Make sure the chart is not hung up or restricted.
Make sure the pen does not have too much tension, pinching the chart to the dial plate.

Is the Chart Recorder sitting on or mounted to a surface prone to vibration?
For Temperature units try removing the unit from the application and placing it in an isolated, low air flow environment like a zip lock freezer bag or desk drawer. If the pen traces straighten out, the traces may have actually been caused by the changes in your application.
