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 in the test mode: 03-[FAX]ON/[2]/[A]) NO 1. Check if the connector of the registration sensor is disconnected. 2. Check if the connector CN318 on the LGC board is disconnected. 3. Check if the connector pins are disconnected and the harnesses are opencircuited. 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 (CN117) and LGC board (CN321) 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 [INITIALIZE]. (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 [INITIALIZE]. (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
Remedy: (1) Turn the power OFF and start up the Setting Mode (08). (2) When the message "NVRAM/SRAM ERROR DOES IT INITIALIZE?" is displayed on the LCD, press [INITIALIZE]. (SRAM is cleared and 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: F100
Description: HDD format error: HDD cannot be initialized normally.
Remedy: (1) Check if the HDD is mounted. (2) Check if the specified HDD is mounted. (3) Check if the connector pins of the HDD are bent. (4) Check if the power supply connector is disconnected. (5) Check if the connector J111 on the SYS board is disconnected. (6) Replace the harness. (7) Initialize the HDD. (Key in “2” at 08-690.) (8) Replace the HDD. (9) Replace the SYS board.
Code: F101
Description: HDD unmounted: Connection of HDD cannot be detected.
Remedy: (1) Check if the connectors of the HDD are disconnected. (2) Check if the connector pins are disconnected or the wires of harnesses are broken. (3) Perform the bad sector check (08-694). If the check result is OK, recover the data in the HDD. If the check result is failed, replace the HDD. (4) Replace the SYS board.
Code: F102
Description: HDD start error: HDD cannot become ‘Ready’ state.
Remedy: (1) Check if the connectors of the HDD are disconnected. (2) Check if the connector pins are disconnected or the wires of harnesses are broken. (3) Perform the bad sector check (08-694). If the check result is OK, recover the data in the HDD. If the check result is failed, replace the HDD. (4) Replace the SYS board.
