Thank you for waiting.
Please try the below steps:
The Semi full Reset:
[while applying power]
Press WIFI Direct + Color Copy
The Full Reset:
[while applying power]
Press WIFI Direct + Black Copy
Note:
Unplug the power cord, then hold the Wi-Fi + color copy buttons, and then plug the power cord into the printer while holding both the buttons to access the reset menu, then you can let go of the buttons and use the menu to select the reset option.
We suggest you try the partial reset first, if it doesn't work, try the same steps as above and this time select a full reset to resolve the issue.
