There are 2 methods for entering SP mode on most Ricoh printers. It used to be in the service manual but not any longer. The following is from the manual for the CL7000:

Method 1: Turn the machine on while pressing the On Line key and Escape key together until the above message in the illustration appears on the display.
NOTE: If you switch the machine off, any jobs stored on the hard disk using the sample print and protected print features will be deleted. Check first with the user tools to see if there are any jobs stored with these features(Menu key - Sample Print, or Protected Print).
Method 2: Press the Up/Down arrow keys together for about 5 seconds, then press the Enter key. The above message shown in the illustration appears on the display.
NOTE: The machine automatically goes off line when you enter the service program mode.
