I get a "MACHINE ERROR 77" code when I power up my MFC-8500. I called Brother but they just want me to send it to a repair facility. I'd rather eBay the unit than pay a premium to get it repaired. The best I can figure out is that it has something to do with the fuser or the heat thermostat. Can anyone help to pinpoint a remedy for my MFC-8500?
I just got the same message on my mfc-8500 after a brief power outage.
I opened the front panel, removed the toner and closed the panel. The printer tried to warm up and then said to open the panel door. I then opened the door, inserted the toner, closed it and the machine error was cleared.
Perhaps all you need to do is remove the toner and put it back in. I was just letting you know every step that I took.
Wow! I know your post was from 2004 but we experienced a power outage yesterday at work. My fax had the error 77 on it. I was about to call Brother but decide to search on the net first. I did the same as you, took the toner out, closed the door and then replaced the toner....it worked. THANKS! THANKS! THANKS!
Thank you! Just had a power outage, and my Brother MFC-4800 had the same error. I followed your instructions, but still had the error. I entered 99 to reset the machine and the "error 77" was replaced with a message to insert the drum; inserted drum, and we are back in action! Thank you!
Power off the printer for 15 minutes and power back on again. If that fixes the problem then OK. If not then go into maintenance mode - Press and hold the menu/set key while turning on the machine. Wait until it comes completely up before releasing. It should say Maintenance in the display.
If not press function,*,2,8,6,4 within two seconds. It should say maintenance in the display. Or on some machines Menu,*,2,8,6,4 within 2 seconds.
Once you get it into maintenance hit 91 to do a parameter reset and than 99 to get out of maintenance.
If this corrects the problem then OK but you may have a failing thermister in the fuser. If the problem happens again then change the thermister.
If the reset does not work then either the thermister or the fuser lamp has failed. In rare cases there is a poor connection with the cables to the fuser.
You will have to reset the parameter again after replacing the fuser if you need to replace the fuser or repair it.
This same thing worked on our Brother IntelliFax 4100. The machine error 77 came up. Power cycling did not fix the problem. Powering off, removing the toner cartridge, power on, wait for error to replace toner fixed the problem. 30 seconds on Google saved 30 minutes of hassle on the phone.
I had the same error message; machine error 77 on a Brother MFC4800. It said to unplug the machine and call brother. I unplugged the machine and then plugged the machine back in. Same error message appeared machine error 77. However came back a few days later to reevaluate and everything works fine. However I do remember that I opened the machine to remove the drum and replaced the drum. Maybe that is a power cycle. Anyhow it seems to be working. Maybe power cycling is the key to functionality.
You reset all Brother fax machines the same way. Press function, *, 2,8,6,4 all within 2 seconds to place the machine into the maintanence mode. Press 0,1 to perform a parameter reset. this will restore the machine to factory default settings. press 9,9 to exit maint mode
I inherited my MFC 8500 for my home office and it came without instructions. If anyone knows WHERE I CAN FIND INSTRUCTION MANUEL I would really appreciate it!\ thanks crystal
I am getting the machine error 77 as well - - Power cycling and trying to get into the maintenance has failed. However I must mention tho' that there is no "function button" on this model. So i just followed the Menu/Set button - no avail...I am still not able to get the maintenance console up! Please advise - Thanks in advance guys>
Re: Machine Error 77 Brother MFC-4800 by Davy Boy (9/29/06 9:54 AM) reply
Hi guys, same problem occured here! Power outage then error 77 on startup!
Fix that worked for me was Menu Button * 9 1 (parameter init), and then Menu Button * 9 9 (Full reset).
That reset the internal levels etc... and everything appears to work fine!
This was after I contacted a local Brother Support Center, that quoted me $35 + $65 labor for a replacement thermal fuse.
Glad I saved me $100!
Also, a nice online test for receiving a fax was faxzero.com. We didn't have access to another fax machine to do a test fax, so this online service that sent out a test fax to our machine was invaluable!
I had the same error #77 after a power outage. I turned the machine off ,removed the toner and turned it on.It recycled asked to put the toner in and then the error cleared. Thanks guys saved me a lot of grief.
I have a MFC 9070 with same Machine error 77. I change the fuser unit, with an other FAX-8070. Doesn't work... Then i discover your marvellous forum, and use Laserman method, to go in maintenance menu, enter 99 code, and the machine works well now.
Great forum, this. Powering off, removing the toner cartridge, power on, wait for error saying to replace toner, then replaced toner (with power on)- fixed the problem.
