Canon imagePRESS C910 Error E003-0004: Troubleshooting

The Canon imagePRESS C910 error E003-0004 is triggered when the fuser's temperature sensor reports an inconsistency. Essentially, the fuser fails to reach or maintain the set point temperature, which is critical for toner fixation. Users frequently ask why does my Canon imagePRESS C910 show E003-0004, often when switching between lightweight and heavy paper stocks.

Common causes

  • 1Lamp Failure: Fuser lamp is blown or disconnected.
  • 2Thermistor Malfunction: The sensor is reporting incorrect values.
  • 3Voltage Instability: Inadequate power supply inhibits heating.
  • 4Thermal Wear: Fuser assembly parts are nearing end-of-life.

Solutions

Quick Diagnostics

The E003-0004 error is a temperature calibration failure. The printer locks up immediately to prevent incomplete toner fixation (offsetting).

Step-by-Step Resolution

  1. Power Down: Turn off the printer and wait for 15 minutes.
  2. Voltage Check: Ensure the printer has a stable, dedicated power source.
  3. Power Cycle: Restart and allow the machine to run its warm-up test.
  4. Service: If the fault returns, the fuser lamp or thermistor is likely failing.

Prevention and Maintenance

Always check your power delivery. Insufficient current can cause fuser temperature drops during high-speed printing.

When to call a technician

This error requires servicing the internal heating assembly, which involves delicate electrical and thermal components.

Frequently asked questions

It refers to an incorrect temperature reading in the fuser, where the sensor detects that it is not reaching the required degrees within the allotted time.

Turning it off may help temporarily, but if the lamp or thermistor is faulty, the error will immediately recur.

It uses T03 toner, which is vital for maintaining fuser longevity.
