BASIC MAINTENANCE & TROUBLESHOOTING
7-6 EPT023558 Issue 1 February 2016
Ribbon back-coating and build-up
Print head contamination from thermal transfer ribbon may occur in
applications requiring high burn settings, high print head pressure, high
speed or high volume.
This contamination will build up on the print head elements, creating a
barrier to the heat transformation required to produce high quality images.
Contaminant build-up occurs gradually and results in poor print quality that
may look like faded print or failed print element(s). This build-up is very
resistant to cleaning with the maintenance wipes and is difficult to remove.
In order to avoid ribbon back-coating and build-up:
• Use thermal transfer ribbons that have been specially cured to provide
back-coat protection for high demand applications. These ribbons,
sometimes referred to as anti-stick ribbons, also dissipate static and
provide more lubrication.
• Follow the recommended print head cleaning procedures.
