Citizen CL-S621 Error 1301 Diagnostic Report - Solar Faults | terminalfaults.org

Technical Background:

1301 typically indicates a ribbon or media feed issue, commonly related to sensor malfunction, motor stall, or obstruction in the paper path. This can stem from incorrect media loading, ribbon tension problems, or physical damage to the sensors or drive mechanisms. Signal attenuation due to cable issues could also contribute.

Symptoms:

The Citizen CL-S621 printer displays error 1301 during operation.

Possible Causes:

Incorrect ribbon system: Improperly loaded ribbon obstructs sensor readings.
Media jam: Paper or label stock obstructing the paper path.
Sensor malfunction: Faulty ribbon or media sensors providing incorrect feedback.
Ribbon tension issue: Loose or overtightened ribbon causing feed errors.
Driver malfunction: Corrupted or outdated printer driver.
Communication error: Data transfer interruption between terminal and printer.

Solution:

1

Safe Handling: Disconnect the power cable from the printer.
2

Inspect Ribbon system: Ensure the ribbon is correctly loaded and threaded according to the manufacturer's instructions.
3

Check for Media Jams: Open the printer and carefully remove any jammed paper or label stock.
4

Clean Sensors: Use a lint-free cloth to gently clean the ribbon and media sensors.
5

Verify Ribbon Tension: Adjust the ribbon tension if necessary, ensuring it is neither too loose nor too tight.
6

Restart the printer: Reconnect the power cable to restart the printer.
7

Update Printer Driver: Download and install the latest printer driver from the Citizen website.

Safety Warning:

To avoid electrical shock, always disconnect the printer from the power source before performing any maintenance. Avoid using excessive force when clearing paper jams to prevent damage to the printer's internal components. Static discharge can damage sensitive electronics; ground yourself before touching any internal components.

Prevention:

Regularly clean the printer's internal components with a lint-free cloth. Ensure proper ribbon and media loading techniques. Minimize cable strain on the printer's data and power cables. Schedule regular driver updates.

Expert Tip:

Try performing a factory reset on the printer if the error persists after troubleshooting the above steps. Consult the printer's manual for the specific procedure. A cold boot/power cycle of the terminal might also resolve communication errors.
