DCP-8050DN toner won't reset

[Lance15]

I replaced the toner (TN-620) in this Brother printer, but, it's still saying Toner Low Prepare New Toner Cartridge. I followed the instructions and some troubleshooting I found on Brother's website. It still won't recognize the toner was replaced.

Here's what I did (following the instructions):
Remove old toner cartridge from drum unit
Remove new toner cartridge from box
Shake toner back and forth
Remove yellow plastic covering the dev roller
Install new toner into drum unit
Clean the corona wire
Reinstall into the printer

The printer spins up, warms the fuser and then goes back to Toner Low. Am I missing something?

Every Brother I know has toner reset sequence of buttons etc. I don't know for this toner as it's not available here, but try this:
TN-620 & TN-650 Toner Reset Instruction | 123ink.ca blog
Or just watch some You tube videos how to put reset gears in position for the toner cartridge to be recognized as new.
Good luck

Re: DCP-8050DN toner won't reset

Those instructions aren't for the DCP series. When I was looking at the cartridge, I was thinking more along the lines of a reset gear/mechanism. Looks like I was thinking right. Will have to look at it tomorrow. Thank you for your response.

I dunno. I'm confused. I reset the gear. Still says Toner Low. Found how to access Maintenance Mode and tested the Toner New (TN) sensor and it's working. I tried resetting the original toner cartridge gear and still get Toner Low. Still prints, just keeps saying Toner Low.

In case anything is working for new toner to be recognized, I will print settings list and do memory clear from Maintenance mode. Never ever had main PCB going wacky to not recognize new toners at all.

Re: DCP-8050DN toner won't reset

try the dev reset... or check the right manual for it... have had that problem on a lot of the brother units

Using your method and selecting the [*], [0], [0] option worked! Thank You!

It doesn't look like Brother chips supplies/parts. I noticed to clear pretty much anything requires the use of the Maintenance Mode.

I know at one time I HAD the SM/PL for THAT model.. now poof.

But did find out the Dev reset on MANY models over rides the " replace toner " even on the early color/mfp units.

Glad to see not ALL the grey matter is failing

Re: DCP-8050DN toner won't reset

Yeah. I came across the SM for the 8040, 8060 and maybe another one. Figured I could figure SOMEthing out between them.

It's my personal printer that my wife got for free from work, so, I wasn't so concerned.
