Code: EF1B
Description: Paper remains at the saddle stitch positioning paper exit sensor for a longer period than specified while being transported in the pushing/folding operation. [MJ-1033]
Causes:
Remedy: Saddle stitch finishing tray sensor (S7) abnormality Measure the voltage on TP65 on the finisher control PC board (FIN). Then check that the measured voltage is 1V or lower when not shielded and within the range of 3.3V±5% when shielded. If the voltage does not fall within the range mentioned, replace the sensor. Faulty cables and connectors Check if the electrical continuity between the connector terminals is normal. If electricity is not conducted, replace the connector. (Finisher control PC board (FIN): CN15) Finisher control PC board (FIN) abnormality If the error still occurs after replacing the sensor and the connector, exchange the finisher control PC board (FIN).

Code: EF1C
Description: Paper is transported in the pushing/folding operation, but does not reach the saddle stitch exit path sensor.
Causes:
Remedy: Saddle stitch finishing tray sensor (S7) abnormality Measure the voltage on TP65 on the finisher control PC board (FIN). Then check that the measured voltage is 1V or lower when not shielded and within the range of 3.3V±5% when shielded. If the voltage does not fall within the range mentioned, replace the sensor. Saddle stitch exit path sensor (S5) abnormality Measure the voltage on TP68 on the finisher control PC board (FIN). Then check that the measured voltage is 1V or lower when not shielded and within the range of 3.3V±5% when shielded. If the voltage does not fall within the range mentioned, replace the sensor. Faulty cables and connectors Check if the electrical continuity between the connector terminals is normal. If electricity is not conducted, replace the connectors. (Finisher control PC board (FIN): CN15, CN16) Finisher control PC board (FIN) abnormality If the error still occurs after replacing the sensors and the connectors, exchange the finisher control PC board (FIN).

Code: EF20
Description: Saddle stacker jam: Transported paper cannot be detected in the stacker. [MJ-1106]
Causes: Stacker paper detection sensor (S30) Saddle controller board
Remedy: Finisher • Is there any paper remaining in the paper transport path in the equipment or the saddle stitch section of the Finisher? Stacker paper detection sensor (S30) • Sensor check • Connector check • Harness check Saddle controller board • Connector check (CN19) • Board check

Code: F090
Description: SRAM abnormality on the SYS board
Causes: SRAM on the SYS board
Remedy: 1. Turn the power OFF and start up the Setting Mode (08). 2. When "SRAM REQUIRES INITIALIZATION" is displayed on the LCD, check the destination and then press the [START] button. If the destination is not correct, key in the correct one and then press the [START] button. 3. After the confirmation message is displayed on the LCD, press the [INTERRUPT] button (to initialize the SRAM). 4. Perform the panel calibration (08-9050). 5. Perform the initialization after the software version upgrade (08-9030). 6. Enter the serial number (08-9601). Be sure that the serial number is the same as that on the identification label attached on the rear cover of the equipment. 7. Initialize the NIC information (08-9083). 8. Turn the power OFF and then start up with the Adjustment mode (05). 9. Perform "Data transfer of characteristic value of scanner" (05-3203). 10.Turn the power OFF and then back ON. If the error is not recovered, replace the SRAM on the SYS board.

Code: F100_0
Description: HDD format error: Operation of HDD key data fails.
Causes:
