Original reading start sensor adjustment

When the RADF board or the original reading start sensor (sensor section or prism) is replaced,
be sure to perform this adjustment. If not, paper jams (E721, E725, E774) or operational
problems may occur.

(2) Key in [3210] and then press the [START] button.
Notes:
• Be sure to close all of the RADF cover before the adjustment is performed.
• Check that there is no paper on the original reading start sensor so that the light is not
shielded.

the prism.
