    I have the same problem - if you figure out what is wrong let me know please. Also, when my pages print it looks like there is light gray toner over the whole page... very faint, but noticeable. Any ideas on that one as well?

I have had a similar problem. . Black drum needed changing. There was also a grinding noise developing. I have taken each drum and toner module out of the printer and booted it up with one of the 4 missing. It was the Cyan drum that was making the noise. . Question is what can I do? I am not a printer expert. .

I will contact the local printing shop that I use for more info and will come back to you. I suspect that I will need a new drum . . .

Just wondering: my printer's yellow and black toner are both empty and need replacing. Would this cause the printer to calibrate for minutes at a time? After calibrating, I tried printing a document with...


If your going to print in color may it be just red or blue. You really need all of the cartridges for it to work. Because for the printer to come up with those colors. It would need all three colors Cyan, Magenta and Yellow to come up with the any color, in your problem, Blue and Red.

The toner tray will not pull out from the machine


Replacing the Toner Cartridge
The MFC can print up to 6,000 pages using a high yield toner cartridge. When
the toner cartridge is running low, the LCD shows TONER LOW. The MFC is
supplied with a standard toner cartridge that must be replaced after
approximately 3,000 pages. Actual page count will vary depending on your
average document type (i.e., standard letter, detailed graphics).
Discard the used toner cartridge according to local regulations. If you are not
sure of them, your local Sanitation Department. Be sure to seal the toner
cartridge tightly so toner powder does not spill out of the cartridge. When
discarding used toner cartridges, keep them separate from domestic garbage.
We recommend that you clean the MFC when you replace the toner cartridge.
1 Open the front cover and pull out the drum unit.
Place the drum unit on a drop cloth or large piece of disposable paper to avoid
spilling and scattering the toner.
2 Hold down the lock lever on the right and pull the toner cartridge out of the drum
unit assembly.
Caution
Handle the toner cartridge carefully. If toner scatters on your hands or clothes,
immediately wipe it off or wash it with cold water.
3 Unpack the new toner cartridge. Place the used toner cartridge into the
aluminum bag and discard it according to local regulations.
 Wait to unpack the toner cartridge until immediately before you install it in the
MFC. If a toner cartridge is left unpacked for a long period of time, the toner life
is shortened.
 You can use only a genuine Brother toner cartridge (TN-430 or TN-460), which
is specially formulated to ensure top print quality. Using another brand of toner
cartridge may void your MFC’s warranty. Warranty coverage does not apply to
problems caused by the use of 3rd party Toner, 3rd party Toner Cartridge or 3rd
party Drum unit.
4 Gently rock the toner cartidge from side
to side five or six times to distribute the
toner evenly inside the cartridge.
5 Remove the protective cover.
6 Insert the new toner cartridge in the
drum unit until it clicks into place.
7 Clean the primary corona
wire inside the drum unit by
gently sliding the blue tab
from right to left several
times. Return the blue tab to
the Home position ( )
before reinstalling the drum
unit assembly.
Reinstall the drum unit and close the
front cover.
Replacing the Drum Unit
The MFC uses a drum unit to create print images on paper. If the LCD shows
CHANGE DRUM SOON, the drum unit is near the end of its life and it is time
to purchase a new one.
Even if the LCD shows CHANGE DRUM SOON, you may be able to continue
printing without having to replace the drum unit for a while. However, if there
is a noticeable deterioration in the output print quality (even before CHANGE
DRUM SOON appears), then the drum unit should be replaced. You should
clean the MFC when you replace the drum unit. (See page 21-18.)
Caution
When removing the drum unit, handle it carefully because it contains toner. If
toner scatters and your hands or clothes get dirty, immediately wipe or wash
with cold water.
WARNING
Just after you have used the MFC, some
internal parts of the MFC are extremely
HOT! So please be careful.
The drum unit is a consumable item, and it is necessary to replace it periodically.
There are many factors that determine the actual drum life, such as temperature,
humidity, type of paper and how much toner you use for the number of pages per print
job. The estimated drum life is up to 20,000 pages. The actual number of pages your
drum will print may be significantly less than these estimates. Because we have no
control over the many factors that determine the actual drum life, we cannot
guarantee a minimum number of pages that will be printed by your drum.

Pages full of toner / toner streaking


First off, this is a comment from a random person who may or may not know ALOT about these printers and toner/printer design in general. All toners are not designed to the same specification. Toner is a combination of plastic "pigment" and iron like shavings to make it magentically attracted to the electrical charges within the unit. Different toners conform to different grades and mainly size of the particles within the blend. The manufacturer doesnt only recommend that you use their toner to make them money, yes of course it makes money, but its because when the unit is designed it is designed to use a certain grade of toner, trust me if you put the non-branded toner vs the branded toner under a microscope you would see quite a difference. Often the non-branded toner is much larger in particle size (obviousely because its cheaper to make at this spec). This causes a variety of issues from excess toner not being cleaned off of developer rollers, IDT rollers, or clogging of toner dispenser tubes in the unit and the micro filters contained at the toner dispenser assy and developer assys. Also as for the issue not changing when switching to dell branded toner - the dispenser tubes within this unit contain up to 500-1000 pages worth of toner, making no change in toner you make immediately visible. Also depending on the damage caused by the previous toner, it may not be able to be fixed until all the components in between the toner and final delivery (drum cart) are replaced. In this case more than likely the toner dispenser assy, all developer assy's, and drum cartridge need to be replaced, and than be sure to stick with factory branded toner :)

There is a cheap under the toner... it is probably corrupted... with a screw driver you should take it out and replace it with the old cartdrige toner.

Konica minolta error


I had the same problem and found that one of the toner cartridges must have not been seated properly. I removed the black toner cartridge and re-fitted it. The printer now works fine again with no errors. 17H is a code relating to a fault in the rotation ......... possibly one or more toner cartridges need checking. Use the menu on the printer to turn it to the appropriate position (i.e. engine menu then select replacement of whichever toner you are checking).
Hope this fixes your as well.
