Brother Brother Compactronic I

Brother HL-1650 Error Codes

Having spent some time working on the HL-1650, I list below some of the error codes that are useful:-

E50 Fuser Unit Fault
(Can result when the heat roller is damaged or u/s)

E51 Laser Beam Protection Fault
(If you have been inside the laser unit and adjusted the mirrors, beam or not seated the lid properly)

E52 Laser Motor Unit Fault
(As it says, Laser Motor Unit is u/s)

E54 Main Motor Fault
(Motor is jammed or u/s)

S05 Data Bus Error
(seen when there has been a problem with data being sent on Parallel Port - Rebooting the PC often clears this)

Pete
These are pretty much the same error codes Canon uses with the exception of the "E" in front of them. Brother used to use Canon engines before they decided to make their own (big mistake). Their first laser printers were built around Canon toner cartridges, using the same error codes. Later models mostly dispensed with luxuries like display panels and used idiot lights along with separate toner and drum cartridges. Might as well buy a new printer for the cost of replacing a toner and drum cartridge.

I have the error e52 being displayed, is there any chance of fixing it myself?
If so How?
Thanks

Graham,

I just had the same problem on my HL-1650 today. Coincidence?

Does your printer make a loud howling noise for about 5 seconds and then quiet down and display the E52 message?

I took the printer apart as far as I was comfortable doing, but I never got down to the motor in the middle of the printer that is making all of the noise.

I am going to call the local printer repair company and see what they get to fix this thing, or if they will sell me the part.

My wife found a good deal on a HL-5250 DNT for $262.59 at Amazon.com. I am considering buying it if the repair costs too much. I really loved the HL-1650 and would prefer to repair it.

I just sent away for a parts manual on CD-ROM for the 1650. I found a laser unit for $125.00 from NESS, their part number LJ5604001.

Does anyone know of another source for the laser unit?

Thanks,

Greg

After receiving the parts manual CD, I was brave enough to take apart the laser unit and found that the polygon motor was causing the loud noise and the E52 message.

Does anyone know where I can buy a new polygon motor, separate from the laser unit?

Thanks,

Greg

If you read this thread than you can see that the polygon motor is causing this problem.
by spin2 on Aug 5, 2006 at 11:08am Add comment
In fact the noise/E52 service problem might be easy to fix:

You just have to oil the mirror motor shaft in the laser unit.

Step-by-step instruction:

1 – Remove gently the top cover of the printer ( 4 screws – 2 on top/front + 2 in back/side).
2 – Be careful with the connectors going to the top LCD panel. You might want to disconnect the shorter one.
3 – Remove the laser unit located on top of the printer covered by a steel plate.

To do that:
1 – Unplug (pull) the white flat connector going to the left side of the laser unit.
2 – Unscrew the 3 screws keeping the laser unit in place.
3 – The lower/right screw also maintains in place the second connector going to the unit. Remove it and unplug (pull) the connector.
4 – Squeeze out the laser unit from under the wires (going back and up).

You now have the laser unit outside of the printer.
1 - Remove the steel plate of the laser unit. There is a plastic shutter that will come loose. Don’t loose it and take note of its location in case you need to put it back.
2 – Unscrew the 4 screws maintaining the motor section and remove it.
3 – There is a small piece of black plastic that maintains the top part of the motor unit (with the mirrors) on the left side of the board. Twist it and remove it.
4 – Pull up the mirror part.
5 – Be careful during all that not to touch any of the mirrors or prism or whatever seems to conduct light. If you do, you can always clean with isopropyl alcohol or glasses solution.
6 – Put some sewing machine oil on the shaft. Juuuust a little. I used machine oil SAE 20 or 40 (not sure – I didn’t look). WD40 would probably work also. Again, not too much – wipe the excess.
7 – Put everything back together.


That worked very well for me and my HL-1670n is back to his nice purring noise.

Good luck.

Can u please tell me Error E51 and the possible solution to fix it

thanx
by sumit on Sep 8, 2006 at 6:21am Add comment
Sorry never got that error (E51). I suspect a misalignment within the laser path. You could open the laser unit (as describe above), clean everything (mirrors and lens) and make sure that the shutter is moving freely (it should open when the printer cover is closed - on the left side, the lid should push open the shutter lever of the laser asembly).

