Canon E000 — Fuser temperature failure (no warm-up)

What this error means

The fixing (fuser) unit did not reach its target temperature during startup. The machine locks itself out to prevent fire risk, and on most imageRUNNER models this error latches until it is cleared in service mode.

Symptoms

• Machine stops during warm-up
• E000 shown immediately after power-on
• Error returns after every restart

Try this first (safe DIY steps)

1. Power the machine off at the main switch, wait 60 seconds, and power back on
2. Check that the fuser unit is fully seated (open the right/front cover per your model manual)
3. If the error persists after two power cycles, stop — repeated resets against a real fuser fault can damage the unit

Safety: power off before any physical intervention. Never bypass covers or interlocks — fuser areas run hot enough to burn.

When to call a technician

If two power cycles don't clear it. The fuser heater, thermistor, or thermal switch usually needs testing or replacement, and the latched error must be reset in service mode.
