摘要： A print media handling system for a compact printer having a housing, a cut-sheet supply station, a rotatable print platen constructed and located to feed top sheets from the supply station, through a print path ingress and out a print path egress. The sheet supply station of the print media handling system is mounted for movement to and from a sheet engaging relation with respect to the print platen. A continuous print-media inlet passage extends from a location, that is spaced from the sheet supply station, to the print path ingress and an actuator is provided synchronously enable the supply station and block the continuous media inlet passage, or vice versa. A first program control effects a predetermined start-print sequence for sheet print media, a second program control effects a predetermined start-print sequence for continuous print media; and the first or second program control is selected in response to the condition of the actuator.

摘要： A printer/feeder apparatus of the type having: (i) a feed/transport platen rotatable so that its peripheral surface moves past a sheet supply zone, a print path ingress, a print zone and a print path egress; (ii) frictional feed surface located on a peripheral sector of the platen surface and (iii) means for selectively effecting feeding engagement between the face sheet(s) of a stack of sheet media and the feed surface features a detection/control system that includes (a) a first detector for sensing and signalling when and when not a forward edge of the feed surface is at a predetermined start position; (b) a second detector means for sensing and signalling when and when not engagement condition exists; (c) a third detector means for sensing and signalling when and when not a sheet is located along a predetermined portion(s) of the print path; and (d) a control system for receiving signals from the detectors and enabling printing cycles and signalling error conditions.
