Sc569-00 Ricoh [repack] Now

If the SC569-00 error code appears immediately after powering on, or if the hard reset does not resolve it, it is likely that the or the fuser sensor needs to be replaced.

: The U-shaped photo-interrupter sensor inside the fuser cavity detects the rotation of a half-moon (semicircle) gear. Toner dust, paper lint, or accidental impacts can block or knock this sensor out of alignment.

Open the side drawer/door of the copier and pull out the fuser assembly.

Before replacing expensive parts, follow this technician-grade diagnostic sequence.

: The pressure release motor itself may have failed or disconnected. Obstructions

The motor that drives the semi-circular gears to lift or lower the pressure roller may be burnt out, seized, or lacking voltage.

When a heavy-duty copier warms up or processes variable paper stocks, it dynamically adjusts the physical pressure between the hot fuser roller and the pressure roller. When the machine reaches roughly 150°C during warm-up, it cycles the pressure lift motor to test the system. If the sensor does not register this movement within a designated time window, the system throws the SC569-00 code and halts operation to prevent physical damage. Open the side drawer/door of the copier and

Manually rotate the gear train linked to the pressure release motor to ensure smooth rotation.

Mechanical blockage in the fuser unit preventing the pressure roller from releasing.

Open the machine and ensure the fuser unit is fully and correctly seated. In some models, like the MP C6502, an incorrectly seated unit can cause a shock to the heater terminals and lead to additional errors like SC555-00.
