• Code: 324.917
• Description: Stacker Tray Staple Set Over Limit
• Remedy: During detection of staple sheet count, if over 50 sheets are detected (Stapling limit), this error will be generated. If this chain link code is generated in error, check the following: • Check for a defective stacker no paper sensor. See Stacker Tray Control. Execute dc330 Component Control [012-262], Stacker No Paper Sensor and repair or replace as necessary. • Defective wiring, Check the continuity of the wiring as shown in PWBS Communication from J8989 on the Finisher PWB to P/J590 on the MD PWB. • Defective Finisher PWB.

• Code: 324.926
• Description: Punch Box Set Fail. Punch Box Set Sensor detected Punch Box to be missing.
• Remedy: • Ensure that the Punch Box is present and installed properly.
  Enter dc330 Component Control [012-275], Punch Box Set Sensor (PL 23.5 Item 5). Select Start. Remove and insert the Punch Box manually. The display changes Y↓ N→Select Stop. Check continuity between the Punch Box Set Sensor J8866, J8863, and the Finisher PWB P8987. The continuity check is OK. Y↓ N→Repair the open circuit or short circuit. Replace the Punch Box Set Sensor (PL 23.5 Item 5). If the problem continues, replace the Finisher PWB. Check the Punch Box Set Sensor Actuator and Punch Box Guide for deformation. The Punch Box can be removed and inserted properly. Y↓ N→Repair or replace the Punch Box (PL 23.2 Item 11). Select Stop. If the problem continues, replace the Finisher PWB.

• Code: 324.928
• Description: Scratch Sheet Compile. Paper was detected that was either out of spec, in poor condition (wrinkled, curled) and was ejected to the compiler. NOTE: This Code is an operation message. If this fail code is frequently declared, perform the procedure below.
• Remedy: • Check that the Top Cover can be opened and closed. • Power Off/On.
  Check the specifications of paper. The paper is in specification. Y↓ N→Replace the paper with new paper that is in the specification. Check the condition of the paper. The paper is in normal condition without any problem that causes the paper to be bent (dog eared) or jam. Y↓ N→Resolve any problem that causes the paper to be bent or caught. Check for a Fault Code. Another Fault Code is displayed. Y↓ N→If the problem continues, replace the Finisher PWB. Go to the appropriate Fault Code.

• Code: 324.963
• Description: Punch Dust Box Full
• Remedy: Empty the Punch Box (PL 23.2 Item 11) and re-insert. If the fault remains, check the circuit of the Punch Box Set Sensor (Punch Control).

• Code: 324.976
• Description: Staple NG
• Remedy: 1. Lack of stapler penetration force when media outside the spec is used. 2. Staple jam (staple remains in the staple cartridge). 3. Whether foreign matter is around the Stapler in the Compile Tray. 4. Stapler unit failure. 5. Harness or PWBA failure. NOTE: When the penetration force is not enough for the media desired, the maximum number of sheets in a set to be stapled can be reduced with NVM. (763-630)

• Code: 324.977
• Description: Stapler Feed Ready Fail. After a new cartridge is inserted, the stapler will make 13 attempts to feed staples before generating this error.
• Remedy: Check the following: 1. Whether a staple cartridge is mis-installed. 2. Stapler pin jam (staple pin remains in the staple cartridge). 3. Whether foreign matter is in the transport area of staple pins in the Stapler Unit. 4. Whether a staple cartridge is deformed or damaged. 5. Stapler Unit failure. 6. Harness or PWBA failure.
