|  | B41J |
Note(s) This subclass covers: manually controlled power-operated apparatus or apparatus of this type with additional control by input of recorded information, e.g. on punched cards or tapes; the "print-out" features of apparatus controlled by record carriers or electric signals in so far as these are of general interest, e.g. impression, inking, line-spacing mechanisms, printing heads. [5] This subclass does not cover: electrical features of apparatus controlled by record carriers or electric signals and of interest apart from the "print-out" features of said apparatus; apparatus controlled by record carriers or electric signals, as a whole. [5] In this subclass, the following term is used with the meaning indicated: "paper" covers also similar flexible copy material; [3] "printing material" covers both paper and temporary record carriers from which records are transferred to a paper, but does not cover printing masters, e.g. formes.

|  | B41L |
Note(s) This subclass does not cover constituent parts common to manifolding by means of pressure-sensitive layers or intermediaries, to apparatus or machines for duplicating or printing for office or other commercial purposes, or to addressing machines or like series-printing machines, which are covered by subclass Fulltext... Hierarchy... Expanded...B41F. In this subclass, as indicated by the references, groups Fulltext... Hierarchy... Expanded...B41L 15/00 and Fulltext... Hierarchy... Expanded...B41L 17/00 are intended to cover letterpress and lithographic printing apparatus only in so far as it is specially adapted for office or other commercial purposes; the general constructions or features of apparatus of these types are classified in subclass Fulltext... Hierarchy... Expanded...B41F. Constructions or features determining classification in these groups are, for example: ease of operation by clerical staff, cleanliness of operation in non-industrial environments, the use of printing surfaces constructed for the production of a limited number of copies. In this subclass, the following terms are used with the meanings indicated: "manifolding" means the obtaining of several copies simultaneously by means of pressure-sensitive layers when making an original; "duplicating" means the obtaining of successive copies from a master, e.g. a hectographic image; "stencilling" involves the use of a printing surface which is perforated to form the image, the ink flowing through the perforations on the copy material.
