I have a richo 2018d all in one copier machine it can be a error code SC541.
what is its solution ....

I do not recognize either of these codes (187 or 387) as part of the Aficio 2015 error list.

If the code is displayed on the screen, physically TURN OFF the copier with the main switch (red switch), wait 10 seconds and turn it back on. If it's an erroneous error, this should reset the error code. NOTE: THE ERROR CODE MUST BE DISPLAYED FOR THIS TO WORK.
