I am having the same issue. Bought new toner thinking it was the cartridges. But new cartridges did not resolve the issue. HP really should be responsible for this service. There is no way a 500 dollar printer should have this issue with less than one year of service. Thank you for sharing the disassembly process
Bilal, thank you my friend! You have saved our printer from the landfill. Once we had it apart we took the mirrors out completely by removing the metal clips, wiped each with isopropyl alcohol, dried with micro fiber wearing gloves to prevent finger prints, cleaned all the plastic lenses and reassembled. print quality returned to acceptable levels, but still was not factory new and it bugged me enough to rip it apart again a few months later... this is when I noticed a critical step missing from your tutorial.
This time i noticed the metal square and motor assembly in the center was also quite contaminated with dust and film. I cleaned that square motor - some models I've seen videos on are hexagonal but particularly the edge of the metal on top which shined to a mirror surface after we cleaned it and BOOM printer is back to it was like day one. I was ready to replace the laser component and ultimately the entire printer but this video has helped me save it!! hope my additional tip about the motor edge helps others! keep fixing things!!!!! and sharing the knowledge gained!
thanks again be well
Any chance you could upload a video of this additional step?
Is it the motor shown at 7:26? Attached to the logic board connected with a yellow cable?
Same here, after cleaning that square mirror on the motor, BAM - magenta missing 🤣
Misaligned one of the mirrors 🫣😅
But yeah, BOOM, perfect printout again, thanks for your comment on that.
PS: don't try to remove the laser PCB to clean the diods, did that on another HP in the past, it's pressed in and will die if you try to remove it 😱
@@dermarius87did you find solution??
@@MohamedAdel-f5g yes, just clean the edges of the square mirror on the motor and align the mirrors correctly if you've disassembled them for cleaning 😉👌
I am sorry I doubted you, my friend- I followed your video step by step and my printer works again. Thank you, thank you!
Glad it helped !
Bilal, you are amazing! I have this EXACT same issue! I will be doing this repair this weekend! Thank you so very much!! 🙏🙏
All the best
Nice informative video!!
I tried the same steps, glass was very smoky, I cleaned it but still print quality is not good. Toners are 90% full
Is there any other steps you suggest? Thank you
bilal , i tell what, you just made my day. may Allah bless you
learned something today and i saved a lot of money, honestly , i was willing to take my printer to a maint shop, and they will charge me some where around 450 to 550 SAR
but i knew, i could to it myself, i have electronic background and i have the guts
so, your great video got me what i want
keep it up man, thank you very much
All the best sir

I followed your great instructions to the letter. I found cloudy ares on the mirrors and cleaned them well. Quite clear now. I reassembled the printer and the result was no better. I was very surprised since the mirrors were so much better. Is there a laser lens
I should have cleaned too? Any other suggestions?
Yes laser lens should be cleaned and all mirrors as well, and further more check your toners cartridges also
@@BilalKhalid I did not see where you cleaned the laser in the video. I have installed HP toner cartridges. So it must be something I missed cleaniong in your opinion. Do you have an image of the laser area I should clean?
I dont want to damage anything by doing it incorrectly. Thansk for your help with this!
In center of the laser unit there is one square shape silver part where the laser beam hit and spread around , clean this square part well
@@BilalKhalid That fixed it!!!!! Thank YOU!!!!!!
Thanks a Lot, Bilal. I have been triing so many things since 6 months and nothing helped. Now after your workshop the printer is working again.
Glad it helped
Thank you Sir, this helped a lot, and is printing the way it should.
worked like a charm, my color was still there but super off, I cleaned it as per your manual and no printing like new!
That is perfect. Mine is doing exactly the same thing but couldn't find a sound engineer to fix it. It is a pity that we are not in the same region.
Glad it helped! where you from dear?
Hello Bilal, is this way can occurs also for my HP LaserJet Printer Pro 100 M175nw ? I have replace the imaging drum unit, but it was not solved. The result was still degrades and not clear/light especially the black color at the center of paper it was very light/faded/fainty and not strong at all even every color. I mean, is it because of the laser unit block need to be cleaned?
ruclips.net/video/duhVeo53shA/видео.htmlsi=dIKprGvBqN-yNboL
Check this video if the print is faded on the middle of the paper
Awesome. This worked to perfection!!! My colors all came out better. Thank you!
Glad it helped!
