A method of sealing a toner opening port of a printer cartridge, the method comprising inserting a seal through a toner exit port, the toner exit port leading to the toner opening port, the toner exit port being configured to be covered by a toner exit port plug, the seal comprising a seal frame and a first pull tab attached to the seal frame with a first adhesive, the seal further comprising a second pull tab attached to the seal frame with a second adhesive, the second adhesive being a different type of adhesive from the first adhesive; allowing the first pull tab to cover the toner opening port; detaching the second pull tab from the seal frame; and applying pressure to the seal frame thereby allowing the second adhesive to attach the seal frame to the printer cartridge, wherein the first pull tab is configured to be detached from the seal frame without substantially adhering to the toner exit port plug.
