Did you replace the fuser with a new Lexmark fuser or a refurbished unit? The original Lexmark units have a chip in them that resets the counter when installed. However this only works the first time the fuser is installed. If you install a used fuser in a different printer it will not reset the counter.

Was the replacement fuser 'new' or 'refurbished'? Try re-installing the fuser, that will usually correct the problem. If not, contact your vendor & see if they will exchange it. Always try to replace parts with Factory New. I don't work for or represent any brand, but in always tell my customers: Buy new Factory parts.

1. Switch off the machine, then switch on the machine.
2. Enter dC330 code 10-100 to heat the fuser to 180 degrees. Enter codes 10-200 (centre
thermistor) and 10-210 (front thermistor) to verify the condition of the thermistors.
3. Enter code 10-300 to check power supply unit 2. If necessary, install a new power supply

Item 8.
NOTE: A cold fuser has a resistance of approximately 11.5 ohms (220V/240V) or 2 ohms
(110V).
6. Check that there is continuity through the fuser heater and across the over temperature
cut-out.
7. Check the wiring between the fuser connector, PL 4.15 Item 20 and CON3, CON8 and
CON9 on Power Supply Unit 2. If necessary, install a new fuser connector, PL 4.15 Item
20.
8. Check the wiring between CON4 on Power Supply Unit 2 and CN7 on the Main PWB.

Hello,
To resolve the issue, please try reseating the fixing assembly. To do so, please follow the instructions below:
1) Unplug the power cord from the wall outlet.
Caution: The fuser unit and surrounding area can become extremely hot during operation. Perform the following procedure after the fuser unit has cooled down completely. Touching the fuser unit when it is still hot may result in burns.

2) Turn the lock release levers located on the back of the machine in the direction of the arrow and release the lock.

3) Hold the grip on the fuser unit and remove it.

Caution: The fuser unit weighs approximately 3.3 lb (1.5 kg), and it is heavier on the back side. Be sure to hold the grip securely when carrying a fuser unit. Dropping the unit may result in personal injuries.

4) Hold the grip on the fuser unit and install it securely.

5) Lock the fuser unit by turning the two lock release levers in the direction of the arrow.

6) Connect the power cord and all interface cables.
7) Plug the power cord in the wall outlet to turn on the machine.

Hi belljohnson5,

The code is caused by a small switch under the fuser unit not sensing the fuser unit is in place. The blue plastic locking tab on the left side of the fuser has a small catch on the bottom of the fuser. The catch is supposed to slip thru a space in the steel plate under the fuser unit and secure the fuser in place. As the catch slides forward under the steel plate, it pushes on the trigger of the sensing switch, closing the sensing switch and letting the copier know that the fuser is in place. (there is also a similar locking tab on the right of the fuser but it doesn't trigger a sensor like the left one does) 1) The fuser gets very Hot!! Let cool for 10 minutes after turning off the power and unplugging the copier! 2) Pull the two blue locking tabs forward and remove the fuser unit. Reinsert and push back on the tabs to lock back into place. Sometimes just reinserting the fuser will allow the catch on the locking tab to function correctly and push the trigger on the sensing unit. Turn the copier back on and pray the error code doesn't reappear.. 3) Mine reappeared. Evidently the catch on the fuser unit was still not pushing the trigger forward, causing the copier to surmise that no fuser unit was installed. At this point, you should buy another fuser unit or take your copier to an authorized Dell repair center.

Hope this helps.

Thank you for using FixYa.

The fuser unit for this machine can only be installed by a technician as the fuser unit itself is not for sale to consumers.

If you want to clear the fuser message you have to be sure you replaced the fuser web. Then go to 25 => counter clear(items 13)=> Clear fuser counter or 36=>counter clear(items 8)=>Clear fuser counter.
