2-18 Phaser 8400 Color PrinterTransfix SystemThe transfix roller applies pressure to the back side of the paper as it moves betweenthe transfix roller and drum. This pressure transfers the image from the drum to thepaper. A set of springs determines how much pressure the transfix roller applies in theload module against the drum. The pressure must be uniform across the length of thetransfix roller to avoid paper wrinkles and light spots on the prints.After the transfix roller is engaged, the drum rotates to advance the paper during thetransfix process. The drum continues to advance the paper until the transfix roller isdisengaged. The transfix roller is lifted and lowered by the action of the process drive.All gears move to rotate the transfix camshaft to bring the transfix roller into contactwith the drum. The gears reverse to rotate the transfix roller back to its originalposition, except when printing from Tray 1 or on envelopes. The transfix load springsand double lever arms increase the force when the camshaft is engaged.WarningNever attempt to adjust or increase the transfix pressure on the springs.DrumTransfixcamTransfix load arms8400-119Transfix loadmoduleTransfer rollerTransfixloadspring
