5. MAINTENANCE
5.1 CLEANING AND CARE
 To ensure that your D03S operates correctly, the entire unit should be cleaned on a regular
basis.
 Turn off the power to the controller.
 Turn off and isolate the air supply to the printer body.
 Remove the printer cassette and clean inside the printer body. Since there are electronic
components inside this case, DO NOT use water to clean the unit. Isopropanol cleaning wipes
can be used for this purpose.
 To clean the debris from the inside of the printer body, DIKAI recommend the use of a soft bristle
brush.
5.1.1 Care of the Printhead
Although purpose-built for its application, the print head is still subject to wear and tear. Careful
consideration at the time of installation and regular preventative maintenance can significantly help to
maximize print head life.
The most frequent cause of print head damage is abrasion-either from ingress of airborne particles or
from an abrasive substrate surface. Consequently, print head life varies considerably among
substrate materials and among applications.
The thermal ribbon protects the printhead against wear. With use of various ribbon widths and an
abrasive substrate, it is possible that the unused, unprotected, section of the printhead is subjected to
wear and damage. Usually, abrasive substrates have preprinted inks. Particularly, some red inks
maybe more abrasive than other colors.
Procedures for all thermal transfer printers follow:
- Regularly clean the printhead. The frequency of cleaning is entirely application and environment
specific.
- To minimize printhead wear, always use the minimum air pressure than delivers an acceptable print
quality. Never exceed the maximum air pressure recommended for the particular D03S used.
- Use the minimum darkness setting that delivers the required print quality.
You’d better clean it before daily production:
1. Turn off the power to controller and remove the ribbon cassette. Allow the printhead to cool to
normal room temperature before proceeding in order to prevent the possibility of thermal shock
damage.
2. Please use printing head cleaning wipe provided by DIKAI or a soft cloth in Isopropanol (Refers
to the below image).
3. Better clean the print head once a day if the printer keeps running.
4. Please DO NOT use any water, sharp items or abrasive materials to clean the print head
