That report is in the service menu. Do you know how to get in there? If not then you may want a service manual as well. Very handy to have.
If not and for others finding this thread: For CJ500,SC500,FJ 42,52 etc Some slightly newer Roland printers are similar by doing the letters in reverse order.
While printers front panel power button is off but main power switch on do the following on the arrow key pad. It's like an "s" and "v" shape to remember easier.
up,left,right,down, left, down, right and after that hold all three (left,down,right) and power on. If you get the error message try again. Once that works press menu and arrow over to the service menu.
