* PRODUCTION COUNTERMEASURE:
The following has been implemented to prevent leakage:
The front and rear drum blades have been changed to scrape
off
ink build-up on the ink roller edges.
A groove has been added to the edge of the front and rear bank plates. This prevents accumulated ink on
the ink roller edges from
being
scraped off
by the edge
of the bank plates and falling inside of the drum
screen.
A hole has been added to the front and rear side piates of the ink roller unit to allow installation of the new
drum blades.