Hope that helps.

I replaced the fuser drive gear, and turned the printer on, and got and error 54. I found the main motor connector had come off, so I plugged it back in and I am still getting the E54 error.
After warm up I can see 3 low pulses on pin 2 and 3 high pulses on pin 8 of the DC motor connector. After the 3 pulses the error is diplayed.
Does anyone have any suggestions on what to try.
Thanks Jeff

The described fix of oiling the motor shaft worked great for me. Thanks for taking the time to write it up!

I would suggest a couple of changes:

3 – The lower/right screw also maintains in place the second connector going to the unit. Remove it and unplug (pull) the connector.
4 – Squeeze out the laser unit from under the wires (going back and up).

I found it easier to remove the single screw for the small circuit board in the bottom right, and then take the laser unit out towards the front.


3 – There is a small piece of black plastic that maintains the top part of the motor unit (with the mirrors) on the left side of the board. Twist it and remove it.

I did not find it neccesary to remove the black piece. Simply twisting it 90 degrees was suffcient to remove the mirror assembly.

Same error different results, I took everything apart sprayed WD40 onto a clean towel then cleaned the shaft and its entire area, also there was some corrosion on one of the coils [where the shaft goes into, on the circuit board, but i cleaned it up pretty good, Still got Service Error Code E52, When I pressed the SET & Minus KEys it displayed: SCANNER MALF
Any one seen this before?? fixed???
Thanks in advance
by ThomasDean on Oct 19, 2006 at 8:52am Add comment
I don't know what the heck you're lubing with that WD40, but you're not going to fix anything. The 52 error refers to scanner motor rotational speed. It's either spinning at the wrong speed or not spinning at all. You will have to replace the laser scanner assembly.

ok,
which piece is the Laser Scanner Assembly?
how much is this part?
thanks
Tom
by ThomasDean on Oct 23, 2006 at 8:54am Add comment
Oiling of the laser assembly motor shaft does work. Note however that sewing machine oil is more appropriate then WD40. It helps the motor getting to its necessary scanning rotational speed (less friction). If the symptoms are error E52 and a strange noise coming out of the laser assembly then this procedure should fix it (for a time at least). The noise comes for the vibration of the rotating mirrors that looses it rotational angle, putting a fine layer of oil between the shaft and its enclosure will do it. Might work if there is no noise but if the mirror doesn't spin at all, well... that's another problem of course.

Hi

I too have a 1870N which has died in similar fashion

Are the steps to fix the 1870N the same as for the 1650....

Would be really grateful for your reply as my printer has done less than 15000 impressions - Anonymous
I have an HL2070N and had this problem tonight - while printing very important banking information, which I had already closed the screen on the PC for. It was very important not to lose this information, so I could not turn off the printer as I would lose the data from its internal memory.

after 10 minutes of pressing the go button and getting angry, I gave the printer a good hard hit, pressed go, and away it went. has been printing again all night no probs :)

by ex engineer on May 17, 2007 at 4:52am Add comment
This worked for me on an HL-1670N as well. Thanks for the directions. I'll repost them here with my modifications [in brackets]:

Step-by-step instruction:

1 – Remove gently the top cover of the printer ( 4 screws – 2 on top/front + 2 in back/side). [Front screws are revealed by pulling open the front cover.]
2 – Be careful with the connectors going to the top LCD panel. You might want to disconnect the shorter one. [Do disconnect the shorter one.]
3 – Remove the laser unit located on top of the printer covered by a steel plate.

To do that:
1 – Unplug (pull) the white flat connector going to the left side of the laser unit.
2 – Unscrew the 3 screws keeping the laser unit in place.
3 – The lower/right screw also maintains in place the second connector going to the unit. Remove it and unplug (pull) the connector. [This was untrue for me.]
4 – Squeeze out the laser unit from under the wires (going back and up).
[This would not have worked for me, because of a permanently wired cable that went tightly over the unit. Instead, I followed another poster's suggestion and took out the one screw holding the small circuit board in place.]

