Open the right-side access door and slide out the fusing assembly.
Turn off the printer, unplug it, and allow the fuser unit to cool completely. Slide the fuser unit out of the machine.
Some components are more complex and are best handled by a certified technician.
The primary function of the fusing unit is to press a heated roller against a pressure roller. The SC569-00 error occurs when the "Paper Exit/Pressure Release Motor" or its associated sensor fails to confirm the movement of these rollers. The causes can be broadly broken down into three categories: sc569-00 ricoh
Poor contact between the fuser unit connectors and the machine's internal frame. Troubleshooting Steps
For a first-time occurrence, users may attempt a soft reset by powering the machine down, unplugging it for 60 seconds, and restarting. If the error persists, technical intervention is required: Service Mode Reset
While it can happen to any enterprise unit, this error is heavily documented in high-performance Ricoh Aficio , MP, and MP C series, including: MP C2003, MP C3004ex, MP C4503, MP C6003 Open the right-side access door and slide out
Two sub-cases:
A paper jam or physical blockage in the fuser area preventing the gears or rollers from moving.
The is a critical system fault that signals a fusing pressure release motor error or a depressurizing error detection failure . This hardware-level Service Call (SC) code blocks the copier from printing or copying to prevent permanent damage to the internal machinery. It commonly impacts multi-function printers (MFPs) like the Ricoh MP C3003, C3503, C4503, C6003, C3004, C3504, and C4504 series . Some components are more complex and are best
| Category | Specific Component | Common Failure Mode | | :--- | :--- | :--- | | | Gears & Linkages | A crack, break, or excessive friction can prevent the motor from moving the mechanical linkage to its correct position. | | Motor & Electrical | Paper Exit/Pressure Release Motor | The motor itself may be faulty, burnt out, or experiencing an electrical overload that causes it to lock up. | | Sensor Issues | Pressure Release HP Sensor | A defective sensor, a broken actuator, or a loose connection can prevent the main board from receiving the signal confirming the mechanism is at its Home Position (HP). |
: The Paper Exit/Pressure Release Motor may be failing or disconnected. Step-by-Step Troubleshooting and Repair Follow these steps to diagnose and resolve the error:
Completely shut down the copier and unplug it from the wall outlet.
If cleaning the sensor does not clear the error, the pressure mechanism bearings are likely slipping due to grease migration.
