Welcome, my name is XXXXX XXXXX I will assist you today!
There are many possible other repair steps that can be performed. Replacing the printhead is not a guranteed fix, its a possible
fix, but not guranteed. I would feel much better if we tried some other steps before trying to replace the printhead.
Especially since you mentioned there was a power failure. Most likely, your internal firmware was damaged, or the NVRAM has faulted, ( which stores the internal Operating system of the printer )
Lets try this reset first, even though this reset is made to fix a different issue, we need to see if the machine will respond to normal technical commands given to it.
Run through that reset in depth and let me know exactly what happens.
Also, there is a Firmware update tool... Meaning, there is a new version of the internal firmware for that printer.. I strongly
suggest updating the firmware as updating the firmware stands the greatest chance of fixing this issue.. To update the firmware go to the page belowhttp://welcome.solutions.brother.com/bsc/public/as/au/en/dlf/download_index.html?reg=as&c=au&lang=en&prod=dcpj125_all&type2=4&os=all&flang=all&dlid=
Download the appropriate firmware updater for whatever version of windows you have, and also, make sure you choose the correct language. As we dont want your printer suddenly speaking chinese , if you do not~
Once downloaded, you will need to be directly
connected to the printer via a usb cord. Do not
use a usb hub, and do not
use a network connection between computer and printer, when your updating the firmware.
Once the firmware update is absolutely finished.. Unplug the brother machine from power. ( do not just turn it off, actually unplug it )
And then plug it back in and then lets go over the status of the printer at that time. If its working, Great! If its not working, send a reply and let me know in detail everything you saw and everything that happened, and if you were able to successfully complete both
of the two steps I sent you.
I strive to provide great service, and greatly appreciate a rating of excellent below when you are satisfied.. I always answer follow up questions.
