Description: PFC board I/F error: Communication error has occurredbetween the PFC board and the equipment.
Remedy: Check the connection. 1. Check if the connector CN113 on the MAIN board is disconnected. 2. Check if the connector CN112 on the switching regulator is disconnected. 3. Check if any of the connectors CN241 and CN242 on the PFC board is disconnected. 4. Check if the relay connector between the ADU board and the PFC board is disconnected. 5. Check if the connector pins are disconnected and the harnesses are open circuited. 6. Check if the conductor patterns on the PFC board and the MAIN board are short circuited or open circuited. 7. Replace the PFC board. 8. Replace the MAIN board.
Code: C94
Description: Firmware update error: An error message appears wheneither of the following Main PC boards is installed to e- STUDIO185/225/245.- The Main PC board for e-STUDIO182- The Main PC board for e-STUDIO165/167/205/207/237
Remedy: Check the MAIN board. A C94 error message appears when either of the following Main PC boards is installed to e-STUDIO195/225/245. • The Main PC board for e-STUDIO182. • The Main PC board for e-STUDIO165/167/205/207/237.
Code: C97
Description: High-voltage transformer abnormality: Leakage of themain charger is detected.
Remedy: Check the High-voltage transformer. 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: C99
Description: PFC microcomputer abnormality
Remedy: Check the PFC board. 1. Check if the error still occurs when the power is turned OFF and then back ON. 2. Check if the conductor patterns on the PFC board are short circuited or open circuited. 3. Replace the PFC board.
Code: CA1
Description: Polygonal motor abnormality: The polygonal motor is notrotating normally.
Remedy: 1 Is the polygonal motor rotating? Yes 1. Check if the conductor pattern on the MAIN board is short circuited or open circuited. 2. Replace the MAIN board. 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.
Remedy: 1 Are the harness open circuited and the connectors disconnected or misconnected between the MAIN board (CN21, CN22) and laser optical unit? Yes 1. Connect the disconnected connectors. 2. Replace the laser optical unit if the harness is open circuited. No 1. Replace the MAIN board. 2. Replace the laser optical unit.
