Error Code E744-6000 / Printer Model: MF733Cdw

[jacquelinehe]

The error code happened after a new router setup. 

In meantime, the printer was reset the wifi connection, but this code keeps showing up by every 2-3 days.

This happened to me too. And I just dropped over $300 on toner replacement for this thing.

Hello Jaquelinehe,

If the error keeps coming up, it looks like there is a problem with wifi module on the printer or the printer's firmware needs to be updated. You can try updating the firmware using the steps in the link provided HERE. If you update the firmware and you continue to have the issue, it will mean the printer needs service.

You can log into your Canon account using the link provided HERE to check your service options or you can contact support at 1-800-652-2666.
