Cleaning the thermal printhead

After prolonged use, the thermal printhead picks up fibres from the

media passing under it. These fine fibres collect and compact on

portions of the printhead, blocking the contact it makes with the

paper during a plot and causing faded patches. Poor contact between

the printhead and paper may also cause the affected heating

elements (nibs) to fail prematurely because of improper heat

dissipation to the paper.

Clean the printhead every time you install a new roll of paper or

film.

1. Turn the plotter power off.
