Important
Gap pad/putty pad replacement guidelines

  • To identify the gap pad/putty pad location and orientation, see Gap pad/Putty pad identification and location.

  • Before replacing the gap pad/putty pad, gently clean the interface plate or the hardware surface with an alcohol cleaning pad.

  • Hold the gap pad/putty pad carefully to avoid deformation. Make sure no screw hole or opening is blocked by the gap pad/putty pad material.

  • Do not use expired putty pad. Check the expiry date on putty pad package. If the putty pads are expired, acquire new ones to properly replace them.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.
