A more intuitive and easier to use repositionable sheet stack edge guide, in which a single simple manual movement of a single visible upstanding member in either of the opposite possible repositioning directions can both automatically unlatch the edge guide latching system from its previously latched position by the partial pivoting of that member and also move the edge guide in its desired repositioning direction.

Simplified movement printer sheet stack edge guide

A digital printing apparatus is capable of a plurality of selectable output speeds, by varying motor speed or pitch configuration. A user using the apparatus at a basic speed can request a temporary increase in speed of his printing apparatus from a vendor who controls aspects of the printing apparatus over a network. The temporary speed increase can be pre-scheduled, such as to occur one day per week. The user can be charged at different per-print rates depending on the selected speed.

Digital printing apparatus with remotely selectable operating speeds and features

A basic hardware platform of a copier or printer is selectably enabled to operate at different speeds, such as 40 ppm or 30 ppm, by a combination of entering a password into non-volatile memory within the machine, and also altering a state of a hardware switch within the machine.

System for enabling a printing apparatus to operate at multiple selectable speeds

In a reproduction system providing an ordered output from a printer to a sheet output stacker of printed transparency sheets interleaved with corresponding paper sheets, with a choice of different output stacker units to be operatively connected to the printer, wherein at least one stacker provides face down stacking, and at least one other provides face up stacking; an automatic electronic printing order control system is automatically electronically activated by the connection of a stacker unit to the printer to change the ordered output of printed transparency sheets and paper sheets so that the transparency sheets will be ahead of their corresponding paper copy sheets regardless of which stacker is connected to the printer. In this example, paper sheets are outputted followed by their corresponding transparency sheets when a non inverting output unit with face up stacking is connected, and the transparency sheets are followed by their corresponding paper sheets when an output stacker with face down stacking is connected, which in this example is a sheet inverting stacker module.

Printing system for automatically delivering transparencies and regular

An automatically self-aligning charging device assembly for producing a layer of charge on a charge holding surface in alignment with a document registration position on the platen of a machine. The assembly includes a charging element having a start-of-charging position thereto, and a housing enclosing the charging element. The assembly also includes a stop member mounted to the frame of the machine at a first side of the platen for contacting a first end of the housing at a desired point so as to automatically align the start-of-charging position of the charging element with the document registration position. A resilient force applying member connected to a second end of the housing automatically absorbs corrective adjustments to a location of the start-of-charging position of the charging element relative to the document registration position on the platen, thereby automatically aligning the start-of-charging position with the document registration position.
