• Code: C1300
• Description: Polygon Motor malfunction
  Startup failure • A LOW Polygon Motor (M2) Lock signal is not detected within a given period of time that begins 1 sec. after the Polygon Motor has started turning. Lock signal fault: Unstable after the first Lock signal has been detected • For a period of 1 sec. after the first LOW Polygon Motor (M2) Lock signal (first Lock) has been detected, the next LOW Polygon Motor Lock signal is not detected. Lock signal fault: Lock signal out-of-timing • A LOW Polygon Motor (M2) Lock signal is not detected for a continuous given period of time while the rotation of the Polygon Motor remains stabilized. Faulty Lock signal • A LOW Polygon Motor (M2) Lock signal is detected for a given period of time or more when the Polygon Motor remains deenergized.
• Remedy: 1 C1300/C13F0 reappears when the copier is turned OFF and ON again. <Check Procedure> Turn OFF and ON the Power Switch to check to see if C1300/C13F0 reappears. YES • Go to step 2. 2 Polygon Motor (M2) connector PJ13A is loose. YES • Reconnect connector PJ13A. 3 The following voltage is supplied to the Polygon Motor (M2). <Check Procedure> Check voltage across a Master Board (copier: PWB-A) and GND when the Start key is pressed. • Voltage across PJ13A-3 and GND DC5 V while Polygon Motor (M2) is in standby state DC0 V when Polygon Motor (M2) is energized YES • Change PH Unit. NO • Change Master Board (copier: PWB-A).

• Code: C13F0
• Description: Faulty HSYNC
  Laser scanning system malfunction • The SOS Sensor does not detect a rising edge of SOS within a given period of time after the Polygon Motor (M2) has started turning and a laser output has been started. • The SOS Sensor detects no rising edges of SOS while VIA (image area control) is ON.
• Remedy: 1 C1300/C13F0 reappears when the copier is turned OFF and ON again. <Check Procedure> Turn OFF and ON the Power Switch to check to see if C1300/C13F0 reappears. YES • Go to step 2. 2 Polygon Motor (M2) connector PJ13A is loose. YES • Reconnect connector PJ13A. 3 The following voltage is supplied to the Polygon Motor (M2). <Check Procedure> Check voltage across a Master Board (copier: PWB-A) and GND when the Start key is pressed. • Voltage across PJ13A-3 and GND DC5 V while Polygon Motor (M2) is in standby state DC0 V when Polygon Motor (M2) is energized YES • Change PH Unit. NO • Change Master Board (copier: PWB-A).

• Code: C1468
• Description: Faulty EEPROM
  EEPROM fault • Data cannot be written in EEPROM. • Data stored in EEPROM is wrong.
• Remedy: 1 C1468 reappears when the copier is turned OFF and ON again. <Check Procedure> Turn OFF and ON the Power Switch to check to see if C1468 reappears. YES • Go to step 2. 2 Memory (U29) on Control Board (copier: PWB-C) is loose. YES • Reinstall memory (U29). NO • Change Control Board (copier: PWB-C).

• Code: C14A3
• Description: IR fluorescent lamp fault
  The Exposure Lamp (LA2) of the Scanner fails to turn ON. • The intensity of the Exposure Lamp is a predetermined value or less during shading and re-shading.
• Remedy: 1 Exposure Lamp turns ON when the Power Switch is turned ON. NO • Go to step 3. 2 Exposure Lamp is abnormally lit (flickers or abnormally dark) when the Power Switch is turned ON. NO • Go to step 4. 3 Inverter Board (copier: PU2) connector is loose. YES • Reconnect. NO • Change Exposure Lamp (LA2). 4 CCD Board (copier: PWB-J) connector is loose. YES • Reconnect. 5 The following voltage is supplied from the Control Board (copier: PWB-C). <Check Procedure> Check voltage across a Control Board (copier: PWB-C) pin and GND when the Power Switch is turned ON. • Voltage across JP16C-4 and GND DC24 V when Exposure Lamp (LA2) is OFF DC0 V when Exposure Lamp (LA2) is ON YES • Change Inverter Board (PU2). NO • Change Control Board (copier: PWB-C).
