1. Connect the machine to another fax terminal back to back (connect them directly, without using an ex-
change or any type of switching device).
2. Set bit 7 of G3CCU bit switch 40 to 1.
3. Place the other fax machine in back to back mode. For example, if it is another FAX7000L, set bit 7 of
G3CCU bit switch 40 to 1. See the machine’s field service manual for details.
4. Place a document in the feeder of one of the machines and press Start on that machine.
5. Press Start on the other machine.
6. Check that the document is transmitted correctly.
7. Repeat the test, but send the document from the other machine.
8. After testing, reset bit 7 of G3CCU bit switch 40 to 0. Also, reset the other machine to normal operating
mode.
Note: There is no need to use a battery to supply line power for the test.

In most cases, if the system software crashes, the machine can be reset by holding down the Stop key for
about 10 seconds. If that does not work, switch power off, wait a few seconds, then switch back on.
