• Code: F070
• Description: Communication error between System-CPU and Engine-CPU
• Remedy: (1) Check if the connector CN104 on the SYS board and CN130, CN131, CN134 on the SYSIF board is disconnected. (2) Check if the connector CN10 on the SLG board is disconnected. (3) Check if the harness connecting the SYSIF board and SLG board is disconnected or open circuited. (4) Check if the harness connecting the SYSIF board and LGC board is disconnected or open circuited. (5) Check if the connection of the SYS board (CN104) and SYSIF board (CN130) is open circuited. (6) If the SYS board has been replaced, check if the jumper pin setting on the SYS board is correct. (The jumper pin should be inserted between pin 2 and 3 of CN103 and CN115.) (7) Check the version of the system ROM on the SYS board. (8) Check the version of the engine ROM version on the LGC board. (9) Check the version of the scanner ROM version on the SLG board. (10) Replace the SYS board. (11) Replace the SLG board. (12) Replace the LGC board. (13) Replace the SYSIF board.

• Code: F090
• Description: SRAM abnormality on SYS board
• Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When “SRAM ERROR DOES IT INITIALIZE” 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 (08-692). (5) Perform the initialization at the software version upgrade (08-947). (6) Enter the serial number (08-995). Be sure that the serial number is the same as that on the identification label attached on the rear cover of the equipment. Note: The MAC address of the equipment is generated based on this serial number. Entering the incorrect serial number may result in an inability to access the network due to an invalid MAC address. (7) Initialize the NIC information (08-693). (8) Turn the power OFF and then start up with the Adjustment mode (05). (9) Turn the power OFF and then back ON. If the error is not recovered, replace the SRAM on the SYS board.
