SETTING UP PRINT JOB SOURCES

5. Insert your index finger through one of the holes in the fixed

reel to hold the leading edge of the tape firmly against the
center of the reel.  Wind the reel clockwise until the tape
laps over enough of itself to be secured to the reel.

6. Once the tape is secured, continue to wind the reel in the

clockwise direction to gently take up the remaining slack in
the tape path.  The tape is now threaded but not loaded.

7. Close the door to load the tape.

Note:  Until you close the door, the cover interlock in its
electrical sensing system continues to disable the command
switches on the operator control panel.

8. Press the Load Rewind switch on the operator control panel.

The BOT indicator lights as soon as the beginning of the tape
is found.

Note:  If the tape drive cannot find the BOT within 25 feet
(7.62 meters) in the forward direction, it reverses to search
for it.  If the tape drive cannot find the BOT in either
direction, it stops, and an error status code appears in the
two-digit LED display on the operator control panel.

You must now place the tape drive online to the LPS.

Follow these steps to place a tape online:

1. Press the On Line switch to place the unit online to the

system controller.  The switch may be pressed while the
loading operation is in progress.  When the online indicator
lights, loading is complete.  The tape is now threaded and
loaded.  You are ready to start jobs.

Note:  If the online indicator does not light when you press
the switch, refer to the “9-track magnetic tape drive on the
controller cabinet problems” section of the “Solving
problems” chapter.

2. If your LPS is connected to both a 9-track magnetic tape

drive and an 18-track cartridge tape system, you must tell the
printing system which tape drive you intend to use.  You do
