Several underlying mechanical and electrical issues can trigger this fault code: While offering distinct advantages in print quality and
Xerox solid ink printers represent a unique segment of the printing market, utilizing solid polymer blocks (ink sticks) rather than traditional toner powder or liquid ink. While offering distinct advantages in print quality and environmental impact, these machines rely on complex thermal management systems.
Inspect the gold electrical contacts on the back of each cartridge for dirt or toner buildup. Clean them gently with a dry, lint-free cloth.
Verify that the connection between the YMC link sensor ( P/J108 ) and the Drive PWB ( P/J407 ) is seated perfectly.
