Troubleshooting thermal printer issues on a Poynt GoDaddy Terminal: Diagnostics, solutions, and preventative maintenance for clear receipts.
Movement can loosen cables or damage components.
Using incompatible paper can cause print quality issues.
Error messages can provide clues to the underlying problem.
Thermal printers rely on heat-sensitive paper and a print head containing numerous small heating elements. Voltage fluctuations, data transmission errors, or a degraded print head can cause incorrect heating patterns, resulting in illegible output. External electromagnetic interference (EMI) or electrostatic discharge (ESD) may also disrupt the printer's control circuitry.
Receipts are printing gibberish characters instead of expected text.
Avoid operating the terminal near liquids or in excessively humid environments. Ensure adequate ventilation around the terminal to prevent overheating. Do not attempt to open the terminal casing, as this may damage the device and void the warranty. High ESD risk in dry environments; ground yourself before touching the device.
Regularly clean the print head to prevent buildup of residue.,Use only approved thermal paper rolls.,Ensure the terminal is plugged into a surge protector to protect against voltage fluctuations.,Implement cable strain relief to prevent damage to the printer cable.,Maintain a clean and static-free environment around the terminal, especially during dry winter months. Use anti-static mats if necessary.
Try printing a test receipt from the terminal's diagnostic menu (if available). This bypasses the regular software and can help isolate hardware issues. If the test print is clear, the problem likely lies with the software application generating the receipts.