You now have the laser unit outside of the printer.
1 - Remove the steel plate of the laser unit. There is a plastic shutter that will come loose. Don’t loose it and take note of its location in case you need to put it back. [I did not see any shutter, nothing came loose.]
2 – Unscrew the 4 screws maintaining the motor section and remove it. [This is not necessary. Leave the board in place.]
3 – There is a small piece of black plastic that maintains the top part of the motor unit (with the mirrors) on the left side of the board. Twist it and remove it. [Twist it 90 degrees is sufficient; no need to remove it.]
4 – Pull up the mirror part.
5 – Be careful during all that not to touch any of the mirrors or prism or whatever seems to conduct light. If you do, you can always clean with isopropyl alcohol or glasses solution. [Since you have to touch the mirror to lift it, I just cleaned it routinely with an alcohol prep pad after I replaced it.]
6 – Put some sewing machine oil on the shaft. Juuuust a little. I used machine oil SAE 20 or 40 (not sure – I didn’t look). WD40 would probably work also. Again, not too much – wipe the excess. [ONE drop of lightweight machine oil. I would advise against WD40, it is a penetrating oil and may not be appropriate here.]
7 – Put everything back together.

I'm glad I posted my instructions...

Two+ years on, and I get the same error message. This with less printing duty than prior to the first repair. I did the same fix, following my own directions, and it's working again. However, I'm thinking this printer is near its end of life. Bought in 2001, 8+ years service is really not bad.

Thanks to anonymous for the detailled instructions. Follow the second instruction set the one with the [] brackets. Just my 50c:

Attention: The mirror unit is actually the Hexagon plate itself!!! When lifting the unit use an optical cloth in order not to smear the reflective coating with fingerprints or scratching it with an unsuitable tissue. So what you want to lift is what you don't want to touch. Using an optical cloth to lift the mirror unit will reduce affection of the mirror unit to a minimum.

My printer was working fine until there was a paper jam. I ended up turning the printer on its side to clear the jam and when it was back upright I got an ugly noise and E52 error.

My laser motor was actually stuck - I had to twist really hard to get it to move at all before I could pull the polygon mirror/rotor out. So I cleaned the shaft and bushing with isopropyl alchohl before lubricating the shaft with a drop of light machine oil and replacing it.

It worked like a charm! Thanks for the instructions.

So I got this error and went diving into the guts of my HL-1650 to do an emergency lube job on the polygon motor shaft. (Not as dirty as it sounds.) When I started the machine back up, it whined angrily, but printed. Now I've found a part I seem to have left out, which I think is the "plastic shutter" mentioned here. It's a spindly thing, a right angle of narrow black plastic maybe 2-3 inches on a side, with an upward (downward?) jutting narrow flange on one end that goes off along the third axis for an inch or so.

Where the heck do I put this, and is it related to the angry whine?

Also, when I got to the polygon mirror, there was a bit of hard goo stuck to the top. I wondered how it had gotten there but decided it should probably come off, so I cleaned it up a bit. Now I'm wondering if that was there purposely as a tiny weight balance to make the motor spin smoothly (and QUIETLY) at high speeds. Did I mess up? If so, can I fix it?

Thanks for any help.

Hi,

I tried this fix, following everything to a tee, but when I booted up the printer, there was that noise and the "Error E52" again. I don't usually do things like this so after putting the printer back together (took me about 45 min) I was ready to be proud of myself, but instead I was really disappointed. I rebooted the printer four times. Same result :Error E52". BUT, on the fifth try, it booted up just fine. Whew! Now I am printing again. Thank you so much. BTW, I didn't have sewing machine oil, so I used some 2 speed chain saw oil.

One suggestion...

After a careful but thorough cleaning of the bearing shaft, I used a light coating of white lithium grease on the bearing shaft. It does a better job of standing up to heat and friction than liquid based lubricants.
by Anonymous on Nov 29, 2008 at 10:30pm Add comment
I would only say that you should use a thinner oil to lubricate your scanner unit. The lube that you used is more for feed roller shafts, gears, and parts of the fuser. that piece is very sensitive to friction and still you might incounter problems down the road becuase of it. I guess if it worked then go for it but just my personal advice to people still reading this post.

