Troubleshooting Thermal Printer Issues After Paper Roll Replacement

The thermal receipt printer is one of the most commonly used POS peripherals in the retail and restaurant industries. Sunany occasionally receives feedback: the printer starts acting up after paper roll replacement. Based on our experience, the issue usually stems from the paper roll and is often related to user operations.

If your printing was working fine before, but after replacing the paper roll, it’s either printing blank pages, not printing anything at all, or producing extremely blurry text and graphics, it’s likely a paper-related issue.

Thermal Paper Loaded Incorrectly: Make sure that you have correctly loaded the thermal paper. Due to the printing characteristics of thermal printers, only one side of the paper can achieve proper printing. Try reloading the paper with the other side facing up to resolve the problem.

Expired Thermal Paper: Check the purchase date of your thermal paper. The surface coating of thermal paper contains heat-sensitive materials that can degrade over time, leading to unclear or incomplete printing. Prolonged exposure to light or sunlight can also render thermal paper unusable.

There’s also a slight possibility that the print head is damaged and needs to be replaced.

If none of the above solutions resolve the issue, consider reaching out to the printer supplier for technical support.
