Description: Thermistor abnormality during printing: Abnormality of the thermistor is detected during printing
Remedy: 1. Check the thermistors (1) Check if the connectors are disconnected. (2) Check if the center, side and edge thermistors are in contact with the surface of the fuser roller properly? (3) Check if the harnesses of the center, side and edge thermistors are open circuited. 2. Check the heater (1) Check if the heater is broken. (2) Check if the connector of the heater is disconnected. (3) Check if the thermostat is blown. 3. Check the MAIN board (1) Check if the connectors CN17 are disconnected. (2) Check if the conductor pattern on the MAIN board is short circuited or open circuited. (3) Replace the MAIN board. 4. Check the switching regulator (1) Check if the connectors CN108 are disconnected. 5. Clear the status counter Change the current status counter value (08-400) “5”, “7” or “9” to “0” for [C44], taking the same procedure as that for [C41]. * The status counter value is as follows in the following cases. Change them to “0” respectively. • The error occurred during warming-up: “5” • The error occurred after the equipment has become ready: “7” • The temperature detected by the center thermistor is 230°C or higher: “9” • The temperature detected by the side thermistor is 230°C or higher: “9” • The temperature detected by the edge thermistor is 230°C or higher: “9” only during printing.

Description: High-voltage transformer abnormality: Leakage of the main charger is detected.
Remedy: (1) Is the main charger installed securely? (2) Check if the spring of high-voltage supply contact point is deformed. (3) Check if the needle electrode is broken or the main charger grid is deformed. (4) Check if any foreign matters is on the needle electrode or the main charger grid. (5) Is the transfer/separation charger installed securely? (6) Check if the transfer/separation charger wire is broken or unhooked. (7) Check if any foreign matter is on the transfer/separation charger wire.
Code: CA1
Description: Polygonal motor abnormality: The polygonal motor is not rotating normally
Remedy: Is the polygonal motor rotating? NO 1) Check if the connector of the harness is disconnected between MAIN board (CN24) and the laser optical unit. 2) Check if the harness is open circuited and the connector pin is disconnected. 3) Check if the conductor pattern on the MAIN board is short circuited or open circuited. 4) Replace the laser optical unit. 5) Replace the MAIN board. YES 1) Check if the conductor pattern on the MAIN board is short circuited or open circuited. 2) Replace the MAIN board.
Remedy: Are the harness open circuited and the connectors disconnected or misconnected between the MAIN board (CN21, CN22) and laser optical unit? YES Replace the harness. Connect the disconnected connectors. NO 1) Replace the MAIN board. 2) Replace the laser optical unit.
