When the DP main PWB is replaced with a new one, carry out the following procedure.
1. Clean the CIS roller and contact glass (CIS).
2. Perform maintenance mode U411 (Adjusting the scanner automatically) (see page 1-3-36).

If problems such as white lines appear on the test copy, repeat the procedure from steps 1 and 2
