3. Pull out the bushings on the right and left ends, and the gear, from the BTR removed from its
holder. Install the bushings and the gear to the new BTR.
Note: Do not touch, or dirty with chemicals or toner, the surface of the BTR, as indentations in
and dirt on the surface of the BTR adversely affect the quality of the printed image. When
handling the BTR, hold onto the shaft and bushings of the roller. To avoid contaminating the new
BTR, always place it on a new, clean sheet of paper.
