• Code: 922
• Description: Fuser Temperature Error
  These errors indicate a fuser temperature error.
• Remedy: 1 Fuser Unit Check for dirt or any damage to the fuser unit and replace, if necessary. Turn the machine on and determine whether the fuser heater is On. If the heater lamp is On, check for the correct input line voltage. If the line voltage is correct and the error still exists, replace the fuser unit. Note: The fuser unit is a customer order supply.
  2 • Fuser Low Voltage Power Supply (LVPS) • Main Engine (MCTL P.W.B.) Board Turn the machine On and determine whether the fuser is On. If the heater lamp is Off, check the following: • Ensure the fuser is installed properly. • Ensure the fuser connector is not damaged and replace, if necessary. If the problem still exists, replace the following parts in the order given until the error is cleared. • Fuser unit Note: The fuser unit is a customer order supply. • Low voltage power supply (LVPS) • Main engine (MCTL P.W.B.) board

• Code: 934
• Description: Printhead Power Error
  Ensure the printhead connector, LCN1, is properly connected to LCN on the main engine (MCTL P.W.B.) board. If the problem still exists, replace the low voltage power supply (LVPS).
• Remedy: Ensure the printhead connector, LCN1, is properly connected to LCN on the main engine (MCTL P.W.B.) board. If the problem still exists, replace the low voltage power supply (LVPS).

• Code: 939
• Description: RIP to Engine Communication Error
  Indicates that the RIP controller board and the main engine (MCTL P.W.B.) board cannot communicate. The RIP board, main engine (MCTL P.W.B.) board or cabling may be defective. Check each board for correct installation and be sure all grounds are secure. If no problem exists, replace the following FRUs in the order shown: • Main engine (MCTL P.W.B.) board • RIP controller board
