Fuser's don't have a 'reset'.....they just get hot and melt the Toner onto the paper.

I think you mean "how to reset the maintenamce counter".

Go to this page and watch this video for replacing the Fuser Kit on your model printer.

Lexmark T650 T652 T654 Fuser Maintenance Kit Replacement and How to...

To reset the maintenance page counter to zero:

To reset the maintenance page count to zero:

1. Touch "Right Arrow" to select Reset Maintenance Counter from the Configuration Menu.
2. Touch Yes to reset the counter, or touch No to exit without resetting the counter.

There is a maintenance kit you need to get and install. Then you'll have to go into maintenance mode and reset the maintenance count. I don't remember the button sequence, but if there is a printere repair shop in your city, most likely one of their techs will tell you how to reset the count. But you really should install the kit first. It consists of feed rollers, charge and transfer rollers, and fuser. It's not difficult to install and the kit can be purchased with a refurbished fuser from many vendors at reasonable prices.

Hello. Welcome to Fixya
Actually Error 80 is "Scheduled Maintenance Message"
You can reset the maintenance count by going to the Configuration Menu
Follow the given steps to solve it:

• First of all Turn off your printer
• Hold the 2 and 6 buttons while the printer is off
• Turn on the printer but don't release the buttons yet. Keep holding those buttons for about 10 seconds
• On your Operator Panel, you should see "Configuration Menu"
• Scroll down and look for "Reset Main Count" and select it.
• Exit Configuration Menu and turn the printer off then back on

I hope it will be solved, If it doesn't work then You are required to purchase the maintenance kit and have it replaced even if the printer is still under warranty. Some maintenance kits can be installed without the assistance of a technician. However, some warranties cover on-site installation of the maintenance kit by a technician after you have purchased the kit.
In this case you must be contact to LEXMARK service provider, To get support by LEXMARK on phone, then call at 1-800-539-6275

This issue is just like changing your oil or the timing belt on your car. If you don't fix it correctly it leads to other problems. So, be warned. :+)

Here's what the Lexmark KB says:

On the Lexmark T520/522 series printers, we recommend that the maintenance kit be replaced after every 250,000 pages. If possible, an authorized service technician should replace the maintenance kit parts on these printers.

On the Lexmark T620/622 series printers, we recommend that the maintenance kit be replaced after every 300,000 pages. The maintenance kit parts for these printers are customer-installable, but some dismantling of the rear area of the printer is involved.

Note: The maintenance kit may need to be replaced more often if the customer is running heavy media (like card stock or labels) through the printer.
It is possible to clear the maintenance error message without replacing the kit. The printer will still operate, but some print quality problems may arise. However, this is not recommended as the message serves as a reminder that maintenance is due. If the printer is under warranty, the customer has to purchase the maintenance kit and have it replaced in order to keep the warranty active, although the on-site replacement itself may be covered under the warranty.
The parts that make up the maintenance kits are:
A fuser unit
A transfer roller
A charge roller
To find the part number of the maintenance kit needed for your printer, see Printers / Maintenance kits.
Clearing the maintenance message
To clear the message, you will need to go into the printer's configuration mode. Do the following:

1. Press and hold the SELECT and the RETURN buttons as you power the printer on.
2. Hold the buttons for six to eight seconds after turning on the power, then release them. (If you receive the maintenance message, press the Go or the Select button to continue past it.)
3. Now, press the right Menu arrow until you see RESET MAINT CNT.
4. Select this. You may need to press the Select button again. The printer display should briefly flash SAVED.
5. Power the printer off and then back on in the normal way. The printer should now power up normally.
6. If it does not and the error returns, repeat the above procedure.

There is a great video that shows step by step how to install the fuser, transfer roller, charge roller, pick up tires and then reset the 80 Scheduled maintenance message
