Description: FAX-BOX skating trouble The FAX-BOX PWB is not one for the AR-FX12. (FAX detection) The FAX-BOX MODEM controller is not one for the AR-FX12.
Causes: The FAX-BOX Modem controller PWB information (hard detection) is not for the AR-FX12. (The Modem controller PWB for the AR-FX5 or the AR-FX6 is used.)
Remedy: Check the FAX-BOX modem controller PWB. Replace it with a modem controller PWB for the AR-FX12.
Code: F6-98
Description: Combination error of the FAX-BOX destination information and the machine destination information Combination error of the FAX-BOX destination information and the machine destination information
Causes: Because of improper combination between the destination information stored in the EEPROM on the FAXBOX PWB and that of the machine (set with SIM 26-6).
Remedy: Check the destination of the FAX-BOX. Check the machine destination with SIM 26-6. Use a proper combination of the machine and the FAX-BOX.
Remedy: When replacing the EEPROM, use SIM66-4/5 (Signal send level) and SIM66-14/15/16 (Dial test) for adjustment. However, note that all the soft switches are reset to the initial values. No need to adjust when the PWB is replaced.
Code: H2
Description: Thermistor open Fusing unit not installed Thermistor is open. (An input voltage of 2.92V or above is detected.) Fusing unit not installed
Causes: Thermistor trouble Control PWB trouble Fusing section connector disconnection AC power trouble Fusing unit not installed
Remedy: Check harnesses and connectors from the thermistor to the control PWB. Use SIM14 to clear the self diag display.
Code: H3
Description: Fusing section high temperature trouble The fusing temperature exceeds 242°C. (An input voltage of 0.27V or above is detected.) Fusing temperature control is started, and 242°C is detected three or more times continuously in sampling in the specified interval. (Every 300msec)
Causes: Thermistor trouble Control PWB trouble Fusing section connector disconnection AC power trouble
Remedy: Use SIM5-2 to check the heater lamp Blinking operation. If the heater lamp blinks normally: Check the thermistor and its harness. Check the thermistor input circuit in the control PWB. If the heater lamp keep lighting: Check the AC PWB and the lamp control circuit in the control PWB. Use SIM14 to cancel the trouble
Code: H4
Description: Fusing section low temperature trouble The set temperature is not reached within the specified time (3 min) after turning on the power relay, or the temperature does not reach 80°C within 80 sec. When the heater lamp is not turned off in the specified time (3 min) from starting warm-up, or the temperature does not reach 80°C within 80 sec. After completion of warm-up operation, a temperature 50°C lower than the temperature control level is detected 5 times continuously in sampling in the specified interval. (every 300msec)
Causes: Thermistor trouble Heater lamp trouble Control PWB trouble Thermostat trouble AC power trouble Interlock switch trouble
Remedy: Use SIM5-2 to check the heater lamp Blinking operation. If the heater lamp blinks normally: Check the thermistor and its harness. Check the thermistor input circuit in the control PWB. If the heater lamp does not light: Check for heater lamp disconnection and thermostat disconnection. Check the interlock switch. Check the AC PWB and the lamp control circuit in the control PWB. Use SIM14 to cancel the trouble.
