Cleaning the Tape Path
The drive will display a *CLEAN message and display a CLEAN
ICON after processing a predetermined amount of tape, or when
reaching certain conditions. If this message is displayed, clean the
drive tape path immediately to keep the drive in good operating
condition.
Model B11/E11
Separate cleaning procedures exist depending on whether you clean the tape
path in Random mode or the other modes.
v To clean the tape path in Random mode, at a time that is appropriate for
the software application, use the operator panel to change the ACF mode
from Random mode to Manual mode. Ensure that no cartridges are loaded
in the drive before changing to manual mode. Manual mode operations
from the priority cell do not require unlocking of the magazine. Insert the
cleaning cartridge into the priority cell.
Cleaning cartridges automatically export to the priority cell when the
cleaning is complete. At that time, change the ACF mode back to Random
mode. The operator may choose to vary the drive offline during the
cleaning period. The software application may inventory the ACF again at
this time. Optionally, the software application may also re-verify the
cartridge’s internal labels by reading the cartridges.
v To clean the tape path in Manual, Accumulate, Automatic, or System
modes, place a cleaning cartridge into the priority cell. The drive
automatically loads the cleaning cartridge. The cleaning cartridge completes
its cycle, then unloads into the priority cell.
