Description: Fuser Heater Fan (HTFAN) Error This error indicates a problem with the fuser heater fan (HTFAN).
Remedy: 1 Check Connector Ensure the fuser heater fan motor connector is properly connected to DCN14 on the IOD1 P.W.B. board. Ensure DCN1 on the IOD1 P.W.B. board and 11CN on the main engine (MCTL P.W.B.) board are connected properly. 2 Fuser Heater Fan (HTFAN) Check the voltage between DCN14-10 and DCN14-11. If the voltage is +24V, replace the fuser heater fan (HTFAN). 3 IOD1 P.W.B. Board Check the voltage between DCN1-35 and DCN1-44. If the voltage is +24V, replace the IOD1 P.W.B. board. 4 Main Engine (MCTL P.W.B.) Board If the problem still exists, replace the main engine (MCTL P.W.B.) board.

Description: Erase LED Error This error indicates a problem with the erase lamp.
Remedy: 1 Check Connector Ensure the erase lamp connector is properly connected to DCN7 on the IOD1 board. Ensure DCN1 on the IOD1 board and 11CN on the main engine (MCTL P.W.B.) board are connected. 2 Erase Lamp (LED P.W.B.) Check for voltage between DCN7-11 and DCN2-25 on the IOD1 board. • If the voltage drops to less than +24V, replace the erase lamp (LED P.W.B.). 3 • IOD1 P.W.B. Board • Main Engine (MCTL P.W.B.) Board Check for voltage between DCN1-27 and DCN1-44 on the IOD2 P.W.B. board. • If the voltage jumps to +24V, replace the IOD1 P.W.B. board. If the problem still exists, replace the main engine (MCTL P.W.B.) board.

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

Description: Fuser Themistor Error
Remedy: 1 Fuser Unit Ensure the fuser is properly installed. If the fuser is damaged, replace the fuser unit. Note: The fuser unit is a customer order supply. 2 Fuser Connector Check the fuser connector for damage and replace, if necessary. 3 • Fuser Unit • IOD1 P.W.B. Board • Main Engine (MCTL P.W.B.) Board Ensure the fuser connector, FUCN, to the main engine (MCTL P.W.B.) board is properly connected. If the problem still exists, replace the following parts in the order given until the error is cleared. • Fuser unit • IOD1 P.W.B. board • Main engine (MCTL P.W.B.) board
