Barcode printer ribbon wrinkles:

Barcode printer ribbon creasing is a common problem that can be caused by a variety of reasons. Here is a detailed analysis of the problem and how to solve it:

Cause analysis

The pressure on both sides of the printer is unbalanced or too high:

This is a common cause of ribbon creases. If the pressure on both sides of the print head is uneven, the ribbon will be stretched unevenly as it passes through the print head, resulting in creases.

The carbon tape is not properly wrapped around the carbon tape frame:

Improper installation of the carbon belt can also cause it to crease during the printing process. For example, the carbon tape is not tightly wound around the carbon tape rack, or slides during the printing process.

Incorrect temperature setting:

Printing temperature is too high will also wrinkle the carbon strip. Because the high temperature will soften the carbon strip material, it is easier to deform when passing through the print head.

Ribbon and label sizes do not correspond:

If the width of the ribbon is much larger than the width of the label (for example, more than 3cm), the excess ribbon may become wrinkled during the printing process due to insufficient support.

The media did not set the paper amount correctly:

The amount of paper for the medium (such as label paper) is not set correctly, which may also cause the ribbon to mismatch with the medium during the printing process, resulting in wrinkles.

Print head component problem:

The position of the front stop of the print head part is loose or the left and right positions are too large, and the print line is not parallel to the rubber roller, which may lead to unbalanced pressure of the print head, and then cause the color band to wrinkle.

Carbon strip quality issues:

The carbon belt already has wrinkles when it leaves the factory, or wrinkles occur during use due to improper preservation.

Machine internal contamination:

The path through the carbon belt is not clean, or the baffle in front of the print head is scratched and stained, which may also affect the normal operation of the ribbon, resulting in wrinkles.

solution

Adjust print head pressure:

Use the pressure control knob or device on the print head to reduce the pressure and adjust to the pressure balance on both sides. The exact procedure may vary depending on the printer model, but usually involves pressing the pressure adjustment knob down vertically, turning it to the appropriate gear, and clamping the pressure column into the corresponding groove.

Re-install media and carbon tape correctly:

Ensure that the carbon tape is tightly wrapped around the carbon tape rack and that the media and carbon tape are properly installed according to the instructions.

Adjust the printing temperature:

By editing the "print Settings" or "bar code machine Settings" option in the software, reduce the brightness of the print (that is, reduce the printing temperature) to avoid softening and deformation of the carbon strip due to high temperature.

Replace the correct size label or ribbon:

Make sure the width of the ribbon matches the width of the label and avoid using ribbons that are too wide.

Reset the correct amount of paper for the medium:

According to the printer's instructions, reset the paper amount of the medium to ensure the matching of the medium and the ribbon during the printing process.

Clean the inside of the machine:

Regularly clean the path of the carbon strip and the baffle in front of the print head to ensure that they are clean and free of dirt.

Replace the carbon belt:

If the carbon strip itself has quality problems or has been seriously wrinkled, a new carbon strip should be replaced in time.

Through the above method, it is usually possible to solve the problem of barcode printer ribbon creasing. If the problem persists, it is recommended to contact the printer manufacturer or professional maintenance personnel for inspection and repair.
