Action
1. Install 2 modified fly wheels (P/N: M0771294) in between the mainframe and the default
fly wheel, so that a total of 3 fly wheels are installed per station. Secure the fly wheels
with TAPPING SCREW:4X12 (P/N: 04514012N) (x3). See “Installing the Modified Fly
Wheels” for the detailed procedure.
2. Apply the following firmware versions.

3. Change the following SP values:
SP
Modified Default Remarks
SP2-992-001 0.5 0 Drum process speed increases 0.5% and
becomes level with the ITB rotation speed.
As a result, the main scan starting point
shifts approx 0.75 mm towards the leading
edge on both sides of the paper.
Image position must be readjusted in the
Adjustment Settings for Skilled Operators
menu to compensatefor the shift.
SP2-993-001 1 0 Cut-off frequency for drum revolution
control is reduced from 30Hz to 13Hz to
prevent resonance vibration.
4. Enter the Adjustment Settings for Skilled Operators menu and adjust the main
scan starting point in “0101: Adjust Image Position With Feed Direction” for both
front and back sides to compensate for the image position shift as a result of the
SP modification in the previous step.
