Model U-P1
The following modification has been applied to the production machines.
•
A cleaning blade has been added to the ITB cleaning section.
•
The material of the OPC-belt cleaning blade has been changed (This has already been applied to the
production machine since 2003 October production.).
•
Due to the additional cleaning blade in the ITB cleaning unit, an excessive load will be placed on the
cam of the ITB cleaning contact mechanism at the rear of the machine. This can cause the cam to
dislodge from the shaft. To correct this, a metal retaining ring was added to secure the cam (instead of
a plastic snap ring) from the following cut-in serial numbers. (This has already been applied to the
production machine since 2003 August).
Retaining ring modification from Plastic to metal (Refer to MB G071012 for details)

You must do these before you install either the new PCU or new development unit (or both) in machines with
serial numbers prior to above cut-in numbers:
•
Add the cam stopper to the ITB cleaning cam (The cam stopper is included in the New PCU box for
new PCU settings only)
•
Update the firmware to controller v2.30 or later and BCU v1.48d or later.
•
Change SP mode settings (PCU settings or development unit settings)
•
Perform color registration adjustment (SP2-950: for New PCU installation only)
To ensure good printing, the development unit has also been modified.
