Really FixYa, how about FukYa?

Error code 021 indicates a bad fuser but in some cases, the error can be reset. To attempt a reset, do the following:

1. Remove the toner cartridge and close door back up.
2. Power down the fax (switch is on the back side lower left) for 5-10 seconds.
3. Power on the fax and see if the 021 code is gone.
4. Re-insert toner cartridge

If this doesn't work, there's one other thing to try prior to calling a technician.

1. Push the function button
2. Push 7 on the key pad
3. Push Monitor button 4 times (it will only beep at you)
4. Push * on key pad

You should now see the service menu option

5. Push 7 on the key pad
6. Push "Set" button
7. Push down arrow button once

You should now see the fuser reset option

8. Push "Set" button

You will be prompted for 1 for Yes 2 for no

9. Push 1 on key pad.

You should receive confirmation that the reset is *COMPLETE*

10. Push Stop button until back to the main screen

11. Power down the fax
12. Wait 5-10 seconds.
13. Power on the fax

If this doesn't work, a service call will be needed to replace the fuser. I do hope this fixes your problem.
