The board that powers the motor might be faulty. Troubleshooting and Fixes for SC569-00
This Service Call (SC) error code occurs when the machine's control board fails to receive a proper signal from the pressure release sensor within a specified timeframe during the fuser unit's initialization test. The error disrupts workflow because it causes the multifunction printer (MFP) to halt all printing and copying operations immediately to protect its internal mechanics. Primary Causes of the SC569-00 Error
Manually rotate the fuser drive gears and pressure release cams to ensure fluid, unhindered motion. Step 3: Clean and Test the Home Position Sensor
In simpler terms, the printer detected a mechanical problem while trying to control the pressure within the fusing unit. The system repeatedly failed to confirm that a mechanical part had moved to its correct position. After multiple failed attempts, it triggers SC569-00 and halts operation to prevent potential hardware damage.
Troubleshooting Ricoh Error Code SC569-00: A Quick Guide If your Ricoh multifunction printer has ground to a halt with , 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.
Locate the alignment fence home sensor input (check service manual for bit number, typically like "Finisher HP Sensor" or "Align HP").
Note: Depending on whether your machine features an older physical keyboard panel or a newer Android-based Smart Operation Panel, choose the appropriate access method below. For Modern Smart Operation Panels (Android Touchscreens)
: The pressure release sensor (often U-shaped) may be dirty, displaced, or faulty due to high heat exposure.
Turn the copier off using the main power toggle, wait 10 seconds, and restart. Preventative Maintenance Tips
Pull out the fuser assembly and look to the left side of the cavity.
Before replacing any parts, inspect the tracking sensor located inside the machine's fuser cavity.
When installing a new fuser belt or pressure roller, proactively swap out the pressure release sensor. The sensor degrades over time due to intense heat exposure.
A: While a component can fail suddenly, the error often develops gradually. Increased friction from a lack of lubrication or a slowly failing one-way gear can cause the motor to require more effort to move the mechanism. Eventually, the motor's timing is off by enough to trigger the error. Intermittent errors, such as the code appearing only when the machine enters a low-power state, are also common.
SC569-00 is not exclusive to one device. It has been documented in many popular models, including:
A loose connection is a surprisingly common cause.
Access the Ricoh Service Program (SP) mode by pressing (or the corresponding sequence for your specific model generation). On the digital touchscreen interface, select System SP . Open the Mode submenu (typically option 5). Locate command SP 5-810 (SC Reset) . Press Execute on the screen.
