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.

Display messge cru fuse error

Normally that means the fuser module has failed.
You can order and replace it yourself, I believe they are about $100.
That's what I paid for the last one I replaced.
You can call 1-800-835-6100 and order one.
All you have to do is remove the 4 screws that hold the back cover on, then remove 2 or 4 screws that hold the fuser in. Unplug a couple of plugs and slide in the new fuser. It is really an easy replacement.

Okidata c9500 paper jams between

If you are getting jams in the fuser or right after it the fuser is probly bad. I think there is a mylar upgrade that attaches to the toner sensor arms under the top cover(not an easy fix). It is also possible the drum unit or the toner cartridge could be bad.

Dell 5100cn is printing duplicate text and images..what do we do after vacuuming excess toner has not solved the problem?

Two possibilities.

You may need a new FUSER. The fuser is the hot thing in the back that bonds the toner to the paper. The fuser heat roller is coated with teflon so the toner won't stick to it while it's heating the paper. After a period of time/number of pages (usually 100,000+), the teflon wears out and the toner starts sticking to it and then gets transferred back to the paper after a revolution.

Is the whole image repeating? Chances are good that it's the fuser. If only one color is repeating, it's probably a faulty toner cartridge, as it may have worn out before the toner ran out. Have you changed cartridges yet? If you have not and don't want to buy another just to see if it will work, try a "half-page test. Start printing something. When yoou think the paper is about halfway through the printer, open the cartridge door to stop the printing. Don't worry about the error. Pull out the toner cartridge and see if the repeat defect occurs before the fuser. If it does, try a new cartridge. If it does not, you need a new fuser.

The Dell fuser is not as easy to change as an HP fuser, but if you are brave and have a screwdirver, you may be able to do it without calling a technician. Service manuals afor Dell printers are hard to track down. Fusers can be found online for about $200-300. Best bet, if you don't know what you're doing is to call a Dell authorized servicer.

HP Laserjet 3550 Fuser Jam Error 13.20 Had it in

You need to ask them to change the fuser..The fuser is the part of the printer that actually melts the toner onto the page. Here is a website that gives you more info on the fuser so they can't B.S. you anymore..either the fuser works or it doesn't..

Please rate this solution thanks.

Canon Error Eoo7

This error code indicates to the copier that the upper fixing film on the fuser assy is not rotating. Paper wrapped around the fixing film or the film itself is damaged may cause this. Unless you are very mechanically inclined , it will take the removal of the fixing assy and possibly the replacing of the fixing film assy. A tech would need to be called in to correct the problem. The fixing film is a replaceable item. Good luck.

Flashing lights

Hi, I work on these on a regular basis and have seen the problem many times. Almost every single time it's caused by a faulty fuser (fixing) unit. They are fairly easy to replace but they run in the 2-300$ range in cost. Good luck.

Fuser Error 50.1 Fuser is hot. What is a fuser?

I think the fuser is in your **** part. This problem can be corrected by sitting in a tub of salt water. Make sure the printer is plugged in and is powered on. Is the display lit? If it is place the printer in the tub of water you are sitting in. You sould now be able to realize nobody cares and it no longer matters
