Troubleshoot Zebra KR403 paper jams: Analyze paper curl direction, thermal printhead maintenance, and environmental factors for optimal performance.
Refer to the Zebra KR403 specifications; typically 60-80 gsm.
Frequency depends on usage, but at least monthly in high-traffic environments.
Consult the KR403 user manual for external tension adjustments, if present.
Paper curl direction affects feeding mechanics. Incorrect curl can increase friction and stress on the printer's motor, potentially causing signal degradation on the control board due to increased load. Thermal printhead temperature fluctuations can affect paper adhesion.

To prevent electrical shock, perform Safe Handling (unplug the power adapter) before any external cleaning or inspection. Ensure hands are dry during operation. Do not insert any foreign objects into the printer mechanism. Cable strain may lead to connection issues.
Store paper rolls in a dry, temperature-controlled environment. Regularly clean the externally accessible paper path with a dry, lint-free cloth. Avoid overloading the paper tray. Periodically check the power cable for strain.
Try fanning the paper stack before loading to reduce static electricity, especially in dry environments. High static can affect paper feed. Consider an external surge protector for power stability to prevent voltage spikes that could damage the printer's control board.
