Question about Lexmark C720 Laser Printer
We just replaced our yellow toner cart, and now during warm up and printing, we get a buzzing sound that seems to be coming from under the top cover. I inspected all of the gears that are visible to me for binding and they all pass. I removed and reseated toner carts, photo developer cart, and fuser unit. During recycle after top lid is closed, there are two short buzzes, followed by two longer and faster buzzes.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

To reset the 'MT CARTRIDGE FULL SOON' error.
Enter Service mode Hold down the paper source and online button at the same time, hit the power button once.Continue to hold down the paper and online buttons until you see the printer name "Canon W6200" on the printers LCD display, then release the two buttons.The printer will initialize & enter service mode.
In service mode, scroll sideways until you see the 'Initialize' menu, scroll down to 'W-ink', and press enter. At this point I did something (scroll sideways and hit enter I think) and it came up with 'New W-ink Cart' Hit Enter to get '=New W-ink Cart' and Online to Accept. I powered down and back up, error all clear.

From the site of your Picture, you need a new fuser unit.
The coasting is peeling off... that is not good. And I will bet you get allot of paper jams.
To replace the fusing unit is not hard to do. For the most part taking the covers off the machine and getting them back on is the hard part... Let the fuser unit cool down before you touch it..
Just remember to unplug the machine, Electronic Static Discharge is not good for the Boards in it, touch the metal chassis before you touch the boards if you don’t have a wrist strap) get your self a table and some room to work and take your time.
Take the toner cartridges out
I would do a maintenance kit while I had it apart. (rollers, transfer rollers etc)
Vacuum it out; clean it while you have it open.
(Warning toner and developer is very fine, you might need a vacuum with a micro filter on it, other wise it might go every where)
The service Manual has details on how to do all this. If you follow that you should be ok.
You could try to get all the parts to Fix the fuser unit, but it is easier and faster, cheaper to replace the whole thing. Some places offer a core exchange.
If you need any assistance let me know...
This is from Lexmark
These are various other places that offer parts and supplies.

Xerox does not list that model at all - are you sure the model number is correct ?
It would appear that either the cartridge or fuser may be defective.
Does the machine show any error codes at all ?
Here is a user manual for a similar model 3225 that may help under the troubleshooting section :
This is where you find manuals for all Xerox products :

SOURCE: my dell 3110cn printer is
This error message indicates that the printer has failed to read information from the chip on the black printer cartridge.
This is either.
1. Black cartridge not fully pushed into place (I've been called out to a couple like this)
2. Faulty chip on the black cartridge - effectively not responding to the printer 'talking' to it.
3. Fault on the main board of the printer.
1. Push the cartridge fully home.
2,3. If you have an old black cartridge, try that. The message should change to Replace Toner, if it does, its the chip on the cartridge, if it doesn't its the printer.
