Hi,
This could be a couple of things, easiest thing to try first is to put a different toner cartridge in, something that has already been opened because it would save you from opening a new one. Another thing you can try is sending a cleaning page through the printer to clean off excess toner from the fuser unit. What happens is over time toner builds up on the lower pressure roller of the fuser unit and after being heated and cooled so much the toner starts to flake off on your print outs. Follow these steps to try to clean the lower pressure roller:

To run the cleaning page manually
1.If a duplexer is installed, open the rear output bin.

2.Press check mark(SELECT button) or the MENU button to open the menus.

3.Use (UP ARROW button) or (DOWN ARROW button) to scroll to CONFIGURE DEVICE, and then press

4.Use or to scroll to PRINT QUALITY, and then press the check button

5.Use (UP ARROW button) or (DOWN ARROW button) to scroll to CREATE CLEANING PAGE for the(LJ 4200/4300) or PROCESS CLEANING PAGE if you printer is a(LJ 4250/4350) then press the check mark

6.Follow the instructions on the cleaning page to complete the cleaning process (LJ 4200/4300
only).

7.If a duplexer is installed, close the rear output bin.

This should help clear some of the flaking toner, if not you might have to replace the fuser unit.

I would try a new toner cartridge. The fuser might not be heating correctly.

Use this item to configures the fuser mode associated
with each media type.
Change the fuser mode only if you are experiencing
problems printing on certain types of media. After you
select a type of paper, you can select a fuser mode
that is available for that type. The available selections
might include some or all of the following modes:
NORMAL: Used for most types of paper.
HIGH 1: Used for rough paper.
LOW: Used for transparencies.
HIGH 2: Used for paper that has a special or rough
finish.
The default fuser mode is NORMAL for all print media
types except transparencies (LOW), and rough paper
(HIGH 1).
CAUTION
Do not change the fuser mode for transparencies.
Failure to use the LOW setting while printing
transparencies can result in permanent damage to
the printer and fuser. Always select Transparencies
as the Type in the printer driver and set the tray type
at the printer control panel to TRANSPARENCY.
When selected, RESTORE MODES resets the fuser mode
for each media type back to its default setting.
Hope this helps

SOURCE: Black toner flakes off photo paper

Are you sure that you should be using PHOTO paper in a LASER printer? They usually only use ordinary unglazed paper.

SOURCE: The toner flakes off of labels and report card

It sounds like the fuser isn't working properly. If the printer does this with all kinds of paper then you may just have to replace it. However, if it only happens with certain print media then you probably just need to change the printer settings to fit that type of paper. When you select "Print" in any program a window should pop up with the printer options. Look for a button that says "Properties" or "Preferences." In the printer properties/preferences there should be a menu where you can select the paper type and size. Adjust it to what you are using and see if that helps; different types of paper require different treatment. If the paper is glossy, look for a setting for that as well. You can try to access the preferences directly from the printer as well, some printers will let you select paper type, while others only from the computer.

I hope this helps! Good luck!

Set it or computer, whatever you are using to cardstock, or it may be called thick,there are multiple selections depending on the media. Beacuase thick paper requires slower speed and hotter fuseing.

It seems like the toner isn't sticking to the paper, or its too thick and flakes off. Is this a saturation problem, paper stock, or maybe a drum or toner issue? If I rub my fingers over the copy it...


The first question is what kind of paper are you using???? Are you using regular copy paper? Have you gotting any error codes? If you are running plain copy paper in the copier and the toner is flaking off, odds are you are having a problem with the fuser unit. Look to see if the toner is fixed on one side of the the paper and not the other side. Odds are you have a problem with the pressure of the two fuser rollers. You may have a cut in the lower fixing roller or a broken ball bearing... Good Luck

could be the fuser but there is a setting for heavy paper or card stock which will slow it down and increase the heat. depends on your model as to where this can be changed.

My printer is flaking. i am printing a heavy color image on a kyocera fs c8026n. any help?


If by "flaking" you mean that the print is rubbing or flaking off then there are 2 possibilities. If you are using thicker than standard 20lb bond paper then when setting up the print job make sure you are selecting thick paper on your paper setting. This is a common problem if your paper is thicker, shiny or anything other than standard.
The other possibility would be a fuser defect of some type. But that would tend to affect standard black and white prints as well.
Try the thick paper setting as it will slow down the paper speed thru the fuser and will "fix" the toner to the paper better.

Is the toner fused to the paper, or 'loose', and can be rubbed of easily. Are there 'flakes' of toner, that may or may not be loose?

If the toner is fused, the cartridges are likely to be leaking toner - especially if they are remanufactured - not easy to get right, and even more difficult to get right if 'home refilled'.
Solution to this is replace cartridges, or if these are new return them to supplier as faulty.


If there are 'flakes', it is likely to be the fuser that is contaminated with toner that has ot fused to previous pages - usually as a result of using the wrong type of media, or setting the wrong paper type when printing on thick media.

Fuser can be cleaned, or in extreme cases replaced.

Specific PDF Document/Specific Print Area Black Toner Not Fusing And Flakes Off


Without a doubt you have a problem with the fuser.
What that is caused from is buildup over time of ink on the heat roller. The teflon coating wears some and the ink sticks to the aluminum instead of pealing off onto the paper.
You then do not get enough heat or perssure to "fuse" the image into the paper.
Replacine the fuser will correct the problem.
