;
Note: Warning and Fault Messages are not displayed when the printer is in Menu or Test Mode.

The printer measured too
small a difference between
the ‘empty’ and ‘gap’
sensor readings. Transparent backing or notched media
typically gives this indication. In this case,
there may be a slight delay in the ‘Out of
Stock’ indication, after the media supply is
emptied; no action is required.
