Abstract

An image producing device such as a copier or a printer includes sensors for determining the presence of output from a previous job in the paper path or a finishing device. A particular operator'"'"'s access rights are determined through a login process. Depending on the operator'"'"'s access level, i.e., authority to view sensitive documents, the image producing device enables a purge of the existing sensitive documents or electronic images or prevents operation until an authorized operator initiates a purge.

Claims

1. An apparatus for preventing unauthorized disclosures of sensitive information in an image producing device, said apparatus comprising:

means for determining access rights of a first operator, said access rights indicating an access level of said first operator;

sensing means for sensing whether output from a previous job is present in said image producing device;

means for preventing operation of said image producing device in response to signals from said sensing means and said access level of said first operator; and

means for inhibiting clearing of said output from a previous job from said image producing device if said access level is less than a predetermined level.

2. An apparatus according to claim 1, wherein said image producing device has a paper path, said sensing means sensing whether outputs from a previous job is present in said paper path.

3. An apparatus according to claim 2, further comprising means for automatically purging said output in said paper path in response to signals from said sensing means and said access level.

4. An apparatus according to claim 3, wherein said means for automatically purging comprises means for directing said output to a waste box.

5. An apparatus according to claim 3, wherein said image producing device comprises a finishing device for finishing output of said image producing device, said means for automatically purging comprising means for directing said output to said finishing device.

6. An apparatus according to claim 3, further comprising means for recording an operator password in response to signals from said sensing means if said operator is logged off and output is present in said paper path.

7. An apparatus according to claim 2, further comprising means for enabling login of a second operator if said means for preventing operation prevents operation of said image producing device because of said access rights level of the first operator.

8. An apparatus according to claim 7, further comprising means for automatically purging said output in said paper path in response to an access level of said second operator.

9. An apparatus according to claim 8, wherein said means for preventing operation of said image producing device prevents operation while both the first and second operators are logged in.

10. An apparatus according to claim 9, wherein said means for preventing operation of said image producing device allows operation if said second operator is logged off and said paper path is clear.

11. An apparatus according to claim 1, wherein said output is electronic image output stored in said image producing device.

12. A method of preventing unauthorized disclosures of sensitive documents in an image producing device having a paper path, said method comprising the steps of:

determining access rights of a first operator, said access rights indicating an access level of said first operator;

sensing whether output from a previous job is present in said paper path;

preventing operation of said image producing device if output is present in said paper path and if said access level is less than a predetermined level; and

inhibiting clearing of said output from a previous job from said paper path if said access level is less than said predetermined level.

13. A method according to claim 12, further comprising the step of automatically purging said output in said paper path if said access level is higher than said predetermined level.

14. A method according to claim 13, wherein said automatically purging step comprises the step of directing said output to a waste box.

15. A method according to claim 13, wherein said image producing device comprises a finishing device for finishing output of said image producing device, said automatically purging step comprising the step of directing said output to said finishing device.

16. A method according to claim 13, further comprising the step of recording an operator password if said first operator is logged off and output is present in said paper path.

17. A method according to claim 13, further comprising the step of enabling login of a second operator if the access level of said first operator is less than said predetermined level.

18. A method according to claim 17, further comprising the step of automatically purging said output in said paper path if an access level of said second operator is higher than said predetermined level.

19. A method according to claim 18, further comprising the step of preventing operation of said image producing device while both the first and second operators are logged in.

20. A method according to claim 19, further comprising the step of allowing operation of said image producing device if said second operator is logged off and said paper path is clear.

21. A method of preventing unauthorized disclosures of sensitive information in an image producing device, said method comprising the steps of:

determining access rights of an operator, said access rights indicating an access level of said operator;

sensing whether electronic image output from a previous job is present in said image producing device;

preventing operation of said image producing device if electronic image output is present in said image producing device; and

inhibiting clearing of said output from a previous job from said image producing device if said access level is less than a predetermined level.

22. An apparatus for preventing unauthorized disclosures of sensitive information in an image producing device having a plurality of output bins, said apparatus comprising:

means for determining identification information of said operator;

means for determining access rights of said operator;

means for directing said output of said image producing device to a specific one of said plurality of output bins based on said identification information of said operator;

sensing means for sensing whether output from a previous job is present in said image producing device;

means for preventing operation of said image producing device in response to signals from said sensing means and said operator access rights; and

means for automatically purging said output from a previous job in said image producing device in response to said signals from said sensing means and said operator access rights, wherein said means for automatically purging comprises means for directing said output to an additional output bin separate from said plurality of output bins.

23. A method of preventing unauthorized disclosures of sensitive information in an image producing device having a plurality of output bins, the method comprising the steps of:

determining identification information of said operator;

determining access rights of said operator;

directing said output of said image producing device to a specific one of said plurality of output bins based on said identification information of said operator;

sensing whether output from a previous job is present in said image producing device;

preventing operation of said imaging producing device in response to signals from said sensing means and said operator access rights; and

automatically purging said output from a previous job in said image producing device in response to said signals from said sensing means and said operator access rights, wherein said means for automatically purging comprises means for directing said output to an additional output bin separate from said plurality of output bins.
