The Components In The Fuser Assembly

Fuser assembly has a piece of fuser roller over the top side for generating heat, and a piece lower pressure roller to assist the upper roller to perform the final printing process which is to fuse and bond the toner onto the fiber of paper, that is to say, to fix the texts and graphics on the paper.

In addition to the pair of rollers mentioned above, fuser assembly also has other parts in it to complete the fusing process, such as fuser film sleeve, heating element, fuser thermistor and driving gears, so you sometimes only need to purchase the single part and replace it to fix the problem.

the paper is crumpled in the lower part of the paper.


Maybe you have problems with the upper fuser roller, open the back door and try to see the upper fuser roller and lower pressure roller if you see any wrinkles or damage in any of the rollers that's is the problem, you can replace them just the upper fuser roller and the lower pressure roller but it will need advanced skills, the other option is change all fuser assembly but at higher price

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 and the fuser. Strange problem , when i let the paper out treu the back cover ,its oke. The gears seams to be oke. thanks Bas


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.

fuser gear xerox


1. remove front cover which is over the paper tray - 2 screws and then unflange and wiggle off.
2. take out toner cartridge and drum cartridge.
3. there is a screw on the top left of the plastic cover over the fuser roller - unscrew it and then wiggle off the plastic cover.
4. there is a little green screw on the right rear of the fuser roller assembly - unscrew it.
5. remove the 2 white plugged in wire things to the right of the fuser roller (right one snaps on top and left one snaps on the inside right).
6. take fuser roller assembly out of machine.
7. loosen screw on left on top of brown riser and loosen 2 screws on right that hold the wired part down - carefully remove the glass heat element, taking care not to touch it with your fingers. if it is touched with fingers, need to clean it with alcohol to prevent the grease from reflecting the light back into the element.
8. remove the lock ring on the right of the cyclinder and then the gear wheel will be removable and replaceable.
remember to take digital photos of it before you dis-assemble it so you will be sure you're putting it all back together right.
