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.

How to replace toner cartidge of the Xerox Copier 5225 machine?


The toner cartridge is located in the upper centre of the front of the copier. Open the front door, slide out the cartridge until you see the top handle, whilst pulling out hold the top handle to avoid the cartridge tilting and leaking any excess toner inside the machine.
Before inserting your new cartridge, gently shake it from side to side to ensure even distribution of the toner. Slide the new cartridge in until you here a click, then close the front door. Your copier may go into a calibration routine for a minute or so if the developer has been starved of toner. If it hasn't, it will be ready to copy straight away.
For a quick user guide on the copier go to http://download.support.xerox.com/pub/docs/WC5225_WC5230/userdocs/any-os/en/EN_Online5230_5225_5222_QUG.pdf
Hope this helps.

hello, sounds like there are many possible solutions for you machine, first with paper jamming, are labels going thru manual feed tray, or paper tray, it might be possible that mp feed roller needs cleaning or replacing. if paper tray, simple would be feed roller, clean or replace, if jams continue with normal paper from paper tray, the problem will be front door, i have yet to be able to repair paper jams when front door assembly fails. as far as colors, both drum and toner can cause this problem, if using 3rd party toner, this will also cause some color problems. sorry no real quick fix for this machine, i've tried.

I cant fix the paper jam problem. every time i take the paper jam out it jams again


I have had paper jams in five different places on this machine. It has jammed at the pickup point from the tray, in which case you have to remove the paper tray and pull the jammed paper out. It has jammed at the manual paper feed tray, in which case you just have to pull the jammed paper out of the feed rollers. It has jammed at the toner/drum, in which case you have to open the front cover and pull the toner cartridge out to remove the jam. It has jammed in the back of the machine where the paper feeds through to the output tray, in which case you have to open the small back panel and remove the paper. And it has jammed in the output rollers, in which case you have to reach inside the output tray and remove the paper. Then once the jam is cleared there are times when the machine has to be unplugged for up to 8 hours to reset before it will function properly.

Toner not set insert toner message


The problem is with the paper tray not the toner, believe it or not. Take all of the paper out of the tray and then reinsert the paper into the tray. It should then work fine.
