COMPATIBLE COPYING OF COMPUTER FORM DOCUMENTS

摘要

Automatically feeding document pages into registration over the conventional platen of a copier wherein the document pages comprise single page individual sheets and plural page connected unseparated segments of elongate computer forms webs, comprising: feeding the first document page automatically to the platen and registering it in an individual sheet document mode regardless of whether the first document page is an individual sheet or the first page of an elongate computer forms web; automatically sensing whether a computer forms web was so fed to the platen by sensing whether the document length exceeds a preset length and that said document has sprocket holes; and then automatically switching from said individual sheet document mode to a computer forms web document mode for the feeding and registering of subsequent document pages of a computer forms web in response to said sensing of a computer forms web, wherein in said computer forms web document mode the subsequent computer forms web page feeding and registrations are accomplished by incrementing the web in preset incremental feeding distances controlled by sensing sprocket holes in the computer forms web but with the same frictional (non-sprocket drive) feeder and without utilizing a mechanical registration gate; and wherein in said individual sheet document mode the individual sheet page registrations are by appropriately cycling a mechanical registration gate in and out of the document path.
