SETTING UP PRINT JOB SOURCES
• Do not write on a tape cartridge label while it is on the
cartridge. If you want to change a label, write a new label,
remove the old label, and replace it with the new label.
Write protection of cartridge tapes
An 18-track cartridge tape has a thumbwheel on the side of the
cartridge for write protection, as shown in figure 3-2. Write
protection prevents the system from writing data onto the tape.
This protects the data on the tape from accidental erasure.
Figure 3-2. 18-track cartridge tape write protection
To enable write protection (prevent data from being erased), turn
the thumbwheel so that the white dot is showing in the window.
To disable write protection (allow data to be written to the tape),
turn the thumbwheel so that the white dot is not showing in the
window.
In most cases, you do not need to write data to a tape when
running print jobs, so it is safer to enable write protection before
loading tapes.
Loading an 18-track cartridge tape
Follow these steps to load a 18-track cartridge tape:
1. Inspect the cartridge for visible damage.
For more specific information on checking for signs of
damage, refer to the guideline for handling tapes at the
beginning of this section.
CAUTION: Loading a damaged tape can damage the tape
drive and result in data loss.
