Code :

Code: 57.01
Display: 57.01 ERROR
Description: The laser/scanner-unit cooling fan (FM1) has experienced an error.
Remedy: 1. Reconnect the connectors of the laser/ scanner-unit cooling fan (J1916) and the DC controller PCA (J132). 2. Measure the voltage between the connector J132-4 and J132-6 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the laser/scanner-unit cooling fan.

Code: 57.02
Display: 57.02 ERROR
Description: The VOC fan (FM4) has experienced an error.
Remedy: 1. Reconnect the connectors of the VOC fan (J1921) and the DC controller PCA (J103). 2. Measure the voltage between the connector J103-4 and J103-6 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the VOC fan.

Code: 57.03
Display: 57.03 ERROR
Description: The fuser cooling fan (FM2) has experienced an error.
Remedy: 1. Reconnect the connectors of the fuser cooling fan (J1917) and the DC controller PCA (J132). 2. Measure the voltage between the connector J132-7 and J132-9 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the cartridge area cooling fan.

Code: 57.04
Display: 57.04 ERROR
Description: The cartridge area cooling fan (FM3) has experienced an error.
Remedy: 1. Reconnect the connectors of the cartridge area cooling fan (J1915) and the DC controller PCA (J132). 2. Measure the voltage between the connector J132-1 and J132-3 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the cartridge area cooling fan.

Code: 57.05
Display: 57.05 ERROR
Description: The low-voltage power supply cooling fan (FM5) has experienced an error.
Remedy: 1. Reconnect the connectors of the lowvoltage power supply cooling fan (J2), low-voltage power supply (J6) and the DC controller PCA (J102). 2. Measure the voltage between the connector J2-1 and J2-3 on the lowvoltage power supply cooling fan right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the lowvoltage power supply cooling fan.

Code: 57.06
Display: 57.06 ERROR
Description: The cartridge front area cooling fan (FM6) has experienced an error.
Remedy: 1. Reconnect the connectors of the cartridge front area cooling fan (J1934) and the DC controller PCA (J103). 2. Measure the voltage between the connector J103-1 and J103-3 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the cartridge front area cooling fan.

Code: 57.07
Display: 57.07 ERROR
Description: The laser/scanner-unit cooling fan (FM1) has experienced an error.
Remedy: 1. Reconnect the connectors of the laser/ scanner-unit cooling fan (J1916) and the DC controller PCA (J132). 2. Measure the voltage between the connector J132-4 and J132-6 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the laser/scanner-unit cooling fan.

Code: 57.08
Display: 57.08 ERROR
Description: The delivery-unit cooling fan (FM7) has experienced an error.
Remedy: 1. Reconnect the connectors of the delivery-unit cooling fan (J1910) and the DC controller PCA (J103). 2. Measure the voltage between the connector J103-7 and J103-9 on the DC controller PCA right after the product is turned on. If the voltage changes from 0V to approximately 24V, replace the delivery-unit cooling fan.
