Ricoh SC324 — Laser diode current over limit

What this error means

The laser diode is drawing more current than allowed — an aging LD unit announcing retirement. Service replacement.

Symptoms

• Print quality degrading before the error

Try this first (safe DIY steps)

1. Power off at the main switch, wait 60 seconds, power on
2. If it recurs, note the full code (including any detail digits) for the service call

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 — LD unit replacement.
