thermal Head Using Precautions.2) For designing exterior case, see Section

16、12 Exterior Case Designing Precautions3) To prevent damage to the thermal head caused by static electricity, use the tap for the earth to the thermal head and connect the earth with the frame ground.4) Minimize the wiring resistance as much as possible between power source and FFC terminal and motor

17、 connector.5) Do not apply the current when the recording paper is out or when the head is up. Doing so may affect the print quality or break the thermal head. Control the printer with the paper and head-up sensors.6) Do not allow static electricity to enter the signal terminals that is brought by t

18、ransferring the recording paper.7) Connect between the frame ground and the signal ground through the resistance of approx. 1M.8) Design the exterior case so that it can shut out foreign matter such as dust and paper chips.1.4 Handling precautions1) If paper other than the recommended recording pape

19、r is used, the print quality, the printers life etc may not be guaranteed. Also, the paper within allowable range of paper width should be used.2) Do not impose shock on the head PCB surface (heating element surface) (including no foreign matter entering).3) To prevent damage to the heating element,

20、 IC etc caused by static electricity, take care not to be charged with electricity and be sure to earth the human body.4) Do not place the printer on a surface covered with dirt and dust. Doing so will affect the printers life.5) Use a cotton swab dipped in ethanol, methanol and IPA etc and dab it l

21、ightly to remove built-up substances stuck to the heating element surface.6) Do not touch the head surface directly with the hand, tweezers etc.7) Have the head up during transporting or storing for long periods. Leaving the thermal head making contact with the platen may cause deformation of the pl

22、aten and variation of print density.8) Applying the current to the thermal head while the printer is condensing may cause a breakdown. If the printer is condensing, fully dry it to perform printing.9) When you print a barcode, the print direction against the paper feed direction should be specified
