Fuser drum ?

So we've wiped down each of the toner areas but we're not sure where the Fuser Drum is or what piece it is exactly. It's still printing the four little CMYK dots twice on each paper. This sounds like such an easy fix. What's the fuser drum exactly?

Re: fuser drum ?

The fuser is a rubber covered roller (located nearest the exit tray of the printer) that must get hot to work. as the paper is approaching the roller, the carbon toner is merely resting on the paper. when it reaches the roller, the heated roller presses and "fuses" the toner into the paper. now, i am not quite sure what is the real problem...does the fuser get hot? test it by turning on and waiting for the "OK" signal to begin print. then shut it off and quickly open the printer and touch the fuser (be careful!). if it gets hot, your problem is somewhere else, unless the rubber roller or the roller temperature sensor needs heavy cleaning, of course. the sensor is located under the roller cover and is touching the rubber and is identified by having two wires leading to it. sometimes this sensor is electrically ok, but carbon buildup acts as a thermal insulator and does not allow the sensor to feel the higher temperature. the printer will never reach the "OK" status if fuser not reaching the correct temperature, so you can quickly test if it is heating during the warmup period. let me know of any updates.

Poor print quality

Have a look at the fuser. This is seen by opening the rear hatch as if removing a paper jam. There is an Orange pressure roller and another roller which may be a brown or metallic colour. If the surface of the second is damaged or caked with toner, that is the source of your problem. The fuser can be cleaned if necessary, but is not really economic to replace. If the fuser is OK then there is a cleaning brush inside the Drum unit that needs to be cleaned and the drum cylinder should be cleaned with alcohol and cotton wool.

Black smudges down left side of page

How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

How to remove the cause of a black line a HP Laser Jet printer model 4250 has produced down the center of everything printed for a long time? Thorough cleaning has had a very little effect.Last week I...

In cases of print quality issues you should always start with the imaging drum. In this case the toner cartridge. Make sure it is not a re-manufactured or refurbished toner cartridge. A lot of times when someone refurbishes the cartridge they don't replace the imaging drum (the blueish green drum under the shutter). Check for toner stuck or burned on the drum. If there is you need to replace the toner cartridge

If there is no toner stuck or burned on the imaging drum then you more than likely you will need to check or replace the Fuser in the back of the machine. The back door of the machine comes out easily enough and the fuser clips into place. **Be careful it doing to be hot.** Remove the fuser and check the rollers inside for burned toner or damage. If so replace the fuser .

You can purchase a Fuser Kit from HP or find a refurbished fuser from Depot America or for a lot less.

Duplicate print below each line on copies/printing/fax, changed fuser unit and drum unit and had cleaned. Seems to happen after toner changes, can the toner cartridge holder be defective and cause this...

Try to stop the copier (by jamming a sensor or opening a cover) mid-way through the printing cycle. Remove the 1/2 copied document out from the drum area. Look to see if you have the double printing. This will eliminate the fuser as the problem. If you don't have the double printing then the fuser's cleaning roller may be shot causing repeat image. If it is in the drum area it will be hard to determine since you already replaced the drum(?). But there is a "cleaning" lamp or charge wire on the drum to check.

Oki 5150 color are not print right

You need to replace the magenta drum. Just because there is life left; it's possible it is scratched. Also, take a cotton ball dip in alcohol and wipe the LED's off when the cover is open; those black things that are hanging down from the cover. Also, make sure your drums are installed in the proper spots (magenta in magenta slot). If the toner "rubs off" after it prints... then the fuser is defective.

This post is loaded. First of all, there should be 4 screws holding in the fuser. Unless you are talking about removing the 2 screws that hold the pressure and heat roller together in the fuser. 4 screws hold the fuser in the machine, 2 screws hold the fuser together. I am not sure exactly if your fuser was mounted to the machine with only 2 screws, or if that is an accurate post and you removed the 2 screws that hold the fuser frame together. Either way, I seriously doubt the noise is coming from the fuser itself.
Now, the darker section down the middle. I would suggest taking the fuser back out of the machine and looking at the black heat roller in the fuser. If it is not clean and shiney, and has a rough texture to it in the middle, that roller is bad and will require replacing the fuser.
What I am curious about is, the rest of the copy. Is the copy fine outside of the middle? If so then the fuser should fix it. Note if there is some reprint, sort of ghost print in the middle of the page.
The rattle may be the gear on the back of the drum cartridge, It is a small gear that drives the cleaning roller. Pull out the drum and look on the back, there are 2 small gears on the back . One of them may have broken a tooth and is jumping and not rotating properly.
Another problem, as I read this may be the toner cartridge not having the ink distributed properly, To eliminate the toner cartridge as the problem. Remove the toner and look at the roller on the front of the cartridge.It shoud have ink distributed evenly across that roller, No streaking, it should be a dull black fuzzy apperance across the roller.
Firstr check the middle of the fuser roller for the wear I described. Then the back of the drum for the noise, then the toner carteidge for distribution.
If its not fixed yet, let me know. We can discuss the laser and scanner issues. But those are far less likely.
You posted a good one...

Smudge marks on paper; otherwise normal

fuser is usually replaced as a assembly, it's the hot bit a back.

Can only be two things the drum or the fuser as our headstrong friend has correctly explained.

More than likely it is the drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine

Printing CMYK dots twice on every print

Hi, As it's printing two little strips (like a 1/4inch) of CMYK dots (one of each color all you need to check the toner cartridge drum, try to wipe the toner drum with a damp cloth on each color cartridge. Secondly check the fuser assembly drum if it has any mark on the drum, try to use a mild isopropyle alchohol to wipe the dirt mark them try printing. this will resolve the issue. if still issue persists then change the color cartridge one by one. This will definitely resolve the issue.

Improve print quality

If you have changed drum AND toner, and reset drum count, cleaned scan slit glass on lit then only other thing to clean that can cause dirty prints is laser glass, (remove drum, inside where drum goes there is a slit the rund width of printer on inside middle "ceiling"

The orange piece I take it is the lower heat roller at rear, cleaning this is not going to fix anything.. this area called the fuser sometimes the fuser wears the coating off the upper heat roller (above orange one) and leaves like a smudge mark on prints, like I say cleaning wont fix replacingfuser with new would be what is required

I find a lot of grey shading on prints on this model are from faulty toner cartridges, next is drum then worn fuser roller... Stop a print half way (timing) in machine remove drum and look at print, after drum but pre fuser ,to see if image is ok before entering fuser, then we know if that is your problem
