3. 4. 4. 19 DC685 Regi Control Setup Cycle (Registration)
Function Sets or displays the optimal values of skew and the NVM values of other Regi control
correction systems.
• This is the cycle to set the optimal values of the skew and the NVM values of other Regi
Control correction systems, assuming that this is executed at factory shipment and at LSU
(ROS) replacement in the field. Only this cycle detects and corrects the skew and
magnification balance.
• There are four functions of the Regi Control Setup Cycle. These functions work
independently. Usually, they are performed in the order of 1-2-3. Perform Procedure 4. Skew
Rough Setup only when an error is displayed during Procedures 2 and 3. For details, refer to
Chapter 2 ADJ1.1.6 Regi Control Adjustment.
