At the top of the test is the printer type (1), emulation (2), country (3), and firmware revision
level (4). This information is often required while performing service or when contacting
Okidata. Have this test available during your service call.
CAUTION
Running the test without paper loaded will allow the printhead to print on the platen.
This will dirty the platen, cause excessive wear of the ribbon, and may damage the
platen, ribbon, and printhead.
