Ricoh SC320 — Polygon motor error
Applies to: Aficio / MP / IM series
What this error means
The laser unit's polygon mirror motor failed to reach or hold speed — the machine can't write images.
Symptoms
- Error at power-on or first print
- Changing high-pitched whine beforehand
Try this first (safe DIY steps)
- Power cycle once
Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.
When to call a technician
On recurrence — laser unit replacement.
