Previously answered by AndyBell Error code sc542

this is an error for the fuser heat up..the temp is not being maintained or fluctuations.

try this -
press the yellow clear button at top of number pad then enter 107 and hold down the red cancel button..the screen will change

enter the copier sp and select 5.mode arrow down to 5-810 sc reset and execute.

turn machine off..

if the code disappears it could have been just a glitch

if not check the fuser to see if there is heat coming from it

the lamps will come on at the start up.

you can check this by putting a screw driver in the actuator slot to cheat the door switch

if you see the lamp come on then you may just have to clean off the thermistors ..

open the fuser up with the top screws and check that there isn't any build up of toner on thermistors..

hope this helps

my dear you first yellow baten press after you sclet 107 after you press stop 2 sc

slide the pcu out - clean around it and clean the contacts inside then put back in - i
