Symptoms

Unreadable label at mail slot 2 and 3.

Only located in mailslot 2 and 3 carts were unreadable but these cart labels could be read on mailslot1 and 4 and all magazines. These 2 carts could be moved to any slots but cart states were still unreadable. Any carts could be moved to mailslot2 and 3 without any problem and cart states are readable (labels are displayed).

All carts were properly read by SL8500, SL3000 and SL500.
