How to determine if the small roll thermal label paper needs to be replaced?

To determine whether the small roll thermal label paper needs to be replaced, the following aspects can be considered:

1、 Appearance inspection of label paper

Color change: Observe whether the color of the label paper appears yellowing, darkening, or fading. These changes may indicate that the label paper has partially oxidized and deteriorated, and the printing effect may be affected.

Surface Texture: Touch the surface of the label paper to check if it feels sticky or if the surface becomes uneven. This may be due to moisture or adhesive failure of the label paper, which may not adhere or tear off properly during printing.

Color difference comparison: Compare the label paper to be inspected with unused label paper of the same batch to observe whether there is a significant color difference. A large color difference may indicate poor storage condition, and the quality of the label paper may have been affected.

2、 Printing effect test

Print clarity: Conduct a print test to observe if the clarity of the printed content decreases. If the printed text or image becomes blurry or difficult to recognize, it may be due to a decrease in the quality of the label paper's printing coating or damage.

Printing stability: During continuous printing, pay attention to whether there are frequent abnormal situations such as paper jams, printing misalignment, or missed printing. These phenomena may indicate that the size of the label paper is unstable or damaged and needs to be replaced.

Print persistence: Check the persistence of printed content on label paper. If the printed content fades or disappears in a short period of time, it indicates that the printing coating of the label paper is not durable and needs to be replaced with a better quality label paper.

3、 Usage time and save status

Usage time: Based on the usage record of the label paper, determine whether it is approaching or exceeding the recommended usage period. If the label paper has been used for a long time, even if there is no significant change in appearance and printing effect, it is recommended to replace it with a new label paper to avoid potential quality issues.

Storage status: Check if the label paper is stored in a dry, dark, and suitable temperature environment. If the label paper is exposed to moisture, high temperature, or direct sunlight for a long time, it may cause a decrease in its quality and require replacement with new label paper.

In summary, when determining whether small roll thermal label paper needs to be replaced, multiple aspects such as the appearance, printing effect, usage time, and storage status of the label paper should be comprehensively considered. If one or more of the above problems are found with the label paper, it is recommended to replace it with a new one in a timely manner to ensure printing quality and efficiency.
