2.Turn the power switch off, then hold down the DRAFT button on the control panel while you turn the power back on. The Apex80 begins printing letters, numbers, and other characters that are stored in its ROM (Read Only Memory) in draft mode. (If DIP switch 1-5 has been turned on, the test will be performed in NLQ mode, as in step 4 below.)

3.When printing starts, you can release the DRAFT button; the printing continues until you turn the printer off or until the printer runs out of paper.

4.To perform the same test in the NLQ mode, load another sheet of paper. Turn the printer off, then turn it back on while holding down the NLQ button. Sans Serif and Roman fonts alternate for this test. Partial results of both tests are shown in Figure 1-20.
