Abstract

In some parts of the world, AC power is unreliable and may regularly be cut off on a rotating basis or subject to frequent outages. This idea proposes enabling a Multifunction Device (MFD) to offer limited but useful functionality when AC power is unavailable by selectively powering certain functions from an external power source. This capability could allow users to work more efficiently in power outage situations. A portable device may be able to supply limited power via a Universal Serial Bus (USB) connection, or a battery and power inverter may be available. With this capability, users can perform operations such as print job queuing, grouping, and prioritization at any time. Then printing can begin when power is restored. Other functions, such as FAX, may be possible when working with limited power.

Multifunction Device operation using alternative power

In some parts of the world, AC power is unreliable and may regularly be cut off on a rotating basis or subject to frequent outages.  This idea proposes enabling a Multifunction Device (MFD) to offer limited but useful functionality when AC power is unavailable by selectively powering certain functions from an external power source.  This capability could allow users to work more efficiently in power outage situations. A portable device may be able to supply limited power via a Universal Serial Bus (USB) connection, or a battery and power inverter may be available. With this capability, users can perform operations such as print job queuing, grouping, and prioritization at any time. Then printing can begin when power is restored. Other functions, such as FAX, may be possible when working with limited power.

Currently, all functions of an MFD depend on its own the power supply and the availability of alternating current power from the supply grid.  This idea suggests enabling a limited set of functions when the traditional power source is not available.  This idea also proposes enabling the system to operate using an alternative power source.  The alternative power source could be via a USB connection from a mobile device (laptop or tablet computer) or a battery and power inverter.  This power would not provide full functionality but would be sufficient for certain limited functions like scan to USB or faxing.
