Developing stirring motor (Y) error
Lock signal of Developing stirring motor (Y) (M26)cannot
be detected for the specified period of time after first
detection
• Connector disconnected, breaking (shorting)
• Failure of the developing assembly (Sleeve
overloaded)
• Failure of the DC controller interface PCB (Fuse (FU7
burns))
