4. Usage Instructions
4.1. Loading the Paper Roll
- Open the paper cover of your thermal printer according to its specific instructions.
- Remove any remaining paper core or old roll.
- Place the new Vretti thermal paper roll into the paper compartment, ensuring the paper feeds out from the bottom of the roll towards the print head. The thermal side of the paper (usually the outer side) must face the print head.
- Pull a small length of paper out past the printer's cutting edge.
- Close the paper cover firmly until it clicks into place. Ensure there are no wrinkles or obstructions.
- Perform a test print to confirm correct loading and print quality.
4.2. Identifying the Thermal Side
If you are unsure which side of the paper is thermal, gently scratch the surface with a fingernail or apply a small amount of heat (e.g., from a lighter held briefly at a safe distance). The thermal side will show a dark mark where heat was applied.
5. Maintenance and Storage
- Storage Conditions: Store thermal paper rolls in a cool, dry place, away from direct sunlight, high temperatures, and humidity.
- Avoid Chemicals: Do not expose thermal paper to chemicals, oils, or plasticizers (e.g., from PVC binders or plastic bags) as these can degrade the thermal coating and cause fading.
- Handling: Handle rolls by the edges to avoid transferring oils from hands to the thermal surface, which can affect print quality.
- Longevity: While designed for durability, thermal prints can fade over time, especially when exposed to heat, light, or certain chemicals. For long-term archiving, consider making copies of important receipts.
6. Troubleshooting
- Faded or Blank Prints:
- Ensure the paper roll is loaded correctly with the thermal side facing the print head.
- Check if the printer's print head is clean. Refer to your printer's manual for cleaning instructions.
- Verify that the printer's heat settings are appropriate for thermal paper.
- Paper Jams:
- Ensure the paper roll is properly seated and not too tight or loose in the compartment.
- Check for any torn or crumpled edges on the paper.
- Make sure the paper cover is fully closed.
- Red Line Appears Too Early/Late:
- The red warning line is an indicator for low paper. It appears when approximately 1-2 meters of paper remain. This is a standard feature and not an error.
