How to solve the problem of unclear ribbon printing of tto coder printer?(1)

During the use of the tto coder printer, unclear printing may occur. We first determine whether it is the problem of the coding ribbon. If it is not the problem of the tto ribbon, we can judge that there is a certain problem with the  tto coder printer. We can eliminate the following problems, and the specific analysis is as follows:

The judgment method of tto ribbon is as follows:

1. If the whole batch of tto ribbons cannot be printed clearly by several machines, it is the problem of tto ribbons. It is necessary to replace the tto ribbons of other batches.

2. If the printing at the same position is not clear, it means that the print head is broken, and replace the print head.

3. If it is intermittent, it clearly indicates that it is a problem with the tto coder printer.

4. If this tto ribbon is used in other coding machines with good printing effect, it is necessary to replace several other rolls of tto ribbon for trial use. If the number of reels of tto ribbon is still not clear, it indicates that it is the problem of the tto coder printer.
