10. Installation Position of the Scanner Drive Assembly
Loosen the four screws of the scanner drive assembly; then, while pushing the scanner drive
assembly against the rear plate (direction of arrow [1]), move it in the direction of the manual feed
tray (direction of arrow [2]) so that it touches the pulley base and the lens gear. In this condition,
tighten the screws, and confirm that there is play between the lens gear and the gear of the lens drive
capstan.
