An automatic paper handling system capable of loading individual sheets of a stack of paper onto a drum for printing or scanning, escaping a printing or scanning transducer relative to the drum, and stacking the sheet of paper after printing or scanning is additionally provided with duplexing capability to print or scan on the opposite side of a page of paper previously mounted to the drum without the requirement for manual reloading of the page by an operation. During unloading of the page after printing or scanning on a first side thereof a deflector path is interposed in the paper unloading path to cause the trailing edge of the paper during unloading to become the leading edge of the paper for a succeeding loading operation such that the side of the paper previously in contact with the drum will become the side of the paper exposed to the printing or scanning transducer.

There is disclosed a ribbon supply replacing technique for a printer or the like comprising a two ree coaxial ribbon cartridge (2) held stationary in the printer and having positioned adjacent thereto severing stations (40 and 42) for separating the cartridge with its exhausted ribbon supply from that ribbon remaining in the ribbon guide structure (6).

A method of making a plurality of multi-wire nonimpact printheads provides precise inter-wire spacing accuracy and repeatability of manufacturing steps to enable mass production. A plurality of slats are molded, one alongside another on a cylindrical support shell, parallel to the shell axis. A helical thread is engraved on the slats along the axial length of the support shell. A continuous wire is wrapped in the thread and the portions of the wire on the slats are encapsulated. The support shell and wrapped wire is cut between adjacent slats to obtain a plurality of printhead blanks. Each blank is machined to smooth the exposed print wires. The resultant printheads may be used in page- width nonimpact printers.

Disclosed is apparatus attachable to a printer for feeding and delivering envelopes. Storage means for fresh and printed envelopes which are disposed perpendicularly to the orientation of print direction. A reduction in overall size required in a mechanism for handling feed and delivery of both cut sheets and envelopes is achieved.

A modular design disc receiving apparatus that is utilized as a cartridge holder or output hopper. When utilized as a cartridge holder, push to latch, push to unlatch means position the cartridge for proper disc insertion, thereby readying the apparatus for its function as a cartridge holder. The apparatus comprises means for counting and giving visual indication of the number of discs ejected into the cartridge, and means for sensing a cartridge full situation, thereby enabling associated feeding systems, and, accordingly, preventing jamming of the apparatus. In addition, the apparatus is utilized as a disc output hopper, in the situation where a cartridge is not being used. When used, as aforementioned, the capacity of the apparatus is approximately doubled. Discs ejected into the apparatus are neatly stacked so that they protrude from the front of the apparatus where they can be seen and easily removed. When the apparatus is completely filled with discs, a subsequently ejected disc will be forced out of the apparatus to prevent jamming.
