When

The TOC Curve Check can be started manually following the replacement and flushing
of the Q-Pak® pack. The System automatically performs a TOC Curve Check once per
day. So, if the TOC Curve Check is not started manually following the consumables
replacement, it will be done automatically within the next 24 hours or sooner.
