• Remedy: 1. Check the product power source. Make sure that the power source meets product requirements. NOTE: If the power source does not meet the power frequency requirements of 43 to 67Hz, the fuser temperature control does not work correctly and causes this error. 2. If possible, connect the product to an outlet where another product is functioning to verify the power connection. 3. Check and reconnect the connectors (J206 and J219) on the DC controller PCA. 4. If the error persists, replace the cable guide assembly, LVPS, and then the DC controller if necessary.
