3.5 Cleaning the Printhead
The printhead should be cleaned at regular intervals. These depend on machine
use, operating environment, and choice of thermal ribbon.
1. Turn off the power to the controller and remove the ribbon cassette.
2. Allow the printhead to cool to normal room temperature before proceeding in
order to prevent the possibility of thermal shock damage.
3. Use a cotton swab or a soft cloth soaked in Isopropanol solvent to remove any
residue from the printhead. Take care not to use excessive amounts of
solvent.
The print line is located on the bevelled edge of the printhead.
Use great care not to damage the printhead during cleaning. UNDER NO
CIRCUMSTANCES should abrasive materials, or tools such as screwdrivers, be
used for cleaning the printhead.
Replace the ribbon cassette and check the print quality. If the overall quality is
poor, or some of the dots are not printing, the printhead may need to be adjusted
or changed.
