Check if the conductor pattern on the LGC board is short- or open-circuited. 5. Replace the registration sensor. 6. Replace the LGC board. YES Check the rollers. Replace them if they are worn out.
  When the paper is fed from any of the lower drawer, PFP or LCF: Open the jam access cover. Is there any paper in front of the upper drawer feed sensor? YES Remove the paper. NO Are the upper/lower drawer feed sensors working? (Perform the input check: 03-[FAX]ON/[3]/[H], /[3]/[G]) NO 1. Check if the connectors of the upper/lower drawer feed sensors are disconnected. 2. Check if the connector CN345 on the LGC board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are open-circuited. 4. Check if the conductor pattern on the LGC board is short- or open-circuited. 5. Replace the upper/lower drawer feed sensors. 6. Replace the LGC board. YES Check the rollers. Replace them if they are worn out.

• Code: EB60
• Description: Paper remaining on the transport path: The multiple feeding of preceding paper caused the misfeeding of upcoming paper (redetection after no jam is detected at [EB50]).
• Remedy: Open the jam access cover. Is there any paper in front of the registration sensor? YES Remove the paper. NO Is the registration sensor working? (Perform the input check: 03-[FAX]ON/[9]/[E]) NO 1. Check if the connector of the registration sensor is disconnected. 2. Check if the connector CN345 on the LGC board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are open-circuited. 4. Check if the conductor pattern on the LGC board is short- or open-circuited. 5. Replace the registration sensor. 6. Replace the LGC board. YES Check the rollers. Replace them if they are worn out.

• Code: F070
• Description: Communication error between System-CPU and Engine- CPU
• Remedy: (1) Check if the harness connecting the SYS board and LGC board is disconnected or open-circuited. (2) Check the version of the system ROM on the SYS board. (3) Check the version of the engine ROM version on the LGC board. (4) Replace the SYS board. (5) Replace the LGC board.

• Code: F090
• Description: SRAM abnormality on the SYS board
• Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When the message “SRAM ERROR DOES IT INITIALIZE?” is displayed on the LCD, press the [INITIALIZE] button. (SRAM is cleared.) (3) Turn the power OFF and then back ON. If the error is not recovered, replace the SYS board.

• Code: F091
• Description: NVRAM abnormality on the SYS board
• Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When the message “NVRAM ERROR DOES IT INITIALIZE?” is displayed on the LCD, press the [INITIALIZE] button. (NVRAM is initialized.) Note: When the NVRAM is initialized, the scanner and image processing related adjustments are also initialized. Readjust them after the NVRAM initialization. (3) Turn the power OFF and then back ON. If the error is not recovered, replace the NVRAM on the SYS board.

• Code: F092
• Description: SRAM and NVRAM abnormality on the SYS board
