Test Pattern Printing - Ricoh G147 Service Manual

5.3 TEST PATTERN PRINTING

Test pattern printing is a two-step operation. First, you must do SP2902 to select the pattern
that you want to print. If you select any pattern other than "0:None" under SP2902, this sets
the printer in the Test Pattern Print mode. Second, you must do SP5990 005 to print the
pattern.
You can select any selection under SP5990 to print the selected pattern. However,
SP5990 005 (Diagnostic Report) is recommended because it prints only one page. If
you select "001", for example, several copies of the same pattern may print.
The printer will remain in the Test Pattern Print mode until you leave the SP mode or the
printer power is turned off and on. (If you leave and reenter SP mode or turn the printer
off/on, this automatically reselects "0:None" for SP2902.)
The normal SMC report lists done with SP5990 will not print until the printer has been
released from the Test Pattern Print mode.