I did what you recommended to do but it is not an obligation to unscrew the 4 motor unit screws, only turn the black plastic rotor retainer for 90° and the rotor/mirror unit comes up !
half of the half of the half drop sewing machine oil in the brass bearing at that's all !!!

Regarding section 3, step 3 - "There is a plastic shutter that will come loose. Don’t lose it and take note of its location in case you need to put it back."

This is same piece of plastic that MiracleFlop noted, I believe. I'm having the same issue ... the piece basically fell away from the unit before I had the chance to properly see where it goes or how it attaches. There is nothing obvious that I can discern. It looks like it actuates a lever outside of the laser unit but it's unclear where to position it. Does anyone have further information on this piece?

:::UPDATE::: I just found the slot where this piece goes -- to the left of the hexagon mirror, there is a depression where the part rests ... the swing arm should be positioned on the outside lower left of the laser unit, while the rest of the piece is inside, held in place by two circular-shaped molds -- one large and one small. There's only one way it fits in, so it's impossible to mess up once you find the correct location.

AND the printer is up again working like a charm.

Very helpful thread, THANKS!
by gdguru on Apr 28, 2009 at 4:35pm Add comment
I have the same problem with that plastic shutter. However, I may have a different version of the laser as I can't see any circular shaped molds. Could you send a photo by any chance? I just can't figure this out.

Pretty much the E52 is a scanner motor error. Most likely due to wear. You could try reseating connector P12 on the engine PCB or check that 24vdc is going from pin 1 24vdc to pin 2 GRD. If reseating and verifying 24vdc then replace laser scanner. If not you could go further and test the power supply output to the engine PCB. Most likely though your laser scanner just went out. You could also unplug from wall and let it sit for around a half hour to hour and try again. Usually when the motors start to go the machine gets real noisey so if you noticed that lately then thats another sign. Some people on this site fix noisey or failed scanners by lubricating the scanner motor bushings. Light synthetic oil. NOT wd-40. Look through post above for tear down instructions.

I have had our HL-1670 for some years but it's backup printer and not had much use at all. I just can't believe that this unit would be suffering from "wear" as it's only on it's 2nd toner cartridge ever! Upon disassembly the motor seemed to spin w/o any noticeable drag, etc. Nevertheless, I lubed the shaft sparingly with some NyOil (great thin film synthetic lube) and the problem seems to be resolved. So thanks for saving me $200, plus labor fees :) - unknown

Hey guys, I just fixed my brother printer. It had a screaming sound and my model gave me error code 71, The problem was that the polygon motor needed oiling that's all! You have to split the printer to pieces and get to the part where the laser is. Be sure to use a paper and pen and mark where all the cables go and screws so you can put it back together properly. When you get to the part where you open the laser unit. The polygon motor which is basically a bunch of spinning mirrors, that thing needs to be pulled upwards. There is a plastic notch holding it, you can rotate that 90 degrees and pull upward on it. No need to take any clamps off or anything, pull upwards, its held by a magnet. Then just apply a small amount of grease to the shaft area. Lithium grease is a good idea. I used cooking oil, probably not the best idea. WD-40 probably is a bad idea too. Then put it all back together. Do not run the thing with the laser part open. You don't want to get the laser shined in your eyes, that's all bad. Its a small laser beam too, so it may seem invisible. Clean the mirrors! Do not touch them as much as you can. Clean with alcohol if it gets dirty.

Many thanks - once I found out where the noise was coming from, Google brought me here and it's printing again.

Happy New Year!

I finally found where the part goes! gdguru's explanation is good up to a point. For some reason, I thought the part went underneath the laser unit. Because I turned the unit over when I took the cover apart the first time, I didn't realize the part came from INSIDE the laser unit. Once you make this clear, gdguru's explanation works!

Five years after this thread was started and another happy camper is added ! My HL-1650 gave me the E52 error (and the accompanying horrible sound before dying) and I was all set to drop it at my local shop. Found this thread and followed the instructions (the later set with additional bracketed tips, thanks LiamH! ). 30 minutes later -- working perfectly!

