Question about Xerox WorkCentre XD125F All-In-One Laser Printer

1 Answer

Xerox XD125F I have taken out the fuser assembly. I was expecting to see broken teeth on gear. I didn't. However, when I tried to gently turn the gear it would turn hard and didn't seem to be connected to the light brown tube (?). Should it turn the light brown tube. It seems logical that it would. I definitely heard a small something drop out when I removed the fuser assembly. I expected it to be small teeth...but it wasn't. I am not sure what fell...but I can only imagine that it was something that connected the gear to the small tube...a compression type ring? I am trying to avoid buying a $200 full assembly. Can I replace just the broken part? What steps do you recommend next?

What you can try is just replacing the fuser drive gear and the bushings on the heat roller.
That small tube your relating to is the heat roller. The plastic like busings are really tight not allowing it to move freely.
Not the easiest fuser to rebuild to be honest. You will also want some high temperature lubricant to use on those bushings and also on the pressure roll shaft to make that roller run smoother.
Clean it well and be sure it is running free.
You need to look at the heat roll and presure roller carefully to check for wear and grooves. If they are worn, you will be better off replacing the fuser then trying to rebuild it.
I will provide you the link to an excellent parts source, click on parts then the scroll down tot the XD125, They have about everything you want for that fuser.
If you call ask for Britt..

Where is the fuser located on MXC 311


Hi,
The fuser unit is located in the right hand side of the machine. If you open the right door, inside the upperpart of the machine you will see 2 grey handles, 1 towards the front of the machine, the other towards the rear. If you pull these handles out you can then remove the fuser unit. There are 3 known faults for loud fuser noises,1 is the fuser drive gear inside the machine strips the teeth on it, second, the main drive gear in the rear of the machine strips the teeth(usually caused by the 1st problem getting broken teeth stuck in the remaining teeth causing the drive motor to strip the main drive gear) & thirdly, the pressure release mechanism breaks on the fuser unit itself. If it is any or these then unfortunately you will need the assistance of a dealer to replace the damaged parts.
Hope this helps.
Dave.

I have a ticking-clicking sound coming from the top rollers of my HP4+ rear exit assembly?


Hello,

The ticking sound you are hearing is most likely a broken part called a Fixing coupler. This small gear is what drives the fuser assembly and the output rollers. To check this you ill need to open the back of the printer and remove the fuser assembly, there are 2 screws in the middle of the printer, unscrew and pull the fuser out.
buddymc_3.jpg

The fixing gear can then be seen behind where the fuser was on the left side. You will see a small gear about 3/4" around. Rotate this gear and look for broken or missing teeth. We repair printers in our shop and when we get Laserjet 4, 4+ or 5 series printers in with clicking or grinding sounds that is almost always what the issue is. The Fixing coupler is part RF5-0350 and is available here: http://www.ccl-la.com/catalog/product_info.php?cPath=24_41_48&products_id=125

It takes about 20 minutes to disassemble the printer to get to the fixing coupler so you can change it out. Well worth it if you do the work. A repair shop will probably charge you $75-100 plus parts to do the same thing.

I hope this helps, if so please rate my solution.

My HP Laser Jet 4 makes noise when I turn it on, but it indicates Ready. What could be causing this?


Hello,

This sounds like you have a broken part called a fixing coupler. To check this unplug the printer, now turn the printer around so you can see the back side. Open the fold down cover. You will be looking at the fuser assembly. There are 2 screws that hold the fuser in place, remove them and pull out the fuser assembly. Now look inside the printer on the left side behind where the fuser was located. You should see a gear assembly. This is the fixing coupler. The small gear that is closest to the rear of the printer is the one that breaks and caused the issues you are having. Look over the gear and check if it has broken teeth. You can turn the gear by hand to look all the way around and see all the teeth. If you do find the gear is broken then you will need to replace the assembly. The procedure is fairly simple, if you can use a screwdriver then you can do the repair. We carry this part in stock and you can contact us at [email protected] if you need more information.

I hope this helps, if so please rate our solution.

HP Laserjet 4100 series , paper jam output tray.( on top of the printer ). The roller under the topcover is turning the wrong way. The paper can't get out of the printer, and jams between the upper roller...


Hi F_bulsara,
First thing to try is to flip the paper over in the input tray. There are 2 sides to paper. One side may curl a bit too much due to heat of the fuser and get caught near the output rollers.

Unless the Output Assembly was assembled wrong, it is impossible for the rollers to turn the wrong way. The gear in the fuser drives the output assembly. The top rollers are rolling out.
If the rollers are not rolling, then one of the gears must be broken or missing. The output rolllers might need cleaning.

Next check the fuser unit. Disconnect power to printer and turn printer round. Remove the back output tray and the two small covers (left and right). Undo the 2 screws that hold the fuser in place. Pull the fuser out. Check the gears on side of the fuser. A broken gear in the fuser could cause this problem.

Rebuilding the brother fuser for the intellifax 4100


Although it fit the broken fuser, it does not mean it's ok.
1-they must have the same number of teeth ( diif. gears have diff. amounts of teeth)
2-it must be the same diameter ( so they can mesh together, otherwise it's touching the tip of hte teeth and may be skipping.

But I'm not sure the double image is coming from there, it would jam the paper because the timing is off.
Anyway you need to eliminate the obvious then see what happens, I think you said you had another tonertry putting that in, if it doesn't work then change the gear for the correct one.

Paper jam problem in laser printer 4100


if this happens every time you need to replace the fuser. but there is a possibility it could be the main gear drive assembly, 9 times out of 10 it's the fuser. a gear on the fuser usually breaks a few teeth. the fuser is very easy to replace and is a part that will eventually need replacing on all printers.
