Abstract
Abstract A self service printer is improved by providing for temporary storage of several printed documents to be issued as a bundle. An opening in the housing for the printer is normally closed by a pivotable cover behind which documents are accumulated and stored, a first set of transport rollers including drive and pressure rollers is arranged behind the cover and being provided for cumulatively holding and moving one or more individual documents; second set of transport rollers is disposed upstream from the first set of rollers and operated in opposition such that the first set provides for holding or transport and the second set is open and vice versa; a control device operates the cover and said transport roller sets and provides (i) a closed disposition of said cover in an open position for said first set of rollers permitting insertion of documents in between through the second set, (ii) a closed disposition for the cover as well as closed disposition of the first transport roller set for holding and storing documents in between, and (iii) providing issuance of the documents for open cover and closed first set of transport rollers, said transport rollers then being driven; the second set is open during (ii) and (iii).
