Technical analysis of persistent paper jam errors on Entra.Station card terminal. Includes troubleshooting steps and preventive measures.
Impact can dislodge cables or damage sensor alignment.
Incorrect paper types can cause jams.
Additional symptoms can provide further clues.
Paper jam errors can stem from several hardware or software issues. The printer module relies on optical sensors to detect paper presence and movement. Voltage fluctuations or signal attenuation within the sensor circuit can cause false positives. Static discharge (ESD) during dry environments may temporarily interfere with sensor readings or the printer control logic. Baud rate mismatches or data corruption in the communication between the main system and the printer module can also manifest as errors.
Entra.Station reports a persistent "Paper Jam" error, even after manual clearing of the paper path.
Always safely handle the Entra.Station by unplugging the power adapter before any inspection or cleaning. Avoid using excessive force when clearing paper jams. Do not insert any sharp objects into the printer module. Be aware of potential ESD hazards, especially during dry weather. Ensure adequate ventilation around the device to prevent overheating.
Regularly clean the exterior of the Entra.Station. Ensure the device is placed on a stable surface to prevent cable strain. Avoid operating the device in excessively dusty or humid environments. Use only approved paper types for the printer module.
Try using a can of compressed air to gently blow out the optical sensors inside the paper path. Aim short bursts of air to dislodge any microscopic debris. Be extremely careful not to damage the sensors.
