What action is likely to fix registration issues with a digitizer pad?

Recalibrating the digitizer pad is the most appropriate action to address registration issues. This process involves adjusting the settings so that the input from the stylus accurately corresponds to the location on the screen. Over time or due to manufacturing variances, the alignment between the stylus and the digitizer can become misaligned, leading to input errors where touches do not register precisely where intended.

When recalibration is performed, the device can reassess the relationship between touch input and screen output, ensuring that any discrepancies are minimized. This adjustment is crucial for precise applications, such as graphic design or handwriting recognition, where accurate tracking of the stylus is essential for effective use.

Other actions like replacing the stylus or updating drivers might resolve different types of problems, such as hardware malfunctions or software compatibility issues, but they do not directly address the calibration alignment that specifically causes registration errors. Similarly, changing sensitivity settings can alter the responsiveness of the digitizer but does not resolve the core issue of misalignment that recalibration addresses.