I love the internet for this reason. I hate sitting on hold waiting for someone to tell me to power off, power on, push some buttons etc..... Thank you everyone for your help! I did have to get to the maintenance screen, not just remove/replace the toner, but It's fixed now! Back in business.
Thanks! I have a 4800 and, while removing and reinserting the drum didn't work, using *2864 worked. I had to do it a couple times before I got it right and got to the maintenance screen, but everything is working great now!
Hi everybody. I just had this same problem on my Intellifax 4100. I called tech support and they walked me through the repair.
Procedure is:
1) Unplug machine. 2) Hold down menu key. Plug in machine. 3) Release menu key. 4) Enter 91 5) Enter 99 6) Machine will warm up. 7) Press Reports key, then 1. This will test if the machine can print.
It worked for me, and hopefully, will save you all some Ebay costs.
This worked for my 4800 - power cycling alone did not work:
1) Unplug machine. 2) Hold down menu key while plugging in machine. 3) Enter 99 while holding down menu key 4) After it says "PLease wait" hit the stop/exit button to get out of the maintenance mode
I had a machine error 6a on my MFC - 8820D, and it happened after a power outage. Followed menu,*,2,8,6,4 followed by menu,*9,9 and vola...all fixed. Thanks guys. Saved a lot of moeny and time
Re: Machine Error 77 Brother MFC-8500 by Master D (1/28/07 2:40 PM) reply
Fixed! (for now...don't trust these things). I don't know the technical words to describe what I did, but:
Took the drum and toner out, separated toner from drum. Saw that the bluish cylinder in the drum unit had a stripe where it would have contacted the toner. There was a plastic wheel where you could turn the cylinder. I gave it a 1/4 turn, reassembled and re-inserted and voila! No error.
Not sure if this means there is a mechanism to turn the cylinder that isn't working on my machine, or if it is a routine maintenance issue, or what.
I haven't seen this fix anywhere else online--maybe it's just a coincidence that it worked anyway--so I'm posting in case it might help someone like me.
Just wanted to thank you for your detailed instructions. although i have a mfc4800, the "menu * 2864" trick is the only thing that worked. you saved me many hours of suffering to fix this machine!

This also worked for me. We didnt have a power outage as far as I know, but an end user had called me. Did a quick google and sure enough; power off, remove toner, reinsert toner, power on = no more error.
1) Unplug machine. 2) Hold down menu key. Plug in machine. 3) Release menu key. 4) Enter 91 5) Enter 99 6) Machine will warm up. 7) Press Reports key, then 1. This will test if the machine can print.
Many thanks for this post. Saved me buying a new fax I did not need.

See the below fix - worked for me. Only thing is that after you release the menu key, no maintenance menu shows up, but you just hit "91" and it initializes. Great! Thanks!

Sorry but I can't talk about my problem in English. Tengo una multifunción Brother MFC-4800, y actualmente me está dando un mensaje que tengo que cambiar el Jump. Como ese es un repuesto que aca en Uruguay está muy caro, me saldría mas encuenta comprar una impresora nueva. Pero me han dicho que el Jump es una especie de contador de copias, que se podría modificar, pero no me saben decir de donde bajar el software para resetear el mismo. Les agradezco si alguien tiene conocimiento sobre este problema, me lo haga saber.. De nuevo gracias, y quedo a la espera.. Un saludo cordial a todos... Manuel
WOW. I just got error on Brother fax also. I called and they wanted me to send in. I checked internet and found this post. Removed toner and re-insterted. All errors cleared. MANY thanks!!!!
After the fuser unit change on a MFC-8820D with a brand new one, the following message is visible on the control panel :
Error 6A, turn off the printer and call service.
Here is what I've done :
- Turn off the printer - Unplug the power cable - Hold the menu key down - Plug the power cord back - The common green led is blinking - Type 99 on the numeric pad - When the 'Please Wait' msg appears, type the Stop key to exit maintenance mode.
Parece que no me hice entender, la máquina que tengo con problemas de "Jump" es una Brother MCF4800, y es sobre ella que estoy consultando. Sorry, but I can't talk very good about my problem in English, but my Brother is an MCF4800 and it said "change jump" and I need a software to reset the jump. Thanks
This worked for my Brother DCP-1000 copier/printer/scanner.
1) Unplug machine. 2) Hold down menu key. Plug in machine. 3) Release menu key. 4) Enter 91 5) Enter 99 6) Machine will warm up.
