detected.

3-12
Possible Solution(s)
Replace the printhead if print
quality becomes unacceptable (see
Section 4.3).
No action required. Typically
caused by transparent media
backing or notched media, this
may result in a slight 'Out of Stock'
indication delay when the supply is
emptied.
The power switch was turned OFF
or AC line voltage has been lost.
Clean the printhead (see Section
2.1.1).
To save the changes, send a host
reset command; or, to discard
changes perform a soft reset (see
Section 2.9).
