- Product
- PDF Editors / Lenovo Tablet
- Device & OS
- Lenovo tablet
- Scenario
- Writing, drawing, or adding handwritten annotations to a PDF document using a stylus or touch input.
- Observed behavior
- Unwanted lines and marks appear on the PDF document where the user's palm rests against the tablet screen.
Ensure your Lenovo tablet's operating system is fully updated, and verify that your stylus is adequately charged and actively paired via Bluetooth if required.
Enable Accidental-Touch Prevention in Device Settings
Adjust your Lenovo tablet's native touch settings to ignore palm inputs while you are actively using a stylus.
Many modern tablets have built-in software features designed to distinguish between a stylus tip and a resting hand. Enabling this feature at the system level ensures it works across all your PDF applications.
Unlock your Lenovo tablet and tap on the gear icon to open the Settings application.
Scroll down and select 'Accessibility', 'Display', or 'Pen & Windows Ink' (if using a Windows-based Lenovo tablet) to find touch-related configurations.
Locate the option labeled 'Palm Rejection', 'Accidental-touch prevention', or 'Ignore touch input when I'm using my pen' and toggle the switch to the ON position.
Use an Active Stylus with Hardware Palm Rejection
Upgrading to a compatible active stylus provides reliable, hardware-level palm rejection.
Configure Stylus-Only Mode in Your PDF Application
Restrict drawing inputs exclusively to your stylus within the specific PDF app's settings.
Annotate PDFs Smoothly with WPS Office
WPS Office provides robust PDF annotation tools optimized for touch and stylus inputs, reducing accidental marks and ensuring a smooth, uninterrupted writing experience on your tablet.
- 1. Open your PDF in WPS: Launch the WPS Office app on your tablet and open the PDF document you wish to write on.
- 2. Access the Annotation Tools: Tap on the 'Annotate' or 'Edit' tab located at the top menu to reveal the drawing toolbar.
- 3. Select the Pen Tool: Choose the Pen tool, adjust your preferred ink thickness and color, and begin writing smoothly.
- 4. Save Your Notes: Once your handwriting is complete, tap the save or checkmark icon to securely apply the annotations to your document.
Frequently Asked Questions
Why does my tablet register my palm when writing?
Capacitive touch screens are designed to register any conductive object, including human skin. Without hardware or software palm rejection enabled, the screen cannot differentiate between a stylus tip and your resting hand.
Does every stylus support palm rejection?
No, basic capacitive styluses (often equipped with a soft rubber tip) merely mimic a finger and do not support palm rejection. To utilize this feature, you need an 'active' stylus designed to communicate digitally with your specific tablet.
How can I quickly erase accidental palm marks in my PDF?
Most PDF editing applications feature an 'Undo' button (usually an arrow pointing left in the top toolbar) that lets you instantly revert accidental strokes. Alternatively, you can select the Eraser tool to manually rub out unwanted marks.
