Replacing the fuser roller on a Brother HL-3170 CDW laser printer

Thanks for your video and where to buy the roller? I have one mfc 3770 to repair but can't find the roller for sale online.

Please explain why you had to do this. What was the problem?

My Brother printer is the same model number but does not look anything like the video and has no access at the front like in the video 🤔

Thank you, this video helped me a lot fixing my wifes printer and you know: Happy wife, happy life ;-)

Do you have a preferred supplier for the fuser roller? BTW great video, very well done.

Thanks! This helped me successfully change the fuser pressure roller (orange) on a HL-4570CDW :) Quite similar

Great video! i was successful dismantling, replacing both rollers and reassembling. My problem now is I'm getting Print Unable 05, along with "Self-Diagnostic will automatically restart within 15 minutes". Any thoughts what I may have done wrong?

... and we're back in business!!! Great repair vid!!!

Dude you are so generous!!! years ago I bought a monochrome brother printer, then upgraded twice to color brothers that used the same cartridges… and found that the majority of the replaceable parts were identical between the AIO hl-3180cdw I upgraded to and the hl-3170cdw I downgraded to when I couldn’t figure out what was wrong with the 3180.

I’ve got a bit more confident with taking apart machines that are otherwise bricked and I got out the 3180 to find that there’s most of a piece of paper tightly wrapped around the fuser roller. This video gives me exactly the teardown I need and the sku for the part I will quite likely need in the future
I’m so going to set parts search alerts on Craigslist now, this gets me closer to making these things basically continue working quite a bit longer. If the ifixit community doesn’t already have printer forums, they need them.

Are you over at iFixit too?
Make sure to create a Kofi account and connect it to your YT so fans can send you some tangible gratitude… I have an idea of just how much effort a video like this takes to light, shoot, and edit. Thank you SO MUCH!

Thank you so much for your video! We could not find a replacement printer locally so we were forced to replace the fuser roller. Thanks to your video, we installed it properly and were able to print a document of 10 pages with no overheating issue. We ordered the part from Amazon for $20. Thank you again!

You saved me a lot of money. I appreciate it. 💵💵💵💵💵💵💵

🙏🏼🥰

I have a 3270. Had to remove fuser assembly due to paper wrapped around. Removed all paper, put together carefully and still get self diagnostic when i turn on. Black fuser roller was in good shape. Any ideas?

Wow! Silence is truly golden! Great job, especially with those zoom-ins. I took apart as instructed and saw the damaged roller. I will look online and try to find a genuine part from Brother as after-market replacements could cause the machine to run hot after only a few prints. Or, please let me know if the printer you had fixed is running fine with the replacement you made. Awesome video: clear, nice and great views!

Great video. Thank you. I was quoted around $350 to fix the printer. Could have bought a new one for less. With the help of this video, I fixed it for $50. Got the new roller set from Amazon.

Thanks you legend! You helped me save my printer 😀

Thank you! so well done and we just replaced the rolls successfully! Very helpful.

Muchas gracias me sirvió mucho 🤝🤝🤝👍✋️

Thank you very much for this video, thanks to it I fixed the printer without any problems :)

Thank you for taking the time to post such an excellent video. Following your steps, I was able to successfully replace the upper fuser roller in my HL-3170CDW. Unfortunately, after reassembling mine, experienced the over heating problem indicated by the "Cooling Down" message. Was able to work around that. Wanted to share that and another tip with others.

First off, when finishing the reassemble, you had overlooked replacing the holding bracket on the right side. You caught that but referred users to watch the disassembly. There is a subtle step here that simplifies getting it all to fit back easily. Prior to re-installing the pivoting paper guide (the one with the lime green tabs), place the right holding bracket in place but leave it loose, do not fasten with a screw yet. Insert the left side mounting nub of the pivoting paper guide into the left round mounting hole. While swinging the paper guide into place on the right side, slightly pull the left edge of the loose right holding bracket outward to allow the right side mounting nub to slide into the mounting channel of the chassis. Then replace the screw while holding the right holding bracket in place.

The other tip is regarding the over heating issue. I recall reading a posting somewhere that some of the 3rd party fuser rollers were slightly oversized by perhaps 0.5mm. I believe that extra pressure may be part of the problem. I found that if I loosened the pressure roller tension adjustment tabs (dark green) to the middle intermediate position, normally used for printing envelops or thick stock, that the printer no longer paused for over heating. After printing quite a few pages, sometimes 4-5 pages continuously, I pushed the green tabs back up to the upper position (maximum tension/pressure) and it continued to print without pausing. Can't say with certainty that it is "fixed" but seems to be working now. Also, this was done while printing primarily text. It may print hotter if it is full page graphics with solid color. Hope that helps others.

Thanks again for such a useful video!