BTW I used 1 drop of Singer "All Purpose Machine Oil" - purchased at my local sewing supply store (JoAnne's Fabrics on Riverside in Sherman Oaks, CA)

I used a microfiber glasses cleaning cloth to handle the mirror. CLeaned up a bit with a can of compressed air while I was in there. Everything purring like a kitten.

Thanks everyone.

Thanks so much! Model HL-1850 - I started w/E52, and then followed the provided instructions. Next I got E51. It took 3 times to meticulously clean the mirrors and prisms w/rubbing alcohol and voila!! READY! It took some patience but very well worth it. I took the printer off the hands of a client who did not want to wait for a repair. So I’ll see if she wants it back, otherwise I have a new-to-me laser printer, and lots of satisfaction to boot!

Yet another printer fixed. My HL-1650 started making more than normal noise about two months ago. Just recently it would sound like the motor would freeze up on start up and trip the E52 code. The instructions here worked great and the repair was much easier than expected. I used some Wahl hair clipper oil as it was the closest thing to a light oil that I had on hand and the printer is back to normal, much quieter! I must say this has been a great printer, I have had mine for about 8 years if my memory is correct and have never had any issues with a page count of 17,989 on the printer.

Thanks to the folks that posted the fix many years ago.

Outstanding!

The compiled & bracketed instructions covered my HL-1650 printer perfectly.

Even if I have to do this again, easy-enough to keep my trusty Brother printer in-the-game!

Thanks to everyone's contributions.

Well, a year after success with the E-52 fix detailed here (singer sewing machine oil did the trick) and the E-52 error has returned, with noise and all.

Sadly, the fix didn't work this time around, even after several tries. Perhaps something else wrong with the laser unit?

So, decision time -- I found a replacement laser unit (PART # LJ5604001) from sparepartswarehouse dot com for $136 plus shipping. Pretty confident that I could put this in, after doing the tear down so many times. But like an old car, is it worth putting $ into an old printer? Who knows how long before the paper drive goes, etc?

Replacement would probably to be a new HL-6050D which would run about $400. (Not interested in the lower priced HL-5370 -- the build quality seems so cheap, and my solid 1650 has lasted almost 10 years!)

Anyone have thoughts on the fix up vs. buy new choice?

I very carefully followed these instructions and it worked! Thank you, I now have a working Brother HL-1650 for the low, low price of 30 minutes or so of my time and a single drop of oil. Oh, and the tiny bit of alcohol to make sure the hexagonal mirror on the motor was clean.

Thank you, thank you! I thought I was going to have to spring for a new cheap Samsung or some such.

Hi all, I just followed the instructions and it worked (sort of), the noise is gone but now my pages come out blank! Any ideas on why this is?

Hi All,
I just had E52 show up on my HL 1650 for the first time and my machine was purchased in 2000. Might try repairing it but as someone earlier suggested it might be time to get a new one. I see laser color all in ones for about the price I paid for the 1650. But at the same time it could be fun to try to repair this one.
Thanks for all the insight above.

I had a very noisy screechy polygon motor. After disassembling the printer I found that the motor easily spun when moving it with my finger.

It must have been having trouble at high RPM (that's why the screeching noise was happening).

I applied a couple drops of 3-in-one multipurpose oil to it, and tried it out.

The motor began to spin and then immediately SEIZED! Now I can't even spin it with my fingers anymore.

The 3 in 1 oil probably wasn't a good idea.

That's ok, I'll feel more confident replacing the motor with a new one anyway.

Just wanted to share what happened to me.

The procedure seems to have done the trick for me. I'll reserve final judgement till I've cycled some jobs through it, but it looks promising.

Thank you to all who posted solutions.

Used RemOil for lube.

Twenty minutes, that includes complaining on Facebook and posting photos that my workhorse 1650 has died and I was 'going in'. Twenty minutes and I was done!

Thanks to Anonymous for the steps, what an easy fix!

Tools needed: Phillips Screwdriver, Needle Nose Pliers, Lint-free cloth, cheap 'drug store' Isopropyl Alcohol, Lubricant (I used Silicon Lube, the kind in a tube that looks like a pen, and fits in your pocket.

Anonymous's steps, with Liam's additions and my additions too.

