Why is my drawing tablet pen not registering pressure?

The most common causes are: an outdated or corrupted tablet driver, the application not receiving pressure data from the driver (check the application's brush settings), or a Windows Ink conflict. On Windows, disable Windows Ink in the tablet driver settings — many drawing applications route pressure through their own protocol and Windows Ink causes conflicts.

Why does my Wacom tablet have a yellow exclamation mark?

A yellow exclamation mark in Device Manager means Windows cannot load the tablet driver. Uninstall the driver completely using Wacom's Tablet Driver Cleanup Utility (available from Wacom's support page), restart, then reinstall the latest driver from Wacom's website.

Why does my drawing tablet work on one computer but not another?

The driver is not installed on the second computer, or an older version is installed. Download and install the current driver from the manufacturer's website on each computer you use. USB drivers transfer is not possible — each computer needs its own installation.

Why does my pen hover cursor not align with the actual stroke?

Parallax alignment issue — common on pen displays (tablets with screens). Calibrate the pen using the tablet driver's built-in calibration tool. On external monitors, check that the tablet is mapped to the correct monitor in the driver settings.

Drawing Tablet Not Working: 8 Fixes for Connection, Pen, and Driver Issues

Fix a drawing tablet that won't connect, loses pressure sensitivity, or has a pen that doesn't register. Step-by-step troubleshooting for Wacom, Huion, and XP-Pen tablets on Windows and Mac.

A drawing tablet that stops working mid-session or refuses to connect is one of the more frustrating hardware failures because the symptoms are similar regardless of whether the problem is the cable, the driver, the pen, or the software.

This guide works through each cause in the order most likely to solve the problem fastest.

Fix 1: Unplug and Replug the USB Connection

Before any software troubleshooting: disconnect the USB cable from both the tablet and the computer, wait 10 seconds, and reconnect. A surprising number of connection failures are resolved this way. If you're using a USB hub, plug directly into a port on the computer instead.

Fix 2: Restart the Tablet Driver Service

The tablet driver runs as a background service. If it crashed or failed to start:

Windows:

Open Task Manager (Ctrl+Shift+Esc)
Go to the Details tab
Look for Wacom_Tablet.exe, HuionTablet.exe, or PentabletService.exe
If present, right-click and End Task
Relaunch the driver from the Start menu or restart the computer

Mac:

Open System Preferences > Wacom Tablet (or equivalent)
Click the gear icon and choose Restart Tablet Driver

Fix 3: Reinstall the Driver

Driver corruption is the most common cause of persistent issues:

Download the current driver from the manufacturer's website (not from Windows Update or the disc)
Uninstall the existing driver through Control Panel / System Preferences, not just by deleting files
For Wacom: use the Wacom Tablet Driver Cleanup Utility before reinstalling
Restart before installing the new driver
Install the driver before plugging in the tablet

Fix 4: Disable Windows Ink

Windows Ink creates conflicts with many drawing applications. When Windows Ink is active, pressure data sometimes routes through Windows instead of the tablet driver:

Open the tablet driver software
Find the "Mapping" or "Options" tab
Disable "Use Windows Ink" or "Windows Ink" toggle
Restart Photoshop, Clip Studio, or whatever application you use

Fix 5: Check Application Brush Settings

The tablet may be working correctly but the application is set to ignore pressure. In Photoshop, click the brush tool, open the brush settings, and confirm "Shape Dynamics" has "Size Jitter" set to "Pen Pressure." In Clip Studio Paint, check the Sub Tool Detail window for pressure curve settings.

Fix 6: Test the Pen in the Driver Software

Open the tablet driver settings and find the diagnostic or test area. Move the pen across the surface — you should see the cursor move. Apply pressure — the pressure meter should respond. If the pen doesn't register in the driver's own test area, the pen hardware is the issue, not the software.

Fix 7: Try a Different USB Port or Cable

USB ports on the same hub share bandwidth. A high-bandwidth device on the same hub (external SSD, webcam) can crowd out the tablet. Try a USB port on the other side of the computer, or on a different chipset.

USB-C to USB-A adapters sometimes fail to carry the data lines a tablet needs. Try a different cable.

Fix 8: Check for Software Conflicts

Some VPN clients, screen recorders, and pen-related software conflict with tablet drivers:

Screen capture software that hooks into pen events (Lasso, Snip & Sketch in extended mode)
VPNs that intercept device communications (rare but reported)
Old versions of Photoshop that pre-date the tablet's driver

If the tablet works immediately after a clean Windows startup but fails after certain programs load, use the Windows Task Manager startup tab to identify and disable potential conflicts one at a time.
