Clean Now
C
The tape drive needs cleaning:
1. If the operation has stopped, eject the
tape and clean the drive.
2. If the operation has not stopped, wait for
it to finish and then clean the drive.
Check the tape drive users manual for
device specific cleaning instructions.
The drive thinks it has a
head clog, or needs
cleaning.

Invalid cleaning
tape
C
The last cleaning cartridge used in the tape
drive was an invalid type:
1. Do not use this cleaning cartridge in this

fault that requires reset to
recover.
31
Hardware B
C
The tape drive has a hardware fault:
1. Turn the tape drive off and then on
again.
2. Restart the operation.
3. If the problem persists, call the tape
drive supplier helpline.
The drive has a hardware
fault that is not read/write
related or requires a power
cycle to recover.
