Inspect the wiring harness connecting to the sensor for pinches, cuts, or loose crimps. 4. Test the Lift Motor and Drive Gears
High-volume printing wears down the teeth of the one-way gear inside the fuser/exit drive block, or slips the rubber timing belts off their tracks. sc569-00 ricoh
The most common cause. If a piece of paper wraps tightly around the pressure roller or heat sleeve, it physically binds the mechanism, preventing the pressure release motor from turning. Inspect the wiring harness connecting to the sensor
Locate the pressure drive assembly and disassemble the one-way bearings. The most common cause
Vacuum paper dust and toner residue away from the fuser bay every time you replace a toner cartridge or PM kit.
When a Ricoh machine warms up to roughly 150°C, it activates the pressure release motor to test the fusing belt or roller tension. If this mechanical loop fails, the system triggers the SC569-00 code. The issue typically stems from four specific sources:
Even a tiny scrap of paper in the fuser area can block the motor. Clean the Sensors: Dust on the pressure release sensor is a common culprit. Hard Reset: Power down, unplug for a minute, and restart. If the code persists, you may need to clear it through SP Mode 5-810 The fuser is
