6. Troubleshooting
6.1 Printing Issues
- No Printout: Ensure the 'OFF ON PRINT ITEM' switch is set to 'ON'. Verify that thermal paper is correctly installed and that it is indeed thermal paper.
- Faint Print: Replace the thermal paper roll. If the issue persists, ensure the paper is installed correctly.
- Unexpected Printouts: If the printer activates when not expected, especially when the print switch is off, this indicates an anomaly. Ensure the calculator is used as intended.
6.2 Display Issues
- Display Washes Out: The fluorescent display may appear to wash out or become unreadable from certain viewing angles, particularly when looking down from above. Adjust your viewing angle for optimal clarity.
