Cause

Error in fuser swing arm function

Resolution

First thing to do is to restart machine by powering off main switch leaving for a minute to sit and restart. Machine reinitialisation may clear this error and you can work away

If a machine reboot does not stop error from reoccurring, restart machine in service mode

(Open the foot door, power off the main switch, hold down the "Utility/Counter" key on the keypad, power on and keep holding the key until the machine boots up in service mode, close the front door)

Then

• Select Option 3 , (System Setting )
• Select Option 1 , (Software DIPSW )
• using arrows change the left most number to 36
• using arrows change middle number to 1 (161-1 for 3070)
• select the right most setting to OFF

Exit out of this section and keep exiting/closing out of service mode and machine will restart and warm up again.
