118C938489 (also marked F118C938489) is a brand-new high-precision paper transport stepper motor, specially produced for FUJI Frontier 340, 350, 355, 370, 375 digital minilabs. As the core power component of the paper feeding and transmission system, it provides stable step drive power for accurate photo paper conveying and positioning. Aging or damaged motors will cause paper feeding jitter, paper jam, unstable paper length, motor abnormal noise and machine error alarms. Every motor is fully tested before shipment, direct plug-and-play replacement to restore stable paper-transport operation and reduce lab downtime.
