HP RM2-6418-000CN Repair HP Color LaserJet Pro M452dn M452DW M377DW M477FDN Fuser

Great video and very helpful, BUT! It needs either audio or captions. At the 7:30 mark, when installing the plastic part that caps the black tube, if you don't have it aligned just right, you WILL rip the tube when snapping the piece on. No second chances there. Then at 11:25, when installing the large white connector, care needs to be taken as the terminal in the strip can be sticking out a touch, and simply pushing the connector on will once again, put pressure on that thin black tube. lastly, one that drove me nuts is at 11:37, when reinstalling that shaft, the eccentric on it also has a pin in it. If your not careful, it will fall out while the shaft is on your bench, and you will go nuts trying to figure out where it goes! However, I wouldn't have been able to do the repair without this video so thanks for making it!!

I'm glad I found you doing my exact model. But I should warn others that you cut out some pretty key pieces being disassembled while making the video short.

Trying to salvage a M452dn fuser with crumpled paper down inside the fuser. This looks like it might get us to where we could remove the 'accordian' paper, but there's no commentary on what you're doing so it's hard to follow what needs to be done.

[@promisekheeper7119]

After replacing fuser sleeve on m477 it doesn't burn at all, you can clean off prints on the paper easily.. any idea what could be the cause?

[@dermarius87]

Yes, did that repair many times, no success yet, the aftermarket pressure rollers are way to bad, have tried many suppliers, wasted a lot of time and money, but haven't had any luck... The thermal conductivity of them is just too bad... You can just set paper thickness to high, wich will reduce print speed, but will give the heat element more time heating up the roller, it will print just fine than but at somewhat half the print speed... Some people state, that after 500 pages or so, the roller is burned in and will run rust fine then without reducing print speed / changing paper thickness... Haven't tried that yet, still searching for an out box working spare part 😔

Excelente video gracias por la información, Saludos de Argentina

[@dirkloons180]

Great video ! I had marks on my prints because pressure roller was peeling of on one spot. I replaced pressure roller from my fuser thanks to this video. All prints now have spots and duplicates of text between the required text. Any idea what could be the cause or solution?

[@stevethompson2566]

Same thing happened to me.

[@jaja37]

Is there a specific position for the fuser to put it in before re installing it in the printer ? There are two positions : first one, the roller is free so it is easy to make it spin... second one, the roller is hard to make it spin (with fingers) because of the pressure of the 2 springs. First or second or ... it doesn't matter ? Thanks

[@dermarius87]

Doesn't matter, the printer recognizes the position while switching on

Hallo Hans-Peter, wo hast du die Teile bestellt? Ich habe die Reparatur schon unzähligen male durchgeführt und unzählige Druckwalzen / Pressure Roller getestet... Die thermische Leitfähigkeit ist leider bei allen bislang viel zu schlecht, das Tonerpulver wird nicht fixiert... Eine Möglichkeit ist es die Papierdicke auf hoch zu stellen, dadurch verringert sich die Druckgeschwindigkeit enorm, so hat die Druckwalze mehr Zeit aufzuheizen und fixiert dann auch sauber, aber eine dauerhafte, geschweige denn kommerzielle Lösung ist das nicht 😔

[@naijomo5184]

Well done, Great presentation video.

Parabéns amigo, ótimo vídeo. Brasil ...

i succesfully disassembled and re-assembled the fuser using this guid however the noise that i was getting is worsened. the printer prints but with noise. i don't know where to look at for this noise. any ideas?

[@tristaninosanto7544]

Same thing with my printer after I replaced the lower fuser roller.

[@dermarius87]

@@tristaninosanto7544 you can be lucky if it's only the noise, in general the toner will not be fixed to the paper after replacing the pressure roller... Changing the upper sleeve makes things even worse as both aftermarket parts have way to bad thermal conductivity, I'm still searching for working replacement parts... 😔

[@simplybs9311]

Hi when I put my fuser unit back together I began getting creases on the page, what could be the cause of that?

[@twosnjuk]

This was great ... I have a roller that started to peel off ... This will be a better route to try. I found some roller for about $30 ... better than $300 for the fuser.

[@cipibebe]

Have you replace roller? you don't have problems like smearing, spots toner on paper? please post a link where to buy if works good, thx

[@mevlutkaya5826]

I changed press rollers, but the printer shows engine communication error, why?

[@musanganga125]

quicker method...awesome.

i am a computer guy. disasembling a laptop is nothing compared to this printer
