Abstract

A printer, fax machine, copier, scanner, or any other office device used by multiple users from multiple locations is provided with improved apparatus and/or software for locking out all incoming commands from reaching the device'"'"'s internal controller except for commands coming from a newly-designated primary controller used by the service technician. This lockout can be used with any type of office machine that has it'"'"'s own internal controller, so it applies equally to all types of office machines and systems generally used in today'"'"'s office environments.

Claims

1. A printer comprising:

a host interface operable to receive print jobs from a user;

a print controller; and

a service interface operable to monitor for a service mode activation signal from a service technician, and further operable to provide the service mode activation signal to the print controller in response to receiving the service mode activation signal from the service technician,

wherein the print controller is operable to disable the host interface to block the reception of the print jobs from the user in response to receiving the service mode activation signal from the service interface, to notify the user that the host interface is disabled, and to enable control of the printer through the service interface by the service technician.

2. The printer of claim 1 wherein:

the service interface is further operable to terminate providing the service mode activation signal to the print controller in response to determining that the service technician has terminated the service mode activation signal, and

the print controller is further operable to enable the host interface to receive the print jobs from the user in response to the termination of the service mode activation signal, and to disable control of the printer through the service interface.

3. The printer of claim 2 wherein the print controller is further operable to notify the user that the host interface is enabled in response to the termination of the service mode activation signal.

4. The printer of claim 1 wherein the service interface comprises a keypad operable to receive the service mode activation signal from the service technician.

5. The printer of claim 1 wherein the service interface comprises a wireless interface operable to receive the service mode activation signal from a device external to the printer.

6. The printer of claim 1 wherein the print controller is further operable to ignore the service mode activation signal while the print controller is processing the print jobs from the user.

7. A method operable on a print controller of a printer, the method comprising:

monitoring a host interface of the printer for print jobs from a user;

monitoring a service interface of the printer for a service mode activation signal from a service technician; and

responsive to receiving the service mode activation signal from the service interface, disabling the host interface to block the reception of the print jobs from the user, notifying the user that the host interface is disabled, and enabling control of the printer through the service interface by the service technician.

8. The method of claim 7 further comprising:

determining that the service technician has terminated the service mode activation signal; and

responsive to the termination of the service mode activation signal, disabling the control of the printer through the service interface, and enabling the host interface to receive the print jobs from the user.

9. The method of claim 8 further comprising:

notifying the user that the host interface is enabled in response to the termination of the service mode activation signal.

10. The method of claim 7 wherein monitoring the service interface further comprises:

monitoring a keypad of the printer for the service mode activation signal from the service technician.

11. The method of claim 7 wherein monitoring the service interface further comprises:

monitoring a wireless interface of the printer for the service mode activation signal from a device external to the printer.

12. The method of claim 7 further comprising:

determining that the print controller is processing the print jobs from the user; and

ignoring the service mode activation signal in response to the determination.

13. A computer readable medium tangibly embodying programmed instructions which, when executed by a print controller of a printer, are operable for performing a method, the method comprising:

monitoring a host interface of the printer for print jobs from a user;

monitoring a service interface of the printer for a service mode activation signal from a service technician; and

responsive to receiving the service mode activation signal from the service interface, disabling the host interface to block the reception of the print jobs from the user, notifying the user that the host interface is disabled, and enabling control of the printer through the service interface.

14. The computer readable medium of claim 13, wherein the method further comprises:

determining that the service technician has terminated the service mode activation signal; and

responsive to the termination of the service mode activation signal, disabling the control of the printer through the service interface, and enabling the host interface to receive the print jobs from the user.

15. The computer readable medium of claim 14, wherein the method further comprises:

notifying the user that the host interface is enabled in response to the termination of the service mode activation signal.

16. The computer readable medium of claim 13, wherein the method further comprises:

monitoring a keypad of the printer for the service mode activation signal from the service technician.

17. The computer readable medium of claim 13, wherein the method further comprises:

monitoring a wireless interface of the printer for the service mode activation signal from a device external to the printer operated by the service technician.

18. The computer readable medium of claim 13, wherein the method further comprises:

determining that the print controller is processing the print job from the user; and

ignoring the service mode activation signal responsive to the determination.
