Sc569-00 — Ricoh

When any single step in this chain fails, the main board cannot verify that the mechanism is working. After three consecutive failures, the printer will throw the SC569-00 code.

Loose or poor contact in the connector between the fuser unit and the machine's internal frame. Troubleshooting Steps

Enter Service Mode (typically by pressing → 107 → hold Stop/Clear for 3+ seconds). Navigate to System SP . Find and execute SP 5810 (SC Reset) . Restart the machine to complete the process.

The code appears when the printer's control system detects a malfunction in this pressure release mechanism. Specifically, the machine tries to activate or deactivate the pressure, but a sensor fails to confirm the action three times in a row. sc569-00 ricoh

Turn on the machine and wait for the error message screen to load. Tap the physical or digital button. Type the numerical sequence 806182 quickly on the keypad.

According to Ricoh technical documentation, the code is defined as a: Paper Exit / Pressure Release Motor Error Detection

If a new fuser still triggers SC569-00, the issue lies in the AC Drive Board or PSU. Check for:

(typically 20lb/75gsm) while troubleshooting to rule out media-related stress on the motor. Service Mode Reset

Once the screen reports "Completed," cycle the main power switch off and back on to reboot the system. Technical Summary for Engineers Technical Check Primary Resolution Test continuity and check for clean optical lanes. Wipe clean or replace. Actuator Gear Look for broken or worn half-moon gear teeth. Replace the gear set. Release Motor Check winding resistance and verify DC power delivery. Replace the motor unit. Drawer Connector Inspect for bent pins behind the fuser chassis. Re-seat or straighten pins. Restart the machine to complete the process

Common technical causes for this error often start with the fuser unit itself. Over time, the internal gears or the cam mechanism that facilitates pressure release can become worn, stripped, or clogged with built-up toner dust and paper debris. If the mechanical resistance becomes too great for the motor to overcome, the system will shut down and display the SC569-00 code as a protective measure. Additionally, a faulty pressure release sensor—which tells the printer's main board whether the rollers are "open" or "closed"—can be the culprit. if the sensor fails to send the correct signal, the printer assumes the motor has failed, even if it is physically moving.
