6 Insert most of the cleaning card under the printhead, and then
lower the printhead.
7 Pull out the cleaning card and raise the printhead.
8 Wait for approximately 30 seconds to allow the cleaning fluid to
dissolve the residue.
9 Repeat Steps 5 through 7.
10 If necessary, repeat the process with a fresh cleaning card.
11 Allow the cleaned parts to dry before loading media and ribbon.
The printhead is subject to wear both from the direct thermal media
or ribbon and from the rapid heating and cooling process during
printing. So, you need to periodically replace the printhead.
How often you need to replace the printhead depends factors such as
the print images, the type of direct thermal media or ribbon in use,
the amount of energy to the printhead, the print speed, and the
ambient temperature.
You must turn off the power before replacing the printhead. The
firmware can only detect the new printhead when the printer is
restarted.
