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. Fix the fly wheels with
TAPPING SCREW:4X12 (P/N: 04514012N) (x3). See “Installing the Modified Fly
Wheels” for detailed procedure.
2. Apply the following firmware versions.
Part number Version
Web Support D0956083 1.03
Engine D0955253 1.007:16
System/Copy D0956081 1.05
3. Change the following SP values:
SP Modified Default Remarks
SP2-992-001 0.5 0 Drum process speed increases 0.5% and
levels with the ITB rotation speed. As a
result, the main scan starting point shifts
approx 0.75mm to the leading edge on
both sides of the paper.
Image position must be readjusted in the
Adjustment Settings for Skilled Operators
menu to compensate 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 the image position shift as a result of the SP
modification in the previous step.
If the results are accepted by the customer, complete the procedure.
If the results are unaccepted by the customer, do the following step.
5. Register the paper in use to the Paper Library.
