# TSG: Pen skipping vertical or horizontal bands
## Overview
This will manifest as vertical or horizontal bands that the pen seems to ignore. These bands will extend across the full active area of the tablet.
## Examples
Then missing horizontal bands will look like this:
And missing vertical bands will look like this:
## Causes
* Usually it seems to be a hardware issue with the digitizer in the tablet.
* It **might** also be caused by electromagnetic interference
## Things to try
Again, this is usually a hardware issue that cannot be fixed. But it is worth trying some of these steps just in case they might help.
* Restart computer
* Reinstall driver
* Test tablet with another computer
* Check if it happens with multiple applications
* Check if it happens in the pressure test region of the tablet driver
* If the problem persists, contact support: [Contacting support](/drawtab/basics/support.md).
