Troubleshooting 3-33
The startup screen features the following elements:
• A conventional-looking Menu Bar across the top of the screen;
all diagnostic functions are accessible via this menu.
• The middle of the screen is a blank gray area; this is a 23 x 80
“tty” in which all interaction takes place with the tests when
they are running.
• The bottom line of the screen gives feedback about the state of
the system. It is divided into four fields:
•• The left-most, and largest field is the “message” field. It
contains descriptive text summarizing the operation of
tests in progress and of the diagnostics program itself.
•• Next is the completion indicator. When downloading test
files to the printer, this field indicates the progress of the
operation with a percentage-complete display “n%”
(where n is 0 to 100). When running a lengthy series of
tests, a display “n of N” indicates the test progress.
•• Third is the “view” field. This indicates which “channel”
is being viewed in the tty screen. The 29K channel
displays information related to the communication line.
The 68K channel displays information related to the
printer and the diagnostic tests.
•• In the bottom-right corner is a tiny field which indicates
the status of the communication link between the PC
and the printer’s processor. It says “OK” when the link is
working and “NO” when communication is lost.
Selecting Tests
Press Alt-T or move the highlight block to the Tests pull-down menu
and press Return to activate the test selection window.
Use the following keys to navigate the lists of tests. The left column,
Test Suites, lists the groups of test. The center column shows the
individual tests within a selected test suite. The right column,
“Status,” indicates if a test is selected. You can select a single test, a
series of tests, or all the tests is a test suite.
In the Test Suites column:
• Up and Down arrows – Move the Test Suite selection
highlight block up or down on the screen. When the highlight
block reaches the top or bottom of the screen, it causes the list
to scroll if there are more tests in that direction on the list.
• Tab or Right arrow– Activates a suite of tests. The individual
tests of the selected test suite are displayed in the Individual
Test column.
