Troubleshooting faded receipts on the Hantle 1700W terminal. Focus on thermal print head cleaning, power fluctuations, and environmental factors in a retail setting.
The power supply voltage should be within the manufacturer's specifications.
Use only approved thermal paper for optimal print quality.
Regularly cleaning the thermal print head prevents debris buildup and ensures proper heat transfer.
Thermal printers rely on heat to activate dye in the thermal paper. Insufficient heat output from the print head results in faded prints. This can be caused by voltage drops affecting the print head's heating element, signal attenuation between the main board and print head controller, or a dirty print head preventing efficient heat transfer.
Receipts are printed with reduced contrast, appearing light or faded. Text and graphics may be incomplete or barely visible.
Safe Handling: Always unplug the Hantle 1700W from the power outlet before performing any cleaning or inspection. Ensure the power outlet is properly grounded. Avoid static discharge (ESD) by touching a grounded metal object before handling the terminal, especially in dry environments. Do not use excessive force when cleaning the print head.
Regularly clean the thermal print head (monthly) to prevent debris buildup. Ensure the terminal is placed in a location with stable power and controlled humidity. Use only approved thermal paper. Provide cable strain relief to prevent connector damage.
Some Hantle terminals have a diagnostic print function accessible through a specific key combination. Consult the Hantle 1700W service manual to activate the diagnostic print and assess print head functionality. Also consider using a regulated power supply (UPS) to stabilize voltage fluctuations.
