Sc569-00 Ricoh May 2026

For business-critical machines, individual component repair is risky. Replace the entire fuser unit with a genuine Ricoh OEM unit. After replacement:

Before you begin: Turn off the printer, unplug the power cord, and allow the fuser to cool for at least 30 minutes. These components operate at over 350°F (180°C). sc569-00 ricoh

Third-party fusers often use lower-grade thermistors and sleeves. The cost savings rarely justify the downtime from recurring SC codes. These components operate at over 350°F (180°C)

| Priority | Cause | Explanation | |----------|-------|-------------| | 1 | Paper debris / staples | Tiny paper pieces or a loose staple lodged near the alignment fence guide rails. | | 2 | Alignment fence mechanical binding | Fence skewed, rail dirty/warped, or spring detached. | | 3 | Home position sensor failure | Sensor dirty, disconnected, or failed (e.g., photo-interrupter stuck ON/OFF). | | 4 | Alignment fence motor failure | Motor not turning (open winding, broken gear, harness fault). | | 5 | Motor drive circuit / harness | Broken wire between finisher controller board and motor/sensor. | | 6 | Finisher main board failure | Rare; typically last resort. |

The fusing lamp provides heat. As it ages, its internal resistance changes, leading to erratic zero-cross signals. In some cases, the lamp may have a micro-crack that only fails when hot.