Step-by-step instruction:

[Remove Toner, paper tray, duplex tray from back. Unplug the unit. Find a nice flat surface to work on. You're looking to do this in a clean dust-free place. We'll be messing with the optics!]
1 – Remove gently the top cover of the printer ( 4 screws – 2 on top/front + 2 in back/side). [Front screws are revealed by pulling open the front cover.]
2 – Be careful with the connectors going to the top LCD panel. You might want to disconnect the shorter one. [Do disconnect the shorter one.] [I disconnected the other cable to the LCD too so that I could place the top cover off to the side. I'd recommend it, if you destroy a wire or connector you're SOL!]
3 – Remove the laser unit located on top of the printer covered by a steel plate.

To do that:
1 – Unplug (pull) the white flat connector going to the left side of the laser unit.
2 – Unscrew the 3 screws keeping the laser unit in place.
3 – The lower/right screw also maintains in place the second connector going to the unit. Remove it and unplug (pull) the connector. [This was untrue for me.] [Me too, keep it plugged in]
4 – Squeeze out the laser unit from under the wires (going back and up).
[This would not have worked for me, because of a permanently wired cable that went tightly over the unit. Instead, I followed another poster's suggestion and took out the one screw holding the small circuit board in place.] [Circuit board method is the way to go, unscrew that for a little extra play in the wires]

You now have the laser unit outside of the printer.
1 - Remove the steel plate of the laser unit. [It's on with clips, pull the plate cover from the black plastic clip on the back right and front left. There is a plastic shutter that will come loose. Don’t loose it and take note of its location in case you need to put it back. [I did not see any shutter, nothing came loose.] [I had the shutter come loose on me, it's a little see-saw in the front left of the unit that looks like it blocks the laser signal. Just be careful removing the plate but you should be able to figure it out if you need to replace it]
2 – Unscrew the 4 screws maintaining the motor section and remove it. [This is not necessary. Leave the board in place.] [I removed it but yeah, you don't have to. If you choose to remove it you can pull the cable into the housing gently and unplug it so that you can work on the motor board itself.]
3 – There is a small piece of black plastic that maintains the top part of the motor unit (with the mirrors) on the left side of the board. Twist it and remove it. [Twist it 90 degrees is sufficient; no need to remove it.] [It's the Tetris 'L' looking part, twist it to the right or left gently with your needle nose pliers and then gently pull up on the mirror to release it.]
4 – Pull up the mirror part.
5 – Be careful during all that not to touch any of the mirrors or prism or whatever seems to conduct light. If you do, you can always clean with isopropyl alcohol or glasses solution. [Since you have to touch the mirror to lift it, I just cleaned it routinely with an alcohol prep pad after I replaced it.] [The EDGES of the six-sided metal plate are the mirrors. Clean them good but only after oiling the motor]
6 – Put some sewing machine oil on the shaft. Juuuust a little. I used machine oil SAE 20 or 40 (not sure – I didn’t look). WD40 would probably work also. Again, not too much – wipe the excess. [ONE drop of lightweight machine oil. I would advise against WD40, it is a penetrating oil and may not be appropriate here.] [I wouldn't do WD-40 either, I used silicon lubricant. I coated the shaft, wiped the excess with my fingers and worked that back together. Up, down, in and out. Twirl the motor so it gets a good even coating. Pull it back out again and put another light coat on it, wipe again and re-assemble.
7 – Put everything back together.
8 - The printer may remember the error code so a power down or two may be necessary. It also seems like the motor takes a print or two to start evening out, so it may be noisy a bit. You may also get dirty prints, print a few DEMO pages and you'll be fine.

Thank you all very much for posting those detailed instructions to fix the E52 error! My old and beloved Brother DL-1650 is now running like new again after following this more then twelve years old thread.

However I made a minor modification of step 2 of part one in the "Step-by-step instruction:

Instead of disconnecting any of the cables going to the top LCD panel, I removed the part of the top cover that holds the LCD unit by unscrewing the 3 screws that holds this part. The screws are accessible from underneath och the top cover.

This might help to reduce the risk of destroying a cable or connector to the LCD panel.

Thank's a lot
and a happy new year from Sweden,
Kurt
