Physical damage to the thermistor’s wire harness or a loose connector (usually CNxxx on the fuser or controller board) creates an intermittent signal.
The Ricoh SC569-00 is a Service Code ("SC") indicating a . This error occurs when the machine’s fuser unit fails to properly engage or disengage the pressure roller against the hot roller, preventing the machine from finishing a print job and creating a "dead" copier scenario. What is the SC569-00 Error?
The Power Supply Unit (PSU) or the AC Drive Board generates the zero-cross signal. Fluctuating input voltage (dirty AC power, loose wall outlet, overloaded circuit) or failing capacitors on the PSU can corrupt this signal.
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. sc569-00 ricoh
The system operates as follows:
Thoroughly clean the bearings and matching shafts using isopropyl alcohol and clean rags to remove all degraded factory grease.
Panicked, John tried turning the printer off and on, but the error persisted. He checked the printer's manual and online forums, but the information about the SC569-00 error code was limited. Physical damage to the thermistor’s wire harness or
This article provides a deep dive into what the SC569-00 error means, its common causes, and step-by-step solutions to get your Ricoh device back online. What is the Ricoh SC569-00 Error?
Dust or toner buildup on the "U-shaped" HP sensor can prevent it from detecting the actuator.
: Turn the machine off using the main power switch, wait for about 60 seconds, and turn it back on. Check Paper Compatibility : Ensure you are using standard office paper What is the SC569-00 Error
Failure to do this may cause the printer to falsely re-trigger SC569-00 because the old fuser’s error log remains in memory.
: Mechanical resistance or debris can prevent the camshaft from rotating smoothly.
A: If the error returns after replacing both the sensor and motor, focus on the mechanical drive train and connections. Re-check the fusing unit's connector to the machine and look for a failing one-way gear in the fuser drive unit. In some cases, the encoder plate can be misaligned; ensure it is in the correct home position.
