Sc569-00 Ricoh -

The SC569-00 error on Ricoh printers typically indicates a fusing unit pressure release motor error. This happens when the machine cannot detect the movement of the pressure release mechanism, which is critical for the fuser to engage or disengage correctly during the heating and cooling cycles. Potential Causes

Fuser Unit Pressure Release Motor: The motor responsible for moving the pressure roller might be defective or stalled.

Pressure Release Sensor: The sensor (often U-shaped) that detects the position of the pressure mechanism may be dirty, disconnected, or failing due to high heat exposure.

Mechanical Obstruction: A paper jam or physical blockage in the fuser area preventing the gears or rollers from moving.

Connection Issue: Poor contact between the fuser unit connectors and the machine's internal frame. Troubleshooting Steps

Inspect for Jams: Turn off the power and check the fuser and paper exit areas for any scraps of paper that might be blocking the mechanism.

Clean the Sensor: If you are comfortable opening the unit, check the pressure release sensor for dust or toner buildup.

Reseat the Fuser: Pull out the fuser unit and push it back in firmly to ensure all electrical pins are properly seated. sc569-00 ricoh

Perform an SC Reset: Sometimes the error is "locked" even after the mechanical issue is cleared. You can try a reset through the Service Mode:

Enter Service Mode (the procedure varies by model, often involves pressing Clear Modes followed by 1-0-7 and holding Clear/Stop).

Navigate to System SP > Mode 5 > Submenu 5810 (SC Reset) and tap it. Restart the machine completely.

If the error persists after a reset, the pressure release motor or its associated sensor likely requires a hardware replacement.

Troubleshooting Ricoh Error Code SC569-00: A Quick Guide If your Ricoh multifunction printer has ground to a halt with Error Code SC569-00, you’re dealing with a Fusing Pressure Release Motor Error. This service code appears when the machine's control board fails to detect the pressure release sensor's signal within a specific timeframe after the motor starts.

In simpler terms: the machine is struggling to engage or disengage the rollers in the fuser unit, which is critical for bonding toner to your paper. Common Causes

Sensor Failure: The pressure release sensor (often U-shaped) may be dirty, displaced, or faulty due to high heat exposure. The SC569-00 error on Ricoh printers typically indicates

Motor Malfunction: The motor responsible for moving the pressure rollers is defective or physically obstructed.

Mechanical Jam: Loose paper scraps or toner buildup can prevent the gears from turning.

Connection Issues: Loose wiring or poor contact between the fuser unit and the main body of the copier. Steps to Resolve SC569-00 1. Perform a Hard Reset

Sometimes the error is a temporary glitch. Turn off the main power switch, unplug the machine for at least 60 seconds, and then restart it. If the code persists, move to the next steps. 2. Check for Obstructions

Open the side panel and carefully inspect the fuser area. Look for any small scraps of paper or debris caught in the gears or near the pressure release motor. Use a can of compressed air to clear away dust or loose toner that might be blocking the sensor's "eye." 3. Inspect the Fuser Connector

Pull the fuser unit out (be careful, it may be hot) and inspect the rear connectors. Ensure no pins are bent and that the unit "clicks" firmly into place when re-inserted. 4. Reset the SC Code (Service Mode)

If you have cleared a physical jam but the error remains, you may need to reset the system through the Service Program (SP) mode. Phillips screwdriver (#1, #2) Needle-nose pliers Canned air

Note: This typically requires a technician. Entering service mode incorrectly can affect machine performance. When to Call a Professional

If the sensor or motor has physically failed, parts will need to be replaced. You can find authorized service providers through the Ricoh Support page or by contacting local retailers like Copier Liquidation Center for technical guidance.

Canned air or vacuum
Small brush
(Optional) Multimeter, known-good finisher

Step 3: Sensor Check (Input Mode)

Enter SP mode (Stop → 1 → 0 → 7 → Stop → Start) or use the Finisher Input Check in SP5803.

Locate the alignment fence home sensor input (check service manual for bit number, typically like "Finisher HP Sensor" or "Align HP").

Manually move fence to home position → input should toggle.
If it does not change → sensor or harness problem.
If it always shows "1" or "0" → sensor stuck.

5. Defective Power Supply Unit (PSU)

Less common but serious: The PSU’s zero-cross detection circuit fails. In this case, even a brand-new fuser will trigger SC569-00 immediately upon installation.
