Canon imageCLASS D570i error E003: Low Temperature Fault

The Canon imageCLASS D570i error E003 is a low-temperature alert in the fuser unit. This code flags that the unit has failed to hit the necessary operational heat, rendering printing impossible. Why is my Canon imageCLASS D570i showing error E003? It is typically a thermistor failure or a burnt-out heating lamp. This printer is reliable, but relies on consistent thermal regulation for its operation.

Common causes

  • 1Burnt-out Heat Lamp: Main heating element failed.
  • 2Thermistor Failure: Sensor reports false temperature.
  • 3Voltage Fluctuation: Low power prevents heating.
  • 4Component Fatigue: Heating element has reached its end of life.

Solutions

Quick Diagnosis

E003 is the opposite of the overheating error. If the back of the unit remains cold after a warmup attempt, the heating component has failed.

Step-by-Step Solution

  1. Power Reset: Unplug for 15 minutes to clear internal electronics.
  2. Stable Outlet: Connect directly to a wall power source to prevent voltage dips.
  3. Visual Check: Ensure no debris is blocking the rear exit unit.
  4. Power Test: Reboot and listen for the printer reaching 'Ready' status.

Prevention and Maintenance

Avoid freezing or very cold environments. Always use original Canon 137 consumables to ensure the fuser doesn't overwork.

When to Call a Technician

If E003 persists despite power resetting, the internal heat lamp requires hardware replacement.

Equipment Technical Data

  • Technology: Monochrome Laser
  • Speed: 28 ppm
  • Connectivity: USB, Wi-Fi
  • Consumable: Canon 137 cartridge
  • Recommended Use: Office/Small business
  • Official drivers/firmware

Steps to follow

  1. 1

    Power cycle

    Unplug the device for 15 minutes; cooldown cycles help stabilize the thermal sensor.

  2. 2

    Stable connection

    Ensure the cord is secure and connected to a dedicated wall socket to avoid voltage drops.

  3. 3

    Fuser test

    If E003 persists, the thermistor is likely failing to read the lamp's temperature.

Frequently asked questions

Error E003 means the fuser is too cold to operate, which prevents printing to protect toner quality.

If restarting fails to clear the code, professional repair is required.

Use Canon 137 cartridges for optimal thermal compatibility.

Store in a moderate temperature room and maintain a solid power connection.
