This appears to be a fan disconnection or malfunction.
It will need to be serviced by an engineer who knows the internals and can open the printer without damage.
1 Verify that the connector J65 on the dc controller is firmly seated. 2 Listen for the fan to operate while the MFP is initializing. 3 If the fan does not operate during the initialization sequence, replace it. See Main fan (FN101) and reversing-unit fan (FN103)
