Netbackup does not see cleaning tape in access port

I have inserted a new cleaning tape into access port. When I try to inventory robot with "Empty media access port prior to update" option checked, Netbackup seems not to see cleaning cartridge. I get the message "Volume configuration is up-to-date with robot contents.".

Master and Media are Windows 2008 Server R2

Master and Media Netbackup version is 7.5.0.6.

Robot is IBM TS3500 3584 L232. We have 10 LTO6 ULT3580-TD 6tape drives, drive type HCART3

Barcode rule is: Tag CLN, Media Type hcart3_clean, Voume Pool NONE

Cartridge barcode is CLNU75L1

All library slots are licenced and there are free slots.

I have tried some forum articles with no success.

Some one can help me?
