Here's some info:

921 Fuser Error and 922 Fuser Error messages indicate that the fuser unit failed to reach the standby temperature.

  • If this is the first time you have seen the error, turn the printer off and on. Leave the printer off for at least 10 seconds before turning it back on. This gives the printer's engine board a chance to reset.
  • If this is an intermittent error, you may want to check how the printer is plugged in, even if it has worked on this surge device for months. Make sure the printer is plugged straight to the wall and not through a surge device or power strip. Power strips and uninterrupted power supplies can cause a low amperage problem in your printer which can trigger a false fuser error.
  • If this does not help or if this error appears every time the printer is powered on, you will probably need service on the machine.

What is the fix for a 921 service fuser error?


Service Fuser Error appears when the fuser does not warm to the required temperature. For this error on this Lexmark model, the manual states you should power off the printer and power it back on, and if it is not plugged into a wall power point, change it to a power point mounted directly on the wall. Personally, I never got a Lexmark printer to work doing this, but this is in the manual. If this won't help, and the printer is under warranty, you should log it in with the servicing company.

If the printer is out of warranty, your next option is to change the fuser which costs around $300, so I think you would be better off getting a new printer unless you find a second hand one on Ebay.

I have an error on my Lexmark T632 printer saying 933 service printhead error, can you tell me what this means


Printhead error message indicates that the printhead (laser scanner) unit inside the printer is not working correctly.
First step trying to fix this is to turn printer off, and back on after 10 seconds. If this won't clear it, try and plug the printer in a different power point straight into the wall. If the error does not clear, the printer will probably require service to correct the issue.

921 service fuser error


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.

921 service Fuser error


921 Fuser Error indicates that the fuser unit failed to reach the standby temperature. Leave the printer off for at least 10-15 seconds before turning it back on. This gives the printer's engine board a chance to reset. Make sure printer is plugged in straight to the wall, bypass any surge device or power strips as this can cause a low amperage problem in your printer which can trigger a false fuser error. If this does not help, you'll probably need service on the machine since it deals with the LVPS, the fuser and the system board.

We have an Optra M412 that has a 921 Service fuser error. We don't know where to find the fuser


Service Fuser Error appears when the fuser does not warm to the required temperature. For this error on this Lexmark model, the manual states you should power off the printer and power it back on, and if it is not plugged into a wall power point, change it to a power point mounted directly on the wall. Personally, I never got a Lexmark printer to work doing this, but this is in the manual. If this won't help, and the printer is under warranty, you should log it in with the servicing company.

You can find the fuser at the back of the printer, remove the cover and there it is. It holds in two screws and a power connection. If the printer is out of warranty, your next option is to change the fuser which costs around $200, so I think you would be better off getting a new printer unless you find a second hand one on Ebay.

Error 921 fuser


This indicates that the fuser isn't heating up enough and is too cold. Either the thermistor, bulb, or power supply is on the fritz. I would replace the fuser if I were you.

ERROR


921 Fuser Error Indicates that the fuser is below standby temperature when the printer is idle.
Error codes 920, 921, and 922 may display for a cold fuser failure. A 920 error caused by low line voltage can sometimes be cleared by turning the machine off and then on again.
Service Tip: Set the Fuser Temperature to NORMAL before starting this service check.
Manually spin the fan and check that
it rotates freely. Check the cable
connection to the engine board, J13
for correct installation.