I didn't think anything was happening when I tried plugging it back in while holding the menu key because the error message still showed up the first few times. I finally just continued with the rest of the steps and the error message went away and the machine started humming.
Thank you so much for the tip. I tried the tip pull out the toner and put it back, it didn't work. then I saw your tip "Menu Button * 9 " and tried, the machine went back to normal mode, error 77 disappeared. thanks again.
Had a power outage over the weekend and two of the MFC-8500 run into this problem. I found this link.
For the first of the two machines, after trying everything, I replaced it with a third MFC-8500, which was off during the power failure.
For the second, I tried everything suggested here: Did not work! I went to menu, chose fax, and it was checking drum. Suddenly, it works now. This is after inventing all kinds of other tests.

Worked like a charm! Good luck!
This worked for my Brother DCP -1000! I was getting the Machine Error 77 message.
I had the Machine Error 6A on a brother MFC8840D and did the resets that are on this post. It seems to have cleared the error but now on start up all it asks for is Pls Open Cover and gives me no other error code.
Is there anything else i can look for or check?
Thanks, Nick
Re: Machine Error 77 Brother MFC-8500 by Nick London (10/25/07 1:30 AM) reply
NO es el jump si no el drum y en el manual viene como resetearse, solo q a veces no basta con eso, porq a pesar de q si se resetea, en ocasiones el drum ya esta deteriorado y las impresiones no son muy optimas, salen fantasmas de texto (partes en blanco) o lineas transparentes, etc. La forma de resetearse es abrir la cubierta de enfrente y pulsar las fechas, te va a preguntar si quieres reemplazar el drum (o tambor) le dices q si, cierras la cubierta y listo. Espero te sirva.
...just had to say thanks for your tip!I'm actually a fax/printer engineer but a human one hence I accidentally left the thermistor unplugged after replacing the upper fuser roller. I actually smelt smoke so I was sure something had blown,i.e one of the two thermal fuses but neither of them were o/c neither was the lamp.Anyway I tried everything posted on the site in the order they were listed but not till I read your instructions did the machine fire up.Thanks for taking the time to post your knowledge i'll have to do the same now!!!
kind regards

Brother class action suit!!! ABOUT TIME! by emkay (11/5/07 9:21 AM) reply
I think its HIGH time someone took Brother to task!
You may even be due compensation!
PLEASE: Copy this to as many forums as you can and get more people on board to give Brother what they justly deserve and to see some justice done on behalf of all of us who have had sot suffer their poor products and poor customer service!
This works for the MFC-9700 too - We lost power and the machine error 77 came up when the power back on. Followed this procedure and everything worked great...
1) Unplug machine. 2) Hold down menu key. Plug in machine. 3) Release menu key. 4) Enter 91 5) Enter 99 6) Machine will warm up.
Machine Error s 76 and 77 Brother MFC-8500 (9700) by Anonymous (12/17/07 7:25 AM) reply
Laserman thank you so much for your detailed instructions. I tried most of the other instructions listed on this website and got nowhere. I have a MFC 9700 that had errors 76 and 77. When I came across your instructions, I decided to try to fix it one last time. If it didn't work at that point the machine would learn how to fly! Lucky for the MFC it worked.
1) Unplug machine. 2) Hold down menu key while plugging in machine. 3) Enter 99 while holding down menu key 4) After it says "PLease wait" hit the stop/exit button to get out of the maintenance mode
This worked perfectly. I first called in our local store and they said 77 is a fuser error. They invited me to come and change it... No idea what it would have costed.
1. Unplug machine 2. take out toner with drum 3. Plug machine back 4. wait the message "insert toner" 5. insert back in the toner with drum 6. it works now
I have an mcf-6800 with the same error 77.did the steps *2864 and the screen said maint. then went back to error mess.I was almost discouraged and quit but I pushed the 91 anyway and maint. flashed again then went back to error 77 then I hit the 99 and it cycled and was fixed.just do the steps and do not worry what the screen says and it will work fine.THANKS SO MUCH FOR THE TIPS THIS GOOGLE THING IS REALLY GREAT!!!
Machine error 77 Brother MFC-9030 by small (1/8/08 9:12 AM) reply
I use a Brother MFC-9030 and like all of you I get a "error machine 77" after a power outage.
To get back my fax I : 1) Unplug machine. 2) Hold down menu key. Plug in machine. 3) Release menu key. 4) Enter 91 5) Enter 99 6) Machine will warm up.
