ABSTRACT:
A method of sealing a toner opening port of a printer cartridge is provided for inserting a seal through a toner exit port leading to the toner opening port which is configured to be covered by a toner exit port plug. The seal has a seal frame and a first pull tab attached to the seal frame with a first adhesive, and a second pull tab attached to the seal frame with a second adhesive, the second adhesive being different from the first adhesive. The method further provides for detaching the second pull tab from the seal frame, allowing the first pull tab to cover the toner opening port, and applying pressure with a seal clamp to the seal thereby allowing the seal to attach to the printer cartridge.
