Abstract

Computer printers are expected to operate continuously, without interruption, for extended periods of time. However, many printers require frequent operator intervention because of limited paper tray and stacker bin capacity. In order to allow the operator to perform other tasks and yet intervene at the machine when necessary, some form of machine status indicator is desirable.

Computer printers are expected to operate continuously, without interruption, for extended periods of time. However, many printers require frequent operator intervention because of limited paper tray and stacker bin capacity. In order to allow the operator to perform other tasks and yet intervene at the machine when necessary, some form of machine status indicator is desirable.

Thereois proposed here an indicator 5 that would display the machine status around a 360 arc and which would be visible from any point in the room. The indicator 5 consists of a 3-segment, 3-color light mounted on a retractable stalk 7 attached to the printer 4 so as to project thereabove. The stalk 7, which would be retracted for shipping, would be set at any convenient height by the operator. Indicator 5 would preferably include a green segment 8 to indicate that the machine is operating normally, a yellow segment 9 to indicate an impending halt, and a red segment 10 to indicate a machine halt.

Indicator 5 could optionally be combined with an audio signal generator to attract attention on a change in printer operating condition.
