  • Page 5 Read this manual carefully and be familiar with the contents when you design printers or terminals using the printer mechanism (SMP690/691). BIXOLON is not responsible for any damage or loss occurring through improper handling of printer mechanism, or use of the product in a way that is not described in this manual, or other components of your company configuring the system.
  • Page 6 SMP690/691 ※ Safety Precau tio n s Take precautions with the following items when you design terminals or other products using the printer mechanism. Include the required precautions in the user’s manual so that users can use the products such as terminals safely.
  • Page 7 SMP690/691 ※ Desig n Precau tio n s Take precautions on following items when designing products such as terminals using the printer mechanism. a) Power on sequence should be as follows. - Startup: Apply Vdd and then Vp - Shutdown: Shutdown Vp and then Vdd b) The surge voltage between Vp and GND should be less than 10V.
  • Page 8 SMP690/691 m) The door rotation system of the external case that holds the platen block should be installed while pressing down the center of the platen roller block. If it is installed by pressing down one side of the platen roller block, it may cause a printing problem or paper jamming.
  • Page 9 SMP690/691 ※ Precau tio n s in Han d lin g Incorrect handling may damage or reduce the efficiency of the printer mechanism. Take precautions with the following. * If papers that are not recommended are used - Printing quality drops due to low thermal sensitivity.
  • Page 10 SMP690/691 j) Do not apply force to FPC while connecting and disconnecting the connection terminal (printer connection terminal). It may damage FPC. k) Provide a warning to users so that they do not change the thermal paper discharge angle and do not pull the paper during printing. It may case printing defect or paper jamming.
