The error code E000021-0400 on a Canon C5240A typically indicates a problem with the fixing assembly temperature sensor. The fixing assembly is the part of the printer that fuses toner onto the paper, and it relies on a temperature sensor to ensure that the temperature is maintained within a certain range.
The specific error code E000021-0400 usually indicates that the temperature sensor has detected a problem with the temperature reading. This could be caused by a malfunctioning sensor, a problem with the wiring, or a problem with the fixing assembly itself.
To resolve this issue, you may need to replace the temperature sensor or the entire fixing assembly. However, before doing so, you can try resetting the printer by turning it off and on again. If the error persists, you may need to contact a qualified technician for assistance.
