Abstract

A copying machine (10) includes copying circuitry (14) controlled by a copier processor (12). The copier processor (12) gathers and generates status information for the copying machine (10) and this status information is transmitted to a remote processor by a wireless transceiver (18). A transceiver processor (16) may be used to analyze the status information and control operation of the wireless transceiver (18). The wireless transceiver (18) may also receive information and corrective action in response to the transmitted status information for use by the copier processor (12) in controlling operation of the copying circuitry (14). A monitoring network can be formed using a plurality of copying machines (10) that send status information to a base processor (22) through a base transceiver (24). The base processor (22) can initiate appropriate action in response to received status information. A store and forward repeater (26) may be used to allow the base processor (22) to communicate with copying machines out of range of the wireless transceiver operational area.

Claims

1. A device for making photocopies, comprising:

a copier processor for gathering and generating status information regarding operation of the device;

a wireless radio frequency spread spectrum transceiver for transmitting said status information over a wide geographic area and for receiving diagnostic control information sent from said wide geographic area to control operation and provide corrective adjustments for the device through said copier processor, said wide geographic area including a radius of fifty miles from said wireless radio frequency transceiver.

2. The device of claim 1, further comprising:

a transceiver processor for analyzing said status information to determine whether said status information is to be sent by said wireless radio frequency transceiver.

3. The device of claim 2, wherein said transceiver processor converts said status information into a code for transmission by said wireless transceiver, said code uniquely identifying the device.

14. The device of claim 1, wherein said wide geographic area includes a radius of 50 miles from said wireless radio frequency transceiver.

15. The device of claim 1, wherein said status information includes malfunction indications, toner indications, paper jam warnings, and adjustment requirements.

4. A copier monitoring network, comprising:

a wireless base spread spectrum transceiver for receiving status information sent from within a wide geographic area and transmitting diagnostic control information within said wide geographic area in response to said status information;

a base processor coupled to said wireless base transceiver for analyzing said status information and generating said diagnostic control information for said wireless base transceiver in response to said status information;

a plurality of copying machines within said wide geographic area, each copying machine including a copier processor for gathering and generating said status information regarding operation of a corresponding copying machine, each copying machine including a wireless copier spread spectrum transceiver for transmitting said status information to and receiving said diagnostic control information from said wireless base transceiver, said base processor and said wireless base transceiver being at a geographically remote location from each copying machine within said wide geographic area, said wide geographic area including a radius of fifty miles from said wireless base transceiver.

5. The network of claim 4, wherein each copying machine includes a transceiver processor for analyzing said status information to determine whether said status information is to be sent by said wireless copier transceiver.

6. The network of claim 5, wherein each transceiver processor converts status information from a copying machine associated therewith into a separate code for transmission by a corresponding wireless copier transceiver, said code including information to uniquely identify said copying machine associated therewith.

7. The network of claim 4, further comprising:

a store and forward repeater within said wide geographic area for relaying said status information and said diagnostic control information between said wireless base transceiver and a copying machine located outside said wide geographic area.

8. The network of claim 7, wherein each store and forward repeater includes a wireless relay transceiver and a relay processor for controlling said wireless relay transceiver.

9. The network of claim 8, wherein said store and forward repeater connects directly to said base processor by wire communications.

16. The device of claim 4, wherein said wide geographic area includes a radius of 50 miles from said wireless base transceiver.

17. The device of claim 4, wherein said wireless copier transceiver transmits said status information without receiving requests from said wireless base transceiver.

10. A method of monitoring a copying machine, comprising the steps of:

generating status information within the copying machine regarding operation of the copying machine;

receiving said status information from the copying machine through wireless spread spectrum radio frequency communications transmitted over a wide geographic area, the wide geographic area including a radius of fifty miles from the copying machine.

11. The method of claim 10, further comprising the step of:

initiating appropriate corrective action in response to said status information.

12. The method of claim 11, further comprising the step of:

analyzing said status information to determine whether said status information should be transmitted from the copying machine.

13. The method of claim 12, wherein said initiating step includes transmitting diagnostic control information to the copying machine by wireless communication from a geographically remote location in order to perform said corrective action.
