Corrective Procedures
Ensure that front door is securely closed.
Thread tape.
Check that the supply reel hub is latched, the Bar
marker is located correctly, or correct the tension
fault which occurred during the load operation.
If a tension fault occurred, the tape may be wound

not load) and press the LOAD button and then the
TEST button

reset the tension ofthe tape.
Refer to Figure 3-3 to ensure that tape is threaded
correctly.

with tape of known good quality.
RESET button was pressed inadvertently by oper-
ator. Reinitiate test.
Check for presence of a write-enable ring in rear of
supply reel. Install ring if one is not present.
Check for presence of Ear marker. Iffault condi-
tion still occurs, replace with tape
of
known good
quality.

Operator Diagnostic Test 01
Operator diagnostic test 01 must be run when specified in Table 4-1. Upon com-
pletion of the test, refer to Table 4-2 for corrective procedures.
When no errors are detected during diagnostic test 01, the test runs for approxi-
mately 13 minutes, if a 2400-ft, 10.5-inch tape reel is used. Test time varies with
other size tape reels. The test is interrupted and a numeric fault code appears on
the two-digit display when a fault is detected.
