Care & Maintenance

12 Monthly Check

The unit should undergo a technical safety check every 12 months. This safety check should
extend to include the following:
• Visual inspection of the unit and cables.
• Electrical safety tests according to IEC 601-1 and IEC 601-2-25.
• Functional tests according to the Service Handbook.
The test results must be documented.

Cleaning the Print Head

If the printer is used a lot, a residue of printers ink (from the grid on the printer paper) can build
up on the the print head. This can cause the print quality to deteriorate. We recommend
therefore that every month the print head is cleaned with alcohol as follows:
• Remove the paper tray. The printhead is found under, and in from, the paper tray
release catch.
• With a tissue dampened with alcohol, gently rub the print head to remove the ink
residue. If the printhead is badly soiled, the colour of the grid ink will show on the
tissue.
