Toner not refreshing

Bought a new toner cartridge, replaced it, at first it said no cartridge, solved that one, then printed and the top of the page is dark, but slowly fades as it gets lower on teh page. After sevel sheets printing, it gets litghter and lighter. Pulled cartridge out, turned drum, tested all gears on cartridge and adapter, all work, but when printed another page, it was great at the top, but faded at the bottom. Pulled cartridge again and realized that the toner bar is not runing, so it is tring to print all pages on the same spot on toner cartridge. Bringing another adapter/cartridge assembly to test to see if it is the adapter or printer.

    I have the exact same problem! The bar is not turning. As I look in the Drum, I see that the drum is not connecting with the toner cartridge. How can I fix this?

Changed toner---back side now prints dirty with band on the top. Did the cleaning procedure - no luck


If you changed toner because old was empty and now you have this defect with the new cartrige, it is most likley a defective cartridge. Try the old cartridge again, if it prints clean, then you know for sure it is the cartridge. If you purchased a new HP cartridge, get it replaced by HP, they warranty their toners against defects. If you bought a 3rd party toner, return it to where you bought it and get them to replace it. If you had your old toner refilled by someone, get your money back, they don't know what they are doing. This type of defect is often caused by a filled waste toner bin then then runs back out when you print. Some refillers just throw toner in and don't empty the waste toner bin.

Run the 1/2 print test.
Print a few pages that have failed previously and as the printer is printing open the cartridge cover(top cover).
Pull out the cartridge and look at the paper down below. If the page looks good, you probably need a new fuser. If the page is messed up you could have a bad transfer roller or another bad toner cartridge.

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.

Dell 1720 lazer printer only printing solid black pages


The corona wire is not charging the drum properly. Try pulling the toner cartridge out and then re-seating it. If this doesn't work, try a new toner cartridge as the corona wire is usually included in the cartridge.

If you are using a refill toner, there's an outside chance that the supplier put toner with the wrong electric charge in the cartridge. Again, changing the cartridge should fix this(assuming the replacement is from another batch).

Laserwriter 8500 prints splotches all over the page.


Toner bubbles are characterized by large blotches of color toner on
printed pages caused by color toner leaking from cartridges directly
onto the transfer drum.

Solve the problem of toner bubbles by checking the manufacturing
codes on the toner cartridges and replacing cartridges as needed. Compatible carts are notoroius for this so don't use them.

Heat-stamped on the toner cartridge, opposite the label-end of the
cartridge, is a manufacturing code. If a portion of the code does not
match the list below, replace the toner cartridge.

Use toner cartridges that contain any of the following manufacturing
codes:
 9I
 9J
 9K
 9L
 and any cartridge that begins with the numbers 0 through 6 in place of
the 9
