1. The first thing displayed after the printer is turned on or at the
conclusion of an ASCII print test, is [.8.8.8] accompanied by audio
alarm sounds for approximately two seconds. The [.8.8.8] display
allows verification that the display LEDs (three decimal points and
21 segments that form the [.8.8.8] display) are all functioning.
2. The printer then displays[iP]forseveral seconds, indicating that
the printer self-test is in progress. The display then changes back to
[.8.8.8] for several seconds.
3. If necessary, the display then shows [SUS]forseveral seconds
indicating printing is suspended until the ribbon weld moves past
the striker bar.
4. When the printer successfully completes the self-tests, it enters the
Off line (printer display is[OFL])ortheOnLine (printer display is
[ O n L]) mode. The power-up mode is dependent on printer control
Strap 24.
NOTE
Any display other than those described in steps 1through 4 may
indicate a diagnostic self-test failure, or an operator correctable
fault. In this case, proceed directly to Section 5.2.3 for error
code identification.
5.2.2 Diagnostic Self-Test Sequence
The diagnostic self-tests are a series of 27 tests; which exercise several
of the printer’s key FRUs. If an FRU fails, an error code is displayed.
This means that if a fault code is displayed, all tests prior to the fault
were good; however, tests following the error code may have errors.
Table 5-2 shows the sequence of diagnostic self-tests and the FRUs each
test addresses.
