Optional Coaxial/Twinaxial Interface
Page C-9
Code Dump Mode (Address 0 through 6)
The code dump diagnostic allows you to print in hexadecimal format all data received by the
coaxial/twinaxial interface.
First line - The printable representation of the received EBCDIC character.
Unprintable characters (such as form feeds or nulls) will print as spaces.
Second line - The most significant nibble of the received EBCDIC character printed in
hexadecimal format.
Third line - The least significant nibble of the received EBCDIC character printed in
hexadecimal format.
For Example:
F K A H D EBCDIC character received
02C002D02002C02C0403C0 Most significant nibble
CB629B2490FB11B8301441 Least significant nibble
This above example shows the printer receiving a Form Feed (0C) followed by a
system command to go to 8 lpi (2B C6 02 09).
Configuration Printout (Address 7)
This diagnostic provides you with a one page printout which describes the current
configuration.
Print Test (Address 8)
Selecting this diagnostic causes a test pattern to be printed. This tests the internal interface to
printer electronics connections.
Loop Test (Address 9)
This diagnostic tests the internal interface electronics. When performing this test, the coaxial
or twinaxial adapter cable must be attached to the printer, but not connected to the host
computer. When complete, a “Loop test passed” or “Loop test failed” message will be
printed.
Diagnostic Problems Checklist
If the printer's built-in diagnostic tests do not perform as described above then:
a. Verify the printer configuration.
b. Check all of the installation connections.
c. Rerun the diagnostic. If the problem persists, contact your dealer or Printek
Technical Support for technical assistance. If possible, have the configuration
printout from the Address 7 diagnostic available when you call.
