FAQ White Thermal Barcode Paper

Blurry or Faint Print

  Causes:

• The printer temperature setting is too low.

• The thermal print head is worn out.

• Poor-quality labels are being used.

• Dust or residue on the print head.

  Solutions:

• Increase the printer's print density or temperature settings.

• Clean the print head with an alcohol wipe.

• Replace the worn print head.

• Use high-quality thermal labels.

Labels Turning Black Prematurely

  Causes:

• Exposure to high temperatures, sunlight, or UV light.

• Poor storage conditions (high temperature or humidity).

• Chemicals or oil on the labels.

  Solutions:

• Store labels in a cool, dry place, away from direct sunlight.

• Keep labels in their original packaging until ready to use.

• Avoid touching labels with greasy or dirty hands.

Printer Fails to Recognize Labels

  Causes:

• Incorrect printer settings for label size.

• Sensors are not detecting the labels properly.

• Labels are not correctly loaded into the printer.

  Solutions:

• Check the printer settings to ensure they are set for 4x6-inch labels.

• Clean the label sensors to remove dust or debris.

• Reload the labels correctly to ensure smooth passage through the printer.

Paper Jams with Labels

  Causes:

• Labels are not properly aligned.

• Printer rollers are dirty or sticky.

• Damaged or defective label roll.

  Solutions:

• Ensure labels are correctly loaded and aligned in the printer.

• Clean the printer rollers with a lint-free cloth and alcohol.

• Replace the current label roll if it is damaged or defective.

Barcode Labels Not Scanning Properly

  Causes:

• Low print density or resolution settings.

• Labels are wrinkled or damaged.

• Insufficient contrast between the barcode and background.

  Solutions:

• Increase the print density settings to achieve clearer barcode printing.

• Ensure labels are flat and wrinkle-free before printing.

• Use higher resolution labels (e.g., 300 DPI for detailed barcodes).

Printer Prints Blank Labels

  Causes:

• Incorrect thermal labels are being used (not direct thermal).

• Print head needs cleaning or replacement.

• Incorrect printer settings.

  Solutions:

• Ensure you are using direct thermal labels, not thermal transfer labels.

• Clean the print head with an alcohol wipe.

• Check printer settings to ensure print density and speed are optimized.

Labels Lack Adhesion or Fall Off

  Causes:

• Weak adhesive on the labels.

• Surfaces are damp or dusty.

• Labels are applied to rough or textured surfaces.

  Solutions:

• Use high-quality labels with strong adhesive on the back.

• Ensure surfaces are dry and clean before applying labels.

• Press the labels firmly to ensure proper adhesion.
