Ribbon FAQs:

1, carbon with bubbles: because the ink is not evenly coated, it will cause incomplete printing.

2, carbon belt wrinkles: due to the problem of tension control system during slitting, it will lead to no words on the area on a small piece of carbon tape.Because the melting temperature of two layers of carbon tape is much greater than the temperature of one layer

3, carbon with blank: because the light film is not treated well, it will cause incompleteness and there is a blank

4. The internal strength tolerance of the paper core is too large or too small: the printer cannot be installed or the shaft cannot be brought up with the carbon belt

5, the length of the ribbon is not enough

6, the paper core has a deviation: it will cause broken tape, and the edge cannot be printed

7.The ribbon is too tight or too loose during processing, resulting in the ribbon not being able to match with the printer when running.
