Hi Dan,
I think this is a known hardware problem of the printer :-(
It thinks the ITB transfer kit needs to be replaced. The percentages
displayed are estimates from the formatter while the actual indication of
life over comes from a sensor on the ITB assembly itself. So you can
either reset the pagecount in the service menu or reset the ITB unit: pull
out the middle draw and the ITB (transfer belt) is right in front of u.
Maybe a cold reset would be fine also (hold the start button while
powering on the printer.
hope this helps
