Can I use thermal papers (labels) in a regular printer?2024-06-04T13:03:09+00:00

Unfortunately, no. Thermal paper can only be used in printers with a thermal print head, as heat activates the thermal coating on the paper surface to produce text and images. Without heat, the printer cannot create the necessary images, and the paper might get damaged or unusable.

Do different thermal printers affect the printing results on thermal papers (labels)?2024-06-04T13:00:44+00:00

Yes, different thermal printers can affect the printing results. Factors such as print head resolution, print head temperature, print speed, and printer settings all influence print quality. Also, compatibility between the printer and thermal paper affects the outcome. Using recommended or compatible thermal paper for your specific printer model ensures the best print quality.

What is the shelf life of thermal papers (labels)?2024-06-04T12:58:34+00:00

The shelf life of thermal paper and labels depends on their quality, storage conditions, and environmental factors. Generally, Sunavin’s thermal paper can last 5 to 7 years or even longer under good storage conditions (dark, dry, and average temperature). However, exposure to high temperature, high humidity, or intense light can cause the thermal paper to fade or lose its printing capability. Therefore, avoiding these adverse conditions during use and storage is advised.

Are your thermal papers (labels) environmentally friendly?2024-06-04T12:56:57+00:00

The environmental friendliness of thermal paper depends on its components and how it’s processed. Traditional thermal paper may contain Bisphenol A (BPA), a chemical with potential environmental and health risks. To reduce environmental impact, Sunavin has introduced BPA-free thermal paper. Please confirm with our sales representative before purchasing.

How do you ship these thermal papers (labels)?2024-06-04T12:49:40+00:00

Our shipping method depends on the order quantity. For orders less than 500 pieces, we usually use a courier service. For larger quantities, we typically use air or sea freight.

Why won’t the thermal transfer ribbon stay put on my printer? And why does it keep falling off after installation?2024-06-04T09:19:33+00:00

Analysis of Issues

  • The ribbon paper core is distorted, likely due to compression.
  • The ribbon paper core has large burrs and excessive paper scraps.
  • The printer’s unwinding shaft is bent and not straight.
  • If the ribbon slips on the unwinding shaft, check if the flat spring mechanism is malfunctioning.

Troubleshooting and solutions

  • Examine the paper core for obvious deformities, such as becoming oval-shaped. If detected, return it.
  • Check the paper core for any paper scraps or burrs. Clean them thoroughly and retry. If the issue persists, it may be due to deformation, warranting a return.
  • Inspect the printer’s unwinding shaft for deformation or debris accumulation. If found, replace or clean the unwinding shaft accordingly.
  • If the flat spring needs replacement, do so. If not, consider adding one or two labels to the inner wall if the inner diameter of the paper core is too large.
What’s up with the “crackling” sound like sparks during printing?2024-04-10T07:43:52+00:00

Analysis of Issues

  • The ribbon generates excessive static electricity.

  • Ensure the printer is properly grounded.
Why do the labels move while printing but the thermal transfer ribbon doesn’t move with them?2024-04-10T07:44:14+00:00

Analysis of Issues

  • The ribbon’s back coating is coarse, and there’s an inadequate amount of back coating chemicals, resulting in considerable friction.
  • The printer applies excessive pressure.
  • The printer is configured in “thermal” mode.

Troubleshooting and solutions

  • Apply self-adhesive tape to the ribbon’s back coating and check if it peels off easily. Difficulty in removal indicates insufficient back coating.
  • Adjust the printer pressure to lessen the pressure exerted by the printer head while ensuring clear printing.
  • Switch the printer’s “Printing Preferences” back to “Thermal Transfer Mode”.
What’s causing those black ink marks on the printed labels?2024-04-10T07:44:31+00:00

Analysis of Issues

  • The ribbon isn’t fully dried.
  • The printer exerts excessive pressure.
  • The label is overly thick.
  • Backfeed occurs in the printer during printing.

Troubleshooting and Solutions

  • Spread out a portion of the ribbon on the platform and lightly press the ink layer with your hands to check for excessive stickiness.
  • Decrease the pressure applied by the printer head.
  • If the label is too thick, it will leave indentations. Adjust the printer pressure accordingly based on the label thickness.
  • Abnormal printer settings during printing cause backfeed, resulting in friction marks.

  • The fracture surface of the ribbon is damaged.
  • The printing temperature is excessively high.
  • The pressure exerted by the printer head is too high.

Troubleshooting and Solutions

  • Apply self-adhesive tape to the back coating of the ribbon and check if it easily peels off. Difficulty in removal indicates back coating imperfections.
  • Inspect the fracture surface of the ribbon for nicks or burrs, and gently pull the ribbon to test its breakage resistance.
  • Reduce the printing temperature to the lowest possible setting for sharper printing results.
  • Adjust the printer pressure to minimize pressure from the printer head while ensuring crisp print quality.
Any idea why the printed labels are missing in a pattern?2024-04-10T07:41:53+00:00

  • The printer’s rubber roller is partially damaged.
  • Regular oil stains and adhesive spills are present on the label surface.

Troubleshooting and Solutions

  • Inspect the ribbon under light to detect consistent areas lacking coating.
  • Examine the printer’s rubber roller for spots or pits of damage, and replace it if necessary (the rubber roller cannot be repaired).
  • Test with another roll of labels to determine if the issue improves.
What’s causing the printed labels to have white lines or diagonal streaks?2024-04-10T07:42:28+00:00

Analysis of Issues

  • The ribbon appears wrinkled.
  • The printer head is dirty.
  • There might be broken pins on the printer head (potentially false indication).
  • Uneven pressure on the printer head results in the ribbon tilting and wrinkling during printing.
  • The printer baffle is loose.
  • The printer transition roller is loose, causing the ribbon to wrinkle before reaching the printer head.
