• Code: 324.979
• Description: Stapler Near Empty
• Remedy: • Low Staple Sensor On is detected during power On and Interlock Close • Low Staple Sensor On is detected right before the Staple Head Close operation
  Check the Staple Cartridge. If the Staples are NOT low, go to RAP 312.291 (SB).

• Code: 324.980
• Description: Stacker Tray Full Stack
• Remedy: Check any of the following cases: 1. At power-on, Stacker Height SNR detects stacking height and full-stack position. An erroneous detection could be the cause, see RAP 312.212 (SB) for troubleshooting procedure. 2. During height adjustment of stacker tray while printing (lowering) for small-size paper output, the full-stack position is detected. 3. During height adjustment of stacker tray while printing (lowering) for large-size paper output, the half-stack position (full-stack position for large-size paper) is detected. 4. When the half-stack position (full-stack position for large-size paper) has been already detected during printing with small size paper, paper with half-stack limitation (large-size paper) is attempted to be outputted.

• Code: 324.982
• Description: Stacker Lower Safety Warning. During the job, if the height of paper output to stacker tray cannot be adjusted (lowered) within the specified time within three tries, this error will be generated.
• Remedy: Check any of the following causes: 1. Whether an obstacle is under the Stacker Tray. 2. Whether excessive load is applied on the Stacker Tray since the obstacle is in contact with the Stacker Tray. 3. Whether excessive load is applied on the Stacker Tray since the obstacle is in contact with the Stacker Tray. 4. Whether Stacker Motor or its drive parts fail to operate normally. 5. Harness or PWBA failure.

• Code: 324.984
• Description: Booklet Low Staple F. When booklet cover is opened / closed, Booklet Low Staple Switch F detect whether staples are present or not.
• Remedy: If this fault occurs at an unexpected time or if this fault does not occur at expected timing, check the following: 1. Failure of Booklet Low Staple SW F in the Booklet Front Stapler Unit. 2. Whether a staple cartridge is deformed or damaged. 3. Whether a staple cartridge is deformed or damaged. 4. Harness or PWBA failure.

• Code: 324.989
• Description: Booklet Low Staple R. When booklet cover is opened/ closed, Booklet Low Staple Switch F detect whether staples are present or not.
• Remedy: If this fault occurs at an unexpected time or if this fault does not occur at expected timing, check the following: 1. Failure of Booklet Low Staple SW R in the Booklet Rear Stapler Unit. 2. Whether a staple cartridge is deformed or damaged. 3. Whether the storage area of staple cartridge in the Booklet Rear Stapler is deformed or damaged. 4. Harness or PWBA failure.

• Code: 341.310
• Description: IM Logic Fault. The IM software control error was detected.
• Remedy: 1. Turn the power Off and On. 2. Verify the current version and check for any updates. 3. Install the correct version of the IOT firmware. 4. Initialize the IOT NVM (includes writing back the adjustment NVM). If the problem persists, replace the MCU PWB.

• Code: 341.316
• Description: IH Driver Interface Fault. Interface error between the MCU PWB and the IH Driver has occurred (at the IH Driver).
• Remedy: 1. Turn the power Off and check the connection between the IH Driver P/J530 and the MCU PWB P/J414 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • IH Driver PWB • MCU PWB

• Code: 341.317
• Description: MCU IH Interface Fault. Interface error between the MCU PWB and the IH Driver has occurred (at the MCU).
• Remedy: 1. Turn the power Off and check the connection between the MCU PWB P/J414 and the IH Driver P/J530 for open circuit, short circuit, and poor contact. If no problems are found, replace the following parts in sequence: • MCU PWB • IH Driver PWB
