xTool Creative Space Error Message: Severe Nozzle Blockage

 

Possible causes

  • The print head nozzles are severely clogged with dried ink or debris.
  • The ink tubes supplying ink to the print head are clogged or obstructed.

 

Troubleshooting procedure

Please identify which scenario best describes when the error occurred.

 

Scenario A: Error occurs during first-time setup

If this error appears while you are setting up your device for the very first time:

Complete the Initial Configuration

  • Follow all on-screen prompts on the printer's LCD display to finish the first-time setup.

Recalibrate the System

  • In xTool Creative Space software:
    • Navigate to: Device settings > Calibration > Automatic calibration
    • Follow the prompts to complete the calibration process. This recalibration after the initial setup often resolves encoder errors that occur during the setup phase.

 

Scenario B: Error occurs during regular use

STEP1: Clear print head clogs

  • Address Print Head Blockage
  • Maintain Optimal Operating Conditions
    • Keep your printer powered on to maintain automatic maintenance procedures.
    • Operate the printer in suitable temperature and humidity conditions.
    • Use the printer at regular intervals.
    • Perform routine cleaning and maintenance to prevent print head blockages.
  • Evaluate Results
    • If the print head cleaning solutions are effective (the printing test shows significant improvement), the issue was likely caused by print head blockage.
    • If printing tests show no improvement even after manual deep cleaning of the print head, proceed to the next solution.

 

 

STEP2: Check & clear ink-tube blockages

  • Inspect ink tubes for possible clogging.
  • Please proceed to the "Still experiencing issues?" section below to contact xTool Customer Service for further diagnosis and assistance.

 

Preventive measures

To prevent "Severe Nozzle Blockage" errors in the future:

  • Keep the Printer Powered On: It's generally recommended to leave your printer powered on (in standby mode). This allows the printer to perform its automatic maintenance cycles, which help prevent ink from drying in the nozzles.
  • Maintain Optimal Environment: Operate the printer within the recommended temperature and humidity ranges specified in the user manual. Extreme conditions can affect ink viscosity and promote clogging.
  • Use Regularly: Printing periodically (even just a small test print or nozzle check) helps keep the ink flowing. Long periods of inactivity increase the risk of clogging.
  • Perform Routine Maintenance: Regularly follow the recommended cleaning and maintenance procedures outlined in your xTool Apparel Printer user manual.
