Now tap on the trouble reset button and it hould point down an arrow saying OK. Now shut down the machine again and leave it off for at least 10 seconds.

2.Use the “Up/Down arrow” keys to scroll through the menu listing.
3. Press the (OK) key while on the display writes " 2. Engine " .
4.go to "[5810 001] - Fusing SC Reset" by scrolling the “Up/Down arrow” keys and press the [OK] key (on the display should write execute or done) press [OK] again if is needed to press it.
5. After this turn off and than after 5 second turn it on the machine.
Please do not change nothing else in this menu only reset the fusing unit SC code, because if you change some other values and settings you might to regret that and pay high price for that.
So only reset the Fuser SC code SC542 by the upper mentioned method and do nothing else, if the SC code appear again then do not try this again because you might burn some parts.
If this do not help than call the technician.

this is a low fuser temerature code you can reset it by the following method:
1. on the right side of the machine there is a small cover you can remove next to the network card it just clips on pull down on the small lever and pull it down
2. once the cover is removed you will see a connector and a small hole with a switch in it to the right of the connector push the switch with a small object like a ball point pen.
3.when a small dot appears on the touchscreen hit the number 3 on the number pad.
4.enter the 8 digit service code which is 00000000 and touch end.
5. select trouble reset to reset the error code.
if the error code reccurs you will need to replace the fuser unit but i have seen the machines show this error when they are turned on while the room temp is cold first thing in the morning.
