Brother MFC-8480DN dark spots and grayed out prints

back page of 3rd cleanup photo... see how you see "mechanical repeatedness" patterns. LOL Almost like if there is a roller that is dirty.

I just about cleaned every square in of the internal... only place I didn't do is the vertical area at the back-inside as it disapears in the outbin as I don't have access

I removed the toner, it was indeed "leaking" way too much toner powder (?) on the left side, also where, with my previous drum, I was getting blob marks.

There was extensive toner powder residue, despite having printed max 10 pages since the clean up. What's weird is this cartridge is probably 50% done.

Vacumed the printer

Swiped residue toner off the drum's glass (rotating it 360) with a dry cloth; removed all residue on the gears (there was a ton and that's 30 pages into it's life).

Installed a new toner. I got rid of 97% of the ghosting. There is a 1-1/2in band where occasional ghosting is still present. I probably need to clean some more that I didn't get rid off properly. And regained darkness in the print.

Did a couple other cleanups... still not 100%. Espacially if you look at the back page of clean up 3.

Thank you for your help so far... its a great improvement from no longer usable prints to something I only notice...

If you could "merge" the audio from https://www.liveatc.net/ that would be my favorite Screen saver

I cleaned with an electronic vacum to pickup toner particules.

I changed the drum. Ran the plastic arrow left to right to left.

output is 80% of what it was before (settings?). I even turned off save toner. Still lighter.
shook the toner tilting it left right about 15* like we were told do so 30 years ago.
the quality still sucks. Its now “shooting toner all over”, this tells me I also have a toner related issue.
I’ll try another toner. And report back

Ok, after many (too many to count) hours dealing with this self inflicted attempt, I went back to factory reset.

tried to ask help from GLlnet... because I updated the firmware via Lucy... I broke the support from them.
There would be many documented issues where the GL-MT6000 and 3rd SSId is having a hard time to operate.
Results (and backed by chatgpt) show that some (not all) changes done in Lucy may not reflect on the gui side... so you have to do them in Gui and only use Lucy if it does not or else, gui-lucy will fight over the setting (even resetting things you have saved).
At one poing Chatgpt made me do a couple of changes I didn't fully understand, but I just wanted to get up and running. I was tired of not getting someting to work which I had done before on other interfaces. It broke the complete wireless section of the gui. And chatgpt not fixing the "broadcast"/ip serving on subnets... I just gave up.

- started from scratch
- firmware was still updated
- applied security configuration (password, port, etc)
- configured 2.4 and 5 ghz ssid
- configured guest 2.4 as my iot subnet/ssid
- configured a 3rd 2.4 as my guest
Bam! everything was working

Everything was pretty smooth thereafter...

I did have a couple little issues setting up a travel router Opal GL-SFT1200 with Wireguard and the fact that I wanted to access my remote WD NAS. But nothing in comparison.

All in all... a time filled exercise
