• Code: EF20
• Description: [MJ-1110] Stacker jam in the saddle stitch unit
• Causes: Stacker paper detection sensor (S30) Saddle control PC board (SDL)
• Remedy: Paper • 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 (CN3) • Harness check Saddle control PC board (SDL) • Connector check (CN3) • Board check

• Code: F070
• Description: Communication error between System-CPU and Engine-CPU
• Causes: LGC board SYS board Harness
• Remedy: Error code • Turn the power OFF and then back ON using the main power switch, and then check if the error code changes to another one. • If it changes to another one, follow the procedure for the changed error code. Check firmware version • Check the version of the system firmware on the SYS board. • Check the version of the engine firmware on the LGC board. Board check • Check if the connector (CN131, CN132) on the SYS board and the connector (CN330, CN329) on the LGC board are completely inserted. • Check if the connector pin between the SYS board connectors (CN131, CN132) and the LGC board connectors (CN330, CN329) is disconnected. • Check if the connector CN314 on the LGC board and the connector CN512 on the PS-ACC are completely inserted. • Check if the conductor patterns on the LGC board and SYS board are short circuited or open circuited Harness • Connector check • Harness check

• Code: F071
• Description: Communication initialization error between System-CPU and Engine-CPU
• Causes: LGC board SYS board Harness
• Remedy: Error code • Turn the power OFF and then back ON using the main power switch, and then check if the error code changes to another one. • If it changes to another one, follow the procedure for the changed error code. Check firmware version • Check the version of the system firmware on the SYS board. • Check the version of the engine firmware on the LGC board. Board check • Check if the connector (CN131, CN132) on the SYS board and the connector (CN330, CN329) on the LGC board are completely inserted. • Check if the connector pin between the SYS board connectors (CN131, CN132) and the LGC board connectors (CN330, CN329) is disconnected. • Check if the connector CN314 on the LGC board and the connector CN512 on the PS-ACC are completely inserted. • Check if the conductor patterns on the LGC board and SYS board are short circuited or open circuited Harness • Connector check • Harness check LGC board • 25/30/35 ppm: Measure the voltage on TP33 on the LGC board. Then check that the measured voltage is 3.3V. If the voltage does not output, replace the LGC board. • 45/50 ppm: Measure the voltage on TP18 on the LGC board. Then check that the measured voltage is 3.3V. If the voltage does not output, replace the LGC board.

• Code: F090
• Description: SRAM abnormality on the SYS board
• Causes: SRAM SYS board
• Remedy: SRAM 1. Check that the SRAM is installed properly. 2. Shut down the equipment. 3. Perform [FS-08]. 4. Press [CLASSIC]. 5. When “SRAM REQUIRES INITIALIZATION” appears on the LCD screen, confirm the destination and press the [START] button. If the destination is incorrect, enter the number for the correct one and press the [START] button. 6. When the confirmation message appears on the LCD screen, press [INITIALIZE]. (SRAM initialization starts.) 7. Enter the serial number of the equipment correctly. (FS-08- 9601) 8. Initialize the NIC information. (FS-08-9083) 9. Shut down the equipment. 10.Perform [FS-05]. 11.Press [CLASSIC]. 12.Perform “Data transfer of characteristic value of scanner”. (FS-05-3203, FS-05-3240) 13.By using the [4] [TEST PRINT] test pattern, perform “Automatic gamma adjustment” <PPC>. (FS-05-7869) 14.By using the [70] [TEST PRINT] test pattern, perform “Automatic gamma adjustment” <PRT>. (FS-05-8008) 15.Reboot the equipment. 16.If the error still occurs, replace the SRAM. SYS board Board check

• Code: F350
• Description: SYS board abnormality
• Causes: SYS board
• Remedy: SYS board Board check Combination of the firmware version • Check the combination of the firmware version of the system firmware, system software, engine firmware, and scanner firmware. • Reinstall the firmware of correct combination.
