Troubleshooting Tables - HP PageWriter XL M1705B Service Manual

The messages in the following list are Extended Self-test's failure
messages. If a subassembly test fails, the failure message for that
subassembly appears in the keyboard display. The message remains
there until you set the cardiograph to Standby (or it shuts itself off
to preserve the battery). Because the keyboard display is tested
entirely with a test pattern, there is no failure message for the
keyboard display test. Test pattern errors must be visually detected
while the test patterns are displayed. This is also true for the test
patterns displayed on the preview screen, the patient module display,
and the printer.

Tables
The troubleshooting tables in this section help you to localize a fault
and correct it. The troubleshooting flowchart in Figure G-2 guides
you to the troubleshooting table that covers a particular functional
area of the cardiograph.
Table 6-l lists errors that can occur only during the power-on routine
and will appear only as numbers on the display. The table defines
and explains each error, and suggests one or more corrective actions
for each. All the other tables list failure symptoms, possible causes,
and suggested remedies.
