The 921 service fuser error indicates the fuser indicates that the fuser unit failed to reach the standby temperature. This usually requires service. But here's a couple of things worth checking:

• Unplug printer from power source, replug after 30 seconds. Make sure to plug the printer straight to the power outlet in the wall. Bypass any surge devices or power strips as they can cause low amperage resulting to false fuser error.
• Check Maintenance kit count. Go to Configuration Menu by pressing Select and Return while powering on the printer. If count value reached 300,000, maintenance kit should be replaced.

If error continues, don't hesitate to contact Lexmark technical support or your authorized service provider for assistance.

this sounds just like a worn out fuser. pull the fuser out and inspect the rolllers if the orange roller (the pressure roller) has bad wrinkling or if the shinny sleave of the roller has slid off to one side replace hte fuser

this is either caused by a simm card being corrupted or the engine board being bad. remove the simm card to isolate the problem

this is a software communications error and can be caused by any of the pcb's installed in the printer. start with the simms and remove the boards one at a time untill you isolate which board has caused the problem. this can be as easy to fix as cleanig dirty contacts where the board install in the inter connect board. to having to replace the board

shadowing or ghost printing is usually caused by a fuser that is not running at its opperating temperature the fuser is the problem about 85% of the time. the thermistor is directly responsible replacing this part will clear up the prolem or repace the whole fuser depending on the wear. toner cartridges can also do this for the toner to do this its usually a expose drum has been set down on a dirty or rough surface thus compromising its surface

Hi there
All this is down to is taking all the rollers off and gave them a good clean in worm water or try clean then in there place and make shure they all free running.
All the best Pineworks

Try putting the old fuser back and see if it gets rid of the error, then if that's the case the new fuser is defective. If not, here's a link to the Lexmark website which gives you instructions on what to do when having that "Invalid Engine Code" error message. http://bit.ly/9D61W3. Hope this helps. Let me know if you need more assistance.

Most times is it dirty rollers that pick up paper. You can get cleaning kit for it and most times just remove the paper tray and clean all of the rollers and also open all of other doors and if there is a roller clean it too. Make sure you use cleaning kit or it will get even worse. Also make sure you unplug it and if it has fuser that is has cooled down. Hope this helps.

Did you change the chargeroller?? This is the roller that comes down on the cartridge when closing the frontcover. Some times cleaning the chargeroller with a dry cloth will help. You can take it out by closing the frontcover half and then push the chargeroller carfully to the right so it comes out of the bearing on the left.

this is an error that will return you can reset it sometimed hold the right arrow select and go buttons down and power the unit on. when you see action in the display release the buttons. if the nvram has any uncorrupted space left on it the nvram will be relocated to that spot. this is only a band aid and the engiine board needs to be replaced

Don't know if you solved this alread, but take a look at the 'exit flag' located just where the paper is spit out of the printer. If the exit flag is in the "up" position, just bring it down and that should solve the problem. If the exit flag is in the up position, this makes the printer think that the bin is full. Hope this helps. Either that or http://support.lexmark.com

Service manual indicates this is a logic board issue, but I've seen this error numerous times, and a logic board never fixes it.

What ends up being the issue is a bad print job, could be caused by a bad driver. Test by disconnecting the printer from network, and printing the menu settings from the panel. If it prints, then it's a bad print job or driver.