Great video! Replaced the fuser roller in my MFC 9340 for $20, Amazon. Thanks for helping me save some $$ !

Excellent instructional video! I opted for the replacing the entire fuser unit because I had reason to believe that there were other issues with the unit as well, but this was still very helpful! Thanks!

Darn, I busted the fuse😭

Nice video, good work!! Thanks!!

Thanks for the video, made my thrift store printer like new again.

Great video, thank you very much.

Great video!
Unfortunately, when I put it all back together, I got a "fusor error".

Thanks for this video - it was incredibly helpful and allowed us to replace our damaged fuser roller with confidence.

Thank you so much for sharing this kind of video. I like the quality, and the way you show us every steps in detail. Even for the beginners, they can do it their self by watching this video. Good job!

Thanks for the video. It helped a lot. And I must say that the Brother printers seem to be very good for fix it yourself.

Why aren't all repair videos like this? Thank you for taking your time to show us the details

Thank you soooooooo much! The entire fuser unit is nearly the price of a new printer @ 160UKP. Just fixed my 3150CDW using your video as a guide. Video was very clear. Thanks again!

This is very informative, thank you.

I’ve removed the Fuser assembly and similar to this, the black roller is torn(looks like by the metal teeth that make contact with it cut it by rolling the wrong direction).

I’m considering buying a replacement roller and using your vid as instruction as it’s about $20 and this seems doable. I’m also considering buying a replacement Fuser(NON Brother) from Amazon for about $120 just to ensure the unit works and I don’t foul something up replacing the roller myself.

I’m also considering just selling the whole printer(in great shape aside from the Fuser roller) for parts or repair and buying a black and white brother since I mainly just print text and shipping labels and they’re only $125-150. Any thoughts?

Cheers Long Peter. That's just saved me a fortune buying a new printer and it saves resources! I did laugh at the end when I was thinking "why didn't he fit those two electrical covers before putting the last bit on? I still followed your process... and then took that bit out again when I realised 🙂 Great job! and thanks again.

Thank you for doing this. It took me a little over an hour and my printer is working perfectly. I bought one of the knockoff fusers from Amazon so no telling if it will have overheating issues. Since we are a home user and only print a few pages at a time it may never be an issue. I did look for a Brother factory fuser was unable to find one online here in the US.

Just a few hours ago a simple paper jam broke this roller... Well, removing roller from a fuser seems not that hard as i thought. I guess the repair isn't hard. But it's a shame that roller can be broken so easily. ~11000 pages printed...

Fantastic video! I almost always skip over videos without much talking, but I'm glad I didn't skip yours! I've got a roller ordered for an 8610, so I'll be coming back for a second viewing before I start ripping into it. Good camera angles and your actions documented what steps you were taking.
Thank you!

Thank you very much 😂

Due to my clumsy hand broke a piece of plastic about half finger nail size, still manage to complete the mission. Thanks for your uplaod 😂

An absolute genius!! Super careful and precise to the dot. Well done and thanks for the video.

Excellent detail.

Thanks for the great video. I am having issues with poor toner fixing, and I can still manage a decent printed page if I tell the printer I've loaded envelopes to get the heat up, and I don't have ghost images or any smudging so I think the roller itself is okay. Can I tweak or replace the thermistor or the bulb by itself? I don't see bulbs offered - I'd prefer not to get a whole fuser; I'd be better served jumping to a new printer.

Peter, I love your video for changing the fuser rollers on a Brother L3170. Totally in my wheelhouse and just needed the walk through you created.

My only concern is the handling of the exposed aluminum tube on the gear side of the hot fuser roller. After installing the new black roller you bend the tabs on the gear side of the old roller. Is this to suggest the tabs of the new roller should have its tabs bent after installation in the gear? Are these tabs deformed or bent in the gear and do they need to be pushed back into concentric alignment before the bad roller can be remove?

Love your walk through, just don't understand the bending of the tabs on the old part and what that indicates for the rebuild process.

Thanks again,

Thank you for this video!

Thanks, Brother service desk quickly diagnosed my problem but told me the fuser unit had to be replaced by a service center. That would certainly have cost more than what you pay for a new laser printer these days.
But thanks to your video my printer is working fine again. Thanks !

Thank you. I replaced the whole fuser unit this afternoon. Your vid made it possible. I appreciate you.

Thank you Peter. My fuser roller had lost the top coating just like in your video. Replaced successfully. The only tricky parts were getting one of the tension springs back in place and getting the last right hand cover installed properly (the only bit that you didn't video).

Yes Peter when I originally made my series of videos in 2015 all I could afford was a potato phone, something that would have made my Irish ancestors proud. Are you aware that the roller you used in this video is one of the counterfeit rollers I talked about in one of my counterfeit roller videos. I'm betting your printer now says it's overheating (cooling down for a while) every time you send it a three or four page print job.