French version : J'utilise un fax Brother MFC-9030 et comme vous tous, j'ai obtenu le message d'erreur "erreur machine 77, contactez votre revendeur" Pour régler le problème : 1) Débrancher le fax 2) Tenir appuyée la touche menu et rebrancher le fax 3) Relacher la touche menu après quelques secondes 4) Entrez 91 5) Entrez 99 6) Le fax reboote tout seul et ca fonctionne!
Both of them had Error 77 and76 respectively following half-power outage overnight.
The procedure worked perfectly on one printer Code 77, that had a document waiting to print.
Tried it on the other one standing by with code 76. After the drum shake out the code changed to 77. Loaded the document to print, nothing. Still Error 77.
I will leave it unplugged for few hours and try again.
Saw that the bluish cylinder in the drum unit had a stripe where it would have contacted the toner. There was a plastic wheel where you could turn the cylinder. I gave it a 1/4 turn, reassembled and re-inserted and voila! No error.>
Hi-I don't know the machine, just the symptoms. Normally tbis is dried tippex on the glass used to read the outgoing document. If you can locate this, you may be able to use the smallest precision screwdriver you can lay your hands on to clean it off the glass. Don't rush in, be careful... it may be under a paper feed roller.
Solution worked for me too. Unplug, hold down Menu, plug in (still holding Menu down) and totally IGNORE the machine beeping and complaining about Error 77. Just type 91 and shortly after, 99 and it'll reset!
Cannot thank you enough for this advise. You have fixed my machine! I would like to also add:
This also works on a MFC 9180
If after you have pressed function, *,2,8,6,4 and "maintenance" flashes up on the screen and is instantly replaced by the Error 77 message, just continue with 91 then 99.
Just wanted to thank you for your tips! I tried all the other steps in this thread to no avail then tried your suggestion: >Menu Button * 9 1 (parameter init), and then Menu Button * 9 9 (Full reset) That worked like a charm! Now my MFC-6800 is working again good as new.
I understand that all Brothers are reset the same way with the *2864, but my 6800 doesn't have a key marked "function". Which key would take the place of a function key? Menu key doesn't work either. HELP
My machine is saying machine error 76 on a MFC-8500 Any suggestions????? I tried the ones mentioned for error 77 but they didn't work! Thanks in advance for your help.
Thank you for your detailed post. by Anonymous (6/15/08 6:37 PM) reply
Thank you so much for your post! When I turned my printer firt time after a whole week without power, I got Error 77 message. I googled and found your post. It was very helpfull! Thank you!
A million thanks! I just sucessfully reset my Brother Intellifax after unplugging it, removing the toner, and even cursing at it did not help. You guys are awesome!
Try this....... 1. Unplug power cord from rear of machine. 2. Press "menu" key and simultaneously reconnect power cord. 3. Wait a few seconds and enter *91 4. Wait a few more seconds and enter *99 5. Machine will intialize and reset to factory default parameters.
You may have to repeat these steps a couple times before the unit resets.
In my experience Brother units display Error 71 & 77 after a power interruption or surge/spike...its just part of doing business with an otherwise "user friendly" and very reliable family of printers and fax machines.
Please note the reset proceedure may erase some or all user settings...example: date, time, Station ID, phone and fax numbers, etc. Use menu key to re-enter info. If you have questions refer to your owners manual. Hope this helps, Frank-ALFA
I received a Machine Error 77 Brother on a MFC-4100e. I called Brother and they had me bring the machine up in maintenance mode and press 31 then 39 the machine seemed to be fixed but now the machine doesn't want to stay connected while sending or receiving faxes. It will pickup and then disconnect or receive some of the pages and cut off, and the same with sending. I have done everything that has been posted on this page and nothing seems to work. I have had the phone company out to check the line, I have changed the jacks and cords and re-punched down the cables in the 66 and 110 blocks. Can someone please help me?
-Is your web browsing affected? -Is your machine slower then it used to be?
-What is your computer literacy?
In any case, do get Ad-Aware, and the Spy-Bot. -Perhaps even simpler steps might help, like deleting all your temporary files, and cookies by going to Tools, Internet options, Privacy, etc.
There is a lot to explore there, enough not to be bothered with Nortons, McAffe and all other Panda nuisance.

My MFC 8500 took on a power outage. Now it get through about four pages and it sounds like something just breaks loose and starts spinning very fast. Then it generates and error and has to be reset. Any ideas? Thanks - Dan
Take the drum out, and look at the roll. I may have a slick line the full length of the drum. Rachet the roll to move the line away. Insert the drum and try again. Good luck.
