Warning:
When replacing the RIP board, verify the cable from the high-voltage power supply is seated
properly. The cable may have come loose from the HVPS.
•
Print a few pages to verify the installation. If the pages are blank, confirm that the high-voltage
power supply cable is properly seated. The connector may have been loosened at the HVPS.
• A blank page that should have toner on it could be an indication that toner is applied to the ITU
belt but not transferred. Therefore the toner goes into the ITU cleaner which cannot process
massive amounts of toner. It is important to prevent extensive blank pages from being processed
if they should have toner on them.
•
When installing the RIP board, make sure to route all of the cables through the correct openings.