Sir , very nice information, colour dots magenta colour dots coming while taking black print m479fdw printer, I am using refil toner , is there any solution , please update , thank you.
Bilal !!! Many thanks for this VERY informative video !! My case, HP M283fdw from heavy cigarrette smoker residence. Super light print out on supply printout.
First attempt, fail. Second attempt, I cleaned the square mirror motor. !!! Success !!!
Glad it helped
I have a m255dw. Did this and watched another video on cover removal. Problem remains. Any other thoughts on what it could be?
I just purchased the M277dw at an estate sale 8/4/23. It fired right up and connected to my wifi and printed Black and White fine but it would not print color well at all. The prints were very dark and undefined. Also if I set the media to plain paper as is in the printer and then slid the quality to high it would make the sound of paper acceptance but then would stop and just reveal that the printer was thinking - for 10 minutes before I gave up. Beings it is 3 times the price new ($1300) of my M283cdw ($430) it should be worth the fix. But. Id like to know where I can have it done as I would not attempt this myself. As I only paid 45 for the printer with 2 full cartridges I think it would be worth it. The new HP cartridges were themselves worth $200. ( I haven't yet tried the copier or scanner )
Hello I'm from Brazil.
I fixed the Solenoid on my HP CP1525NW printer, then I opened the Laser Scaner and the Belt, I cleaned everything, it was perfect. But then after a few days CYAN no longer prints. I suspect it is the Laser Scanner. I'm going to do the cleaning again and hope that everything goes back to normal, so I don't have to buy a new Laser Scanner. I'll let you know if it's resolved. Hug.
All the best bro
@@BilalKhalid Thank God it worked, CYAN is back to printing!!!! I managed to fix it. I disassembled it to the Laser Scanner, cleaned all the mirrors and acrylics with cotton and cotton swab, without any alcohol, really dry, very carefully including that square with the little motor and that's it, All the colors perfect!!!!! Thank you very much for all your attention. Ahh and in case anyone really needs to change the Laser Scanner, it's the RM1-4766, I took a photo of the original that has the code. Thank you very much for the video.
Que tal Señor, conseguiste solucionar el problema del color que no imprime, tengo problemas con el color magenta, si me podias ayudar por favor. Gracias.
@@juanchybenitez3086 Siii yo a echo una limpeza en Laser Scaner igual al video, y volvio a imprimir mi color Azul que no salia nada, pero ahora esta perfeita mi impressora. Espero que ayude. Perdon mi portuñol, soy de Brasil.
Thank you, very good 👍
From Riyadh.
Where is your shop?
Glad it helped! From Riyadh
After I put it back together, it wouldn't turn on. Did I not put all the connections back firmly enough?
I cleaned just what you did and it didn't fix it though. Thanks though. I can't get my side on the left correct so I have to leave it off. Think I'll be getting a new one.
Hello I have an issue with my printer (ECOSYS P6035cdn)
the printer is starting but the light on the dash board will not on.
do you have an idea on such issues
Disconnect dash board cable from main board and connect again then check
I did the same steps and the color came back more intense, but the black color has disappeared!!! Do you have an idea what happened or what I missed!!
it suppose to be fixed all colors if you didn't mess with the mirrors, and make sure with another black toner and check..
Sir I have this same hp, the black print is readable but the quality is not sharp, can that effect still be the laser?
Very complex with all of the screws and connections. Don't know how to keep them all correct for reassembling. Also, what do you use on the q-tips for cleaning? I could not hear...
Can you tell me what you said starting on 7:28 concerning the q-tips? Thanks!
Cotton buds. Clean the mirrors with the help of cotton buds. Thats it!
@@BilalKhalid Okay, thanks!
@@aleneb.4227 after cleaning is now showing me error 51.23, what should I do?
@@Godsloveferdinand cable connection error. check the cables.
I have printer hp m575 and it has the same issue after i changed the ink
Can i do the same steps?
I have this issue too but the supplier status prints perfectly but all other prints are light. Do you thin it is the same issue?
Could be
first time i wrote a comment, ever. I thank u. u solved my problem. wow. best regards
Thank you for your time.
I have hp colour laser jet m283fdw I bought it second hand and bought 3rd party colour cartridges but it print blank or some times very faded hardly see anything on it .. do you think I need to do this process as shown in the video or look for something else first?
