Technical analysis of Clover printer double printing. Identifies potential causes and provides non-invasive solutions for retail environments.
If yes, a rollback to the previous version may resolve the issue.
If only the Scotiabank app, the issue likely lies within the app's printing routine.
Error codes can pinpoint the specific cause of the double printing.
Printer malfunction can be caused by signal errors from the host device, corrupted print queues, voltage fluctuations affecting the print head, or firmware-level instruction repeats. Electrostatic Discharge (ESD) can also interfere with data transmission and processing.
Do not attempt to open the printer casing. Doing so may damage the device and void any warranties. Ensure the power cable is disconnected during inspection to prevent electrical shock. Handle the device on a dry, non-conductive surface. Avoid contact with metallic objects near the printer’s electronic components.
Regularly inspect printer cables for wear and tear. Keep the printer and surrounding area clean and free of dust. Ensure the power supply is stable and protected from surges. Minimize electrostatic discharge (ESD) risk, especially in dry environments, by using anti-static mats or sprays near the terminal.
If the double printing consistently occurs after a specific transaction type, examine the transaction logs for error codes. A quick factory reset of the Clover device (after backing up important data) can resolve deeply embedded software glitches; however, exercise caution and document current settings before proceeding.
