Fiber-tip pens will last at least
30
days stored in the carousel. However,
if you do not plan to plot for several days, remove the pens from the
carousel and cap them to ensure a longer pen
life.
Remove drafting pens and cap them immediately after use to prevent
drying and clogging. Drafting pens require cleaning after each use.
Remember that ink dries as quickly in the drafting pen
as
it does on
the plotting media. Here are the maximum times that ink can remain
in a drafting pen in an average environment.

seconds if the pen
is
uncapped and not in use.
•
One day
if
the pen is in a drafting pen carousel.
•
One week if the pen
is
properly capped and stored in a honwntal
position.