Yes clean laser unit if you think your toners are fine
I have done cleaning laser but not much improvements .. before it was almost blank but now it’s very light ..what can I do now?
Worked perfect for me. Thanks!!
Ayuda por favor, hice la limpieza, ya imprime pero menos el color magenta, QUE PUEDE SER POR FAVOR. GRACIAS
My printer, put too much yellow and I don't know why?
The edge of the paper print with yellow?
I cleaned all mirror, still having same issues ( still printing so light ) do you know what else could de ?
Did you try new toners ?
I have HP M477fnw and it’s printing pink background only when I print in colour. Black and white is all good. Any idea how to fix?
replace magenta toner. all the best.
@@BilalKhalid replaced magenta it didn’t make any difference. Any other ideas?
Will this work on my HP laser jet pro mfp m277dw?
Yes it will
Hi Bilal, I contact you, because I see, that you are an experienced engineer.
My HP Printer (m283fdw) stopped working with a laser scanner fault. I replaced the laser scanner and everything worked fine, but only for a few days. Than the magenta color disapeared.
The event log indicated an error with the density sensor. I replaced the density sensor, but still, the magenta color (100% full) does not print. I swapped the cartridge with another working cartridge (I have 2 times the same printer here). It is not a problem with the cartridge. I opened the laser scanner and cleaned all glases and plastics. But no success. do you have an Idea what I can do next? The service manual says, it could be a problem with the cartridge tray or the ITB, but that does not make sense to me, because all the other colors work fine.
The issue can be in drive that located on the right side of printer
Or it can be due to high voltage board as well
@@BilalKhalid Thanks a lot, I will check that👍
@@BilalKhalid I installed the HighVoltage Board in the working printer and Magenta is ok!. Though, it is not that board. I marked the drum of the magenta cartridge with a soft pen and verified, theat the roller turns. Though the mechanics on the right hand of the cartridge tray is verified to be ok. Do you habe another idea?
Finally the problem was the Laser Scanner Unit. But it was not dirt but a broken beam.
Thank you bro.
You're welcome!
My printer says it has error 13 after putting it back together. How can I fix this?
Please show how the print head can be cleaned manually
what is your printer model bro?
Great help. Thank you.
after cleaning it, is now showing me error 51.23, please what should I do?
best video ever
Bro hp cp1515n having same issue but the toner chips can't change during refill
Printer missing the color
toner memory chips have no concern with the quality of the print. the issue can be from toner drum or laser unit.
Wow. Thanks brother 👍👍👍
I did this, every single step, but it didn't change a thing. I even updated the firmware and restored the default settings. Still real light printing. What else can I do?
Try new toner cartridge
Did you clean the motor as well?
grinding noise during startup and poor color print on Color LaserJet MFP M680
grinding noise is normal in this model, and about print quality, did you check the toner? replace with good toner cartridge then check the quality.
i followed all the steps. and now, all the colors print on my test, but now none of the black show up on print. which is the complete opposite of what it was doing before i found this video. any suggestions?
Try another toner
@@BilalKhalid i just replaced all my toners! like i said, the black was the only one printing (albeit faint) before i cleaned the glass, now it’s the only one not working.
the issue can be with laser unit, you have to try with replacement of laserunit
Huge help, thanks Bhai
but how are covers removed?
search on that topic. i watched another video on that.
BILAL, So i was doing this, had it completed, and now I have an Engine Communication Error....How do I fix that>
Check cables, carefully . Might be one of the cable is not connected with high voltage board
@@BilalKhalid Think I made things worse. Now the display screen has no data showing, just the light.
Yeah, dont panic. Just carefully remove all cables including screen cable and connect again on correct positions
@@BilalKhalid Thank you I will try it a little later, I will report back with the results.
I have a hp color laserjet pro mfp m277dw I had a problem with the poor quality as well, I replaced all the toners and cleaned the bottom roller now the quality is the same, but when I try to print black and white, it leaves horizontal lines on the paper cyan yellow and magenta, they're very strong idk what is the issue
Can you please help me out ?
I checked the roller and it's dill of yellow power
No issue with the roller. The lines are due to the toner drums. If there is red color line then the issue is with magenta toner. If yellow line the yellow toner need to be replace.
@@BilalKhalid I have replaced all of them with new HP original toners and the same issue
Good video brother.
Mary pass ya printer hy but wo picture ko pinkish tone dy rha please mjy koi bta skta is ka solution
