Samsung clp-610 has an error code of ''adc slope error cycle power'' what does this mean? How can we rectify the problem?

this would be a problem with the fuser unit. the analog to digital converter, ADC, is malfunctioning or there is a problem with the heat being put out by the fuser itself. if cycling the power doesn't clear the problem you will more than likely have to replace the fuser unit.

Have lsu error also.

Hi ...

LSU stands for Laser Scanner Unit ... you normally get 2 different kind of errors with LSU ...
LSU Hsync or LSU Motor Error ...
If you get this error, it means that the Laser Scanner Unit has gone bad and the only way to get it fixed is to get the printer repaired ...

Cheers ....
