4.1
Cleaning
To
maintain
quality
and
prolong
the
printer’s
life,
you
need
to
perform
some
routine
maintenance.
Daily
maintenance
should
be
done
for
high
volume
printing,
and
weekly
for
low
volume
printing.
Warning
Always
turn
off
the
printer
before
cleaning.
4.1.1 Printhead
It
is
essential
to
keep
printhead
clean
if
you
want
the
best
quality.
We
strongly
recommend
that
you
clean
the
printhead
when
you
load
a
new
media
roll.
If
the
printer
is
operated
in
critical
environment,
or
the
quality
declines,
you
need
to
clean
the
printhead
more
frequently.
Keep
in
mind
these
things
before
you
clean:
Keep
the
water
away
in
case
of
corrosion
on
heating
elements.
If
you
just
finish
printing,
wait
until
the
printhead
cools
down.
Do
not
touch
the
printhead
with
bare
hands
or
hard
objects.
Cleaning
steps:
1.
Moisten
a
soft
cloth
or
a
cotton
swab
with
ethyl
alcohol.
2.
Gently
wipe
the
printhead
in
one
direction.
That
is,
wipe
it
only
from
left
to
right
or
vice
versa.
Do
not
wipe
back
‐
and
‐
forth,
in
case
dust
or
dirt
attaches
to
the
