Description
Drive circuit fault
Recommended action
1. Remove and reinstall the fuser. Make sure that it is seated correctly.
2. Check the printer power source. Make sure that the power source meets printer requirements. Make sure
that the printer is the only device using the circuit.
NOTE: If the printer does not meet the power requirement of 43 to 67Hz frequency, the fuser
temperature control does not work properly and this will cause the malfunction.
3. Reconnect the connector (J128) on the DC controller PCA.
4. Replace the fuser power supply assembly.
