Purging (or priming) the Filters

After a main ink filter change, the filter must be completely filled with ink before the system is run. For
this purpose, a Filter Purge option is available from the DIAGNOSTICS menu.

This procedure should only be performed by an authorized service engineer following filter replacement.
