Problem

Factories lacked enough highly skilled personnel. Experienced technicians held equipment-maintenance knowledge that had not always been put into words.

Approach

TOPPAN's AI development team built a system trained on experienced technicians' maintenance knowledge and previously undocumented expertise. The system supported work involving equipment faults and maintenance. By February 2025, TOPPAN reported deployment at 6 factories.
