Patent ID: 8126362

Claim:
A printer comprising: an intermediate imaging member; a transfer roller located proximate to the intermediate imaging member; a displaceable linkage coupled to the transfer roller to move the transfer roller from a first position to a position at which the transfer roller engages the intermediate imaging member to form a transfer nip with the intermediate imaging member and to return the transfer roller to the first position; and a controller coupled to the displaceable linkage, the controller being configured to measure movement of the transfer roller from the first position to the position where the transfer nip is formed, and to compute a media thickness from a measured movement of the transfer roller from the first position to the position where the transfer nip is formed with the intermediate imaging member without an image substrate being in the transfer nip and a measured movement of the transfer roller from the first position to the position where the transfer nip is formed with an image substrate in the transfer nip between the transfer roller and the intermediate imaging member.
