Reinstallation tip A small grounding spring is under the right transfer-roller bearing.
When reinstalling the transfer roller, position this spring correctly under the right bearing.
Reverse the removal process to install the new transfer roller. Then reinstall the paper
guide by gently pressing the two ends of the guide onto the transfer-roller bearings until
the clamps snap into place. Rotate the paper guide down until the tabs on both ends
engage.
