− Equipment and parts will perform within published specifications. Promised or implied statements by any
Avery Dennison employee or representative will not be deemed to vary the terms of the warranty.

− Equipment and parts must be installed and operated according to recommended procedures and
operating conditions.

− Consumable elements are not covered. Consumable elements are those that show normal wear from
typical equipment usage including, without limitation, printheads, knives, rollers in contact with the web,
and sonic units. Avery Dennison reserves the right to determine which elements are defined as
“consumable.”
