SOURCE: Clear code FK3 on a

Code FK3 means that the fuser web cleaning counter has reached the specified limit. Replace the web and reset the counter.

FK3 is an expired Fuser Web Cleaning Kit (150K life). The MX machines automatically go into Offline status as there is a maintenance due. You must replace the Fuser Web Kit to prevent damage or extra wear on the Upper Heat Roller as well as help clean the Lower Heat Roller. The kit is available as MX450WC or NROLR1576FCZ2 as a spare part.

You can set Sim 55-03 Switch 9, Bit 5 from 0 to 1 to prevent Windows Spooler detecting a maintenance status, therefore enabling the machine to continue online (You still must do the maintenance though).

There is no offline/online button. The machine will always be online as long as there are no maintenance issues due at the time.

Do the maintenance ASAP to clear this. You will need to reset Web counter & Sub-Heater counter E.

Hope helps.
