• Remedy:

• Code: F070
• Description: Communication error between System-CPU and Engine-CPU
• Causes: LGC board SYS board LED printer head 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 CN371, CN370 on the LGC board are completely inserted, and the harness is disconnected or open circuited. • Check if the connector pin between the SYS board (connector CN131, CN132) and the LGC board (connector CN371, CN370) is disconnected. • Check if the connectors CN329, CN330, CN331, CN332, CN356, CN357, CN358 and CN359 of the LED printer head are completely inserted, and the harness is disconnected or open circuited. • 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 LED printer head Harness
• Remedy: 1 LED printer head, harness 1-1. Disconnect all the harnesses (flat cable and power supply) of the LED printer heads, and then turn the power ON. Check if the error changes to another service call (CE80 etc.). (CN329, CN330, CN331, CN332, CN356, CN357, CN358, CN359) 1-2. If the error does not change to another service call such as CE80 in step 1-1, go to step 2. If the error changes to another service call, follow the steps below. 1-3. Connect the harnesses of the LED printer head to the LGC board single color at a time, and then turn the power ON to identify the LED printer head in error. Check if F071 occurs. Place the parts causing the error. Check the connectors and harnesses of the color in error. <Harness (flat cable) - LGC board> Y color: CN357 M color: CN358 C color: CN331 K color: CN329 <Harness (power supply) - LGC board> Y color: CN359 M color: CN358 C color: CN332 K color: CN330 <Harness (flat cable) - LED printer head> Y color: CN788 M color: CN790 C color: CN792 K color: CN794 <Harness (power supply) - LED printer head> Y color: CN787 M color: CN789 C color: CN791 K color: CN793 2 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. 3 Board check • Check if the connector CN131, CN132 on the SYS board and the connector CN371, CN370 on the LGC board are completely inserted, and the harness is disconnected or open circuited. • Check if the connector pin between the SYS board (connector CN131, CN132) and the LGC board (connector CN371, CN370) is disconnected. • Check if the connectors CN329, CN330, CN331, CN332, CN356, CN357, CN358 and CN359 of the LED printer head are completely inserted, and the harness is disconnected or open circuited. • Check if the conductor patterns on the LGC board and SYS board are short circuited or open circuited. 4 Harness • Connector check • Harness check

• 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
