5.2.2 Printing Self-Test
The LG31 printer can execute a printing self-test from either the outer
or inner control panel. This test prints the 94 printable characters of
the ASCII character set in the data processing font, at 10 CPI, and 6
LPI. The test is printed in a swirl pattern over the maximum printable
width (see Figure 5–1). Faults are displayed at the control panel. Table
5-1 contains the procedure for an off-line print test. Table 5-2 lists the
diagnostic fault codes.

5.2.3 Operational Self-Test

intervals during normal operation. Any detected faults are displayed on
the control panel.
