1. सफेद धब्बे या पिनहोल के साथ कार्बन: स्याही के समान रूप से न फैलने के कारण। छपाई करते समय ऐसे रिबन अधूरे शब्दों का कारण बन सकते हैं। अवर मोम-आधारित रिबन में पाउडर ड्रॉप होगा।
2. The ribbon is wrinkled, this is due to the problem of the tension control system during slitting. The melting temperature of the two layers of ribbons is much higher than that of the first layer, which will result in a small area on the ribbon without words when printing.
3. The winding of the ribbon is too tight or too loose during processing, so that the ribbon cannot be matched with the printer when it is running.
4. Carbon with blanks: Because the light film is not treated well, it will cause incomplete blanks.
5. The inner diameter of the paper core is quite different from that of the printer shaft: causing the ribbon to not be loaded into the printer or the shaft to take up the ribbon.
6. The temperature is too high during transportation, which will cause the ribbons to stick together.
7. The ribbon is not long enough.
