Servise mode

i want a simulation code for sharp AR-M160

different models use different display methods, if there is any sort of touch screen it will appear there in an alpha-numeric display
eg U4-2 or J3-2 etc.others just display symbols if there is no touch screen (symbols like a pyramid of dots for out of toner, crossed circle for drum end of life etc) some of those will display a number if you hold down the clear button or the stop button, depending on the model
there are probably 5 or 6 different diagnostic systems needing different entry modes...you will have to be very specific with both the code and the model number of the machine

error code sc818 . how to fix this error.

What is the model number?
