      Turn off the printer and unplug the power cord from the wall outlet. Wait at least one hour for the fuser assembly and other internal components to cool.

    • 2
      Open the back cover of the printer. Squeeze the two tabs located in the upper left corner of the back cover, then pull the cover off the printer body.

    • 3
      Push the two green tabs on the duplexer unit and pull the unit out of the printer. If your printer is not equipped with a duplexer, skip this step.

    • 4
      Remove the two screws on each end of the fuser. The screws are large enough to remove by hand. Grasp the orange tabs on the fuser and pull it straight out of the printer. Line up the new fuser and slide it into place on the track where you removed the old one.

    • 5
      Replace the screws on each end of the fuser. Turn the screws by hand until they are tight. Slide the duplexer unit back into place, pushing it into the slot until it locks in place.

Poor print quality

There are three main reasons why you get defective printouts - toner cartridge, drum unit or the fuser assembly. Clean them with non corrosive solution or replace when necessary. That should set the printing back to normal.

I have an error code E001 on my canon copier what could be the problem

This error usually is due to fuser unit temp failure. check that there is no dirt under thermistors and that there is contact with fuser rollers. distortion of round fuser rollers can also cause the thermistors to temporary loose contact with rollers, causing falsely low temp readings sent to main-controller which in turn will give out a error. If you decide to strip and check fuser,it can be extremely difficult so take pictures of everything you do so as when it comes to assembly you wont get things wrong. check thermistors for damage, dirt or poor contact with fuser rollers. also check that the fixing bearings are not worn or damaged as this will cause rollers to move away from thermistors. Good luck.

I need to remove the fuser assembly on a Konica Minolta C550.

First turn power off, there are 2 switches. One on the side of the lcd screen and the other is located on the lower right front side. Then unplug from the wall outlet!!!
Now open the r side vertical transport door( note if the fuser unit is hot wait aprox. 30 minutes too cool down) remove the 2 silver screws which are directly on the fuser unit ( use a magnetic tip screw driver, this will make it easier) gripit with both hands to avoid letting the fusing unit fall down.When reinstalling the fusing unit,
be sure to press the fusing unit into
the machine until the surfaces of the gear mesh are seated ok.( there is a green knob to the right that you can turn whch will allow the gears to rotate.
next step is to reinstall the silver screws, and close the transport door. Now you can plug the power cord back in to the wall. and turn on the power switches. Note the fuser counter will automatically reset itself to 0 ( that is if you installed a new Fuser unit.) There might be a funny smell for a couple of hours due to the new unit installed fuser. Good Luck

Machine error 76 for brother fax 4750

The error is related to the fuser assembly overheating. The only course of action you could take would be to turn off the machine for an hour or so to give the memory time to reset. If that does not resolve the problem, then the fuser assembly needs replacement (Part# LJ7759001). This should be replace by a certified tech.

Hope this helps!

Samsung sf-5100 fuser error

I am not familiar with this model but the fuser assembly is typically located very close to the exit area of your unit.
This MAY be either a quartz lamp or a solid state heater that uses heat and pressure to fix the loose carbon permanently to the paper.
Its operation can be noticed (if working) by a pronounced higher level of warmth near the document exit.

This may be user replaceable but I wouldn't advise it unless the operator's manual describes the procedure.

The part is not terribly expensive:

Scan down the page for your model number.

Before siccing a tech o nthis, you might want to open the machine as far as you can without unscrewing stuff and inspect the guts of it; sometimes the error code is wrong about the source of the problem but in this case, it is technically simple to monitor the fuser temperature and report the failure to heat.

Gear making a grinding noise

Not too good news I'm afraid. It sound like the fuser gear has failed. Generally the fuser unit (hot section or hot rollers in the back) need to be replaced. Usually when the gear has worn or failed the fuser rollers are also worn and need to be replaced. The gear can be replaced seperately but is a very risky operation and usually results in parts in the fuser unit falling appart due to age and wear, so it is best done as a unit. If possible do not run the machine as it can cause damage to gears around the fuser unit. The best option is to find out how much a fuser unit and labour to fit would be at your local service centre.

Fuser thermistor fuser unit or lpc board

the fuser thermistor makes contact with the heat roller. Normally they are in the middle of the roll.
If you are experiencing a fuser error. Most likely the upper fuser will need to be replaced.
Boards on faxes are mounted on the sides and base part of the frame
