Diagnosing and Fixing an HP DesignJet Printer System Error 21:10
Today, our HP DesignJet printer repair took us to assist one of our longstanding business customers. The HP DesignJet plotter displayed an error message: System error 21:10 ‘Severe error: 0 X 3010002 Task
file: sequence.c:758′. This common error message usually indicates an issue with the service station. However, before jumping to conclusions, there are a few troubleshooting steps to try:
- Unplug the Power Cable
- Open the Top Window Door
- Move the Carriage Assembly
- Move the carriage assembly all the way to the left, away from the service station on the far right. Do not force it if it doesn’t move freely.
- Check for Obstructions Inside the Machine
- Inspect the Carriage Belt
- Ensure the carriage belt looks intact and is not disintegrating or loose.
- Clean the Long Chrome Carriage Rod
- Use synthetic oil to clean the rod.
- Check the Trailing Cable
- Ensure the trailing cable is flat and moves freely.
- Clean the Encoder Strip
- Use a non-abrasive, lint-free cloth to clean the encoder strip.
- Remove the DesignJet Printheads
- Reboot the Plotter
- Reinsert the Printheads
- Check the Firmware
If these steps do not resolve the issue, you will likely need to replace the service station. Additionally, consider replacing the encoder strip if it appears damaged.
