hexadecimal printing begins (there may be a delay while the printer finishes
printing previously formatted data from the buffer).

8.3 Self-Diagnostics

The Laser Card has an additional twinax test to aid in the diagnosis of problems.
You can set up the interface to perform a complete analysis of its functions. The
interface transmits data to itself and then analyzes how that data is processed. If an
error is detected, an error message is printed on the printer. Otherwise the
interface prints the following message:
TEST SEQUENCE COMPLETE
The diagnostics repeat continously. The Laser Card will fill up the entire test
report page, which can take several minutes.
Power the printer OFF to end the testing.
Any error messages are printed between the "TEST SEQUENCE COMPLETE"
messages.
The twinax host must not be connected to the V-connector during this
test.
