SYMPTOM
False E54 – Fusing Error
1. At power-up
E54 is indicated after the warm-up, usually seconds after the fusing lamp has turned off at
185°C. This occurs only in the machines set up to use the fusing phase control mode.
2. Other Possible Occurrences
E54 may be also indicated in any mode – warm-up, stand-by, and copying. This occurs
regardless of the fusing control mode.
CAUSE
Software bug
SOLUTION
1. Install the E version ROM.(A2025108E for Bantam and A2035108E for Bantam R)
2. If the ROM is not immediately available, select the ON/OFF control mode because
case #2 listed hardly ever occurs.
Note: Do not select the phase control mode unless needed.
