Method for sorting form stacks in a storage system and removing the form stacks from the storage system, the form stacks (8) being produced by passing a continuous form web (1) through a printer (3) wherein the form web is printed, the forms (2) obtained being stacked to provide form stacks (8) which are fed to the storage system (11) for sorting therein, characterized byidentifying each form stack (8) with regard to the identity received during manufacture thereof;

  • storing the information received regarding the identity of the form stack (8);

    comparing the information received regarding the identity of the form stack (8) with stored information regarding the identities of one or more form stacks (8) sorted in the storage system (11);

    sorting form stacks (8) with a certain identity in such compartments in the storage system (11) containing a form stack or form stacks (8) with the same identity if, during the identity comparison, it is determined that there is/are one or more form stacks (8) with the same identity in a certain compartment in the storage system (11);

    sorting form stacks (8) with a certain identity in a free compartment in the storage system (11) if, during the identity comparison, it is determined that there is/are not one or more form stacks (8) with the same identity in the storage system; and
