What To Do If My Pen Is Drawing Broken Lines?

Broken lines on a digital pen can stem from several sources, broadly categorized as hardware and software issues. Let's explore each:

1. Hardware Issues:
   1. Pen Tip Wear/Damage: The most common cause. Over time, the pen tip can wear down, become misaligned, or suffer damage (scratches, cracks). This leads to inconsistent contact with the writing surface, resulting in broken or intermittent lines. 
   2. Pen Pressure Sensor Problems: Digital pens rely on pressure sensors to detect the force applied. If this sensor malfunctions or becomes dirty, it may not register pressure consistently, leading to broken lines or inconsistent line thickness.
   3. Connection Issues or Internal Component Failure: A loose or faulty connection between the pen and the tablet can interrupt the signal, causing lines to break. Like any electronic device, internal components within the pen can fail and can manifest as erratic behavior, including broken lines.
   4. Dirty Sensor: Dust, debris, or ink residue can accumulate on the pen tip or the pressure sensor, interfering with the signal and causing intermittent lines.
2. Software Issues:
   1. Driver Issues: Outdated, corrupted, or missing drivers can lead to various problems, including broken lines. Ensuring your drivers are up-to-date is crucial.
   2. Software Glitches: Bugs or conflicts within the operating system or the application you're using can sometimes interfere with the pen's functionality. Restarting your device or the application can often resolve temporary glitches.
   3. Calibration Problems: If the pen is not properly calibrated, it may not accurately register the pen's position, resulting in broken or inaccurate lines. Recalibrating the pen is often a simple solution.
   4. Application Settings: Some applications have settings that affect pen behavior. Incorrect settings, such as sensitivity or pressure levels, might cause broken lines.

Troubleshooting Steps:

To diagnose the problem, try these steps:

1. Check the Pen Tip: Inspect the pen tip for wear, damage, or debris. Clean it gently if necessary. Consider replacing the tip if it's worn.
2. Check the Connection: Ensure the pen is properly connected to the device. Try restarting both the tablet and the device (computer or smartphone).
3. Update Drivers: Check for and install the latest drivers for your tablet.
4. Calibrate the Pen: Follow the instructions for recalibrating your pen with the tablet: How to Calibrate Your Pen Display?
5. Restart the Device and Application: A simple restart can often resolve software glitches.
6. Adjust Application Settings: Check the application's settings related to pen pressure sensitivity, line thickness, and other relevant parameters. Experiment with different settings to find an optimal configuration.
7. Try a Different Application: If the problem only occurs in one application, it may be a software issue specific to that application.
8. Reinstall the Application (if applicable): If the problem is specific to a single application, reinstalling it might resolve software conflicts.
9. Contact Support: If none of these steps work, contact our support team for assistance. Email the following to service@huion.com:
   1. Serial # (found on the back of your tablet, which starts with S/N)
   2. Your computer operating system and its version
   3. Driver version (on the driver, go to Settings > "About" tab)
   4. Firmware version (on the driver, go to Settings > "Device" tab)
   5. Your drawing software and its version. Include other software you tested that has the same issue.
   6. Link to a video that captures your issue. It is recommended that the video be uploaded to an online storage such as Google Drive, Dropbox, iCloud, etc., remove the restriction, and share the unrestricted link.

By systematically investigating these potential causes, you should be able to pinpoint the source of the broken lines and find a solution.
