Troubleshooting paper jams in Epson TM-T88VI thermal printers during dry winter months. Focus: ESD, humidity, and paper handling.
Knowing the paper composition helps assess its static potential.
Humidity is a key factor in static generation.
Regular cleaning prevents dust buildup and sensor interference.
Low relative humidity increases static electricity generation during paper movement. ESD can interfere with the paper feed sensor, causing false jam detection. The TM-T88VI's internal circuitry is susceptible to voltage spikes from ESD. Baud rate and signal attenuation are unlikely contributing factors in this scenario.
Recurring paper jams in dry environments, specifically during winter months. Potential static discharge felt when touching the printer or paper roll.
Maintain consistent humidity levels. Regularly clean the paper path to prevent dust buildup. Use recommended thermal paper. Inspect and maintain ground connections.
Try gently wiping the paper feed sensor with a dry, lint-free cloth after Safe Handling (unplugging). Static cling can cause false readings. Check the printer's firmware version and update if a newer version addresses ESD issues. Also, move the printer away from other sources of EMI such as large power supplies or cordless phone bases.
