I. Feedback on the Performance of the 668 Printer
  1. Power Restart Issue When Printing Pictures
    • Problem Description:
      When using the 668 printer, we've noticed that if you continuously print pictures with deep black tones, the printer may restart.
    • Detailed Explanation:
      When the 668 printer is handling picture printing tasks with high color concentration, especially when continuously printing pictures with deep black tones, its internal power supply mechanism will be significantly affected by the heavy load, which may lead to a restart. This kind of situation usually doesn't occur when printing shipping labels or other contents that don't require high color depth.
    • Suggestions for Customers:
      To ensure the stable operation of the printer, we don't strongly recommend using the 668 printer for picture printing, especially for pictures with a large amount of deep black tones. This printer is more suitable for printing shipping labels and other label contents with relatively low color requirements.
