Reserve life run-on feature for customer replaceable units
View Patent ↗A printer includes at least one replaceable module which is removable from the printer. A processor discontinues an operation of the printer when the processor determines that an end of life value for the replaceable module is reached unless an appropriate identifier is input which allows the operation of the printer to continue beyond the end of life value. The identifier may be provided by a supplier at the end of life point, provided that an order for a replacement module is received.
1. A printer comprising:
at least one replaceable module which is removable from the printer; and
a processor having a first mode of operation which discontinues an operation of the printer when the processor determines that an end of life value for the replaceable module is reached and a second mode of operation which allows the operation of the printer to continue beyond the end of life value in response to the input of an identifier which the processor recognizes as invoking the second mode of operation, the identifier comprising a password.
2. The printer of claim 1 , further comprising a graphical user interface in communication with the processor which displays instructions to a user for obtaining the identifier.
3. The printer of claim 2 , wherein the graphical user interface is configured for communicating the identifier to the processor in response to user inputting the identifier to the graphical user interface.
4. The printer of claim 1 , wherein the end of life value comprises a maximum number of prints to be created by the replaceable module in the first mode of operation.
5. The printer of claim 4 , wherein in the second mode of operation, the processor allows a limited number of prints in excess of the maximum number of prints.
6. The printer of claim 1 , wherein the replaceable module comprises at least one of an imaging unit and a fuser unit.
7. The printer of claim 1 , wherein the replaceable module comprises a memory which stores the end of life value.
8. A printer comprising:
at least one replaceable module which is removable from the printer; and
a processor having a first mode of operation which discontinues an operation of the printer when the processor determines that an end of life value for the replaceable module is reached and a second mode of operation which allows the operation of the printer to continue beyond the end of life value in response to the input of an identifier which the processor recognizes as invoking the second mode of operation; and
a graphical user interface in communication with the processor which displays instructions to a user for obtaining the identifier, the instructions displayed requiring that the user places an order for a replacement replaceable module for the identifier to be communicated to the user.
9. The printer of claim 8 , wherein the identifier comprises a password.
10. A printer comprising:
at least one replaceable module which is removable from the printer; and
a processor having a first mode of operation which discontinues an operation of the printer when the processor determines that an end of life value for the replaceable module is reached and a second mode of operation which allows the operation of the printer to continue beyond the end of life value in response to the input of an identifier which the processor recognizes as invoking the second mode of operation, wherein the processor does not accept the identifier as invoking the second mode until the end of life value is reached.
11. A method of operating a printer comprising:
storing an end of life value of a printing parameter for a replaceable module of a printer in memory;
in a first mode, discontinuing an operation of the printer when the printing parameter reaches the end of life value;
in a second mode, continuing the operation of the printer beyond the end of life value in response to the input of an identifier which is recognized as invoking the second mode of operation, the identifier being provided to a user when a replacement replaceable module is ordered.
12. The method of claim 11 , wherein the method further comprising providing instructions to a user for obtaining the identifier when the end of life value is reached.
13. The method of claim 11 , further comprising, in the first mode, incrementing the printing parameter as the replaceable module creates prints.
14. The method of claim 11 , wherein the method further comprises receiving the identifier from a user via a graphical user interface associated with the printer.
15. The method of claim 11 , wherein the end of life value comprises a maximum number of prints to be created by the replaceable module in the first mode of operation.
16. The method of claim 15 , wherein in the second mode of operation, only a limited number of prints in excess of the maximum number of prints is permitted to be printed.
17. The method of claim 11 , wherein the replaceable module comprises at least one of an imaging unit and a fuser unit.
18. A method of operating a printer comprising:
storing an end of life value of a printing parameter for a replaceable module of a printer in memory;
in a first mode, discontinuing an operation of the printer when the printing parameter reaches the end of life value;
in a second mode, continuing the operation of the printer beyond the end of life value in response to the input of an identifier which is recognized as invoking the second mode of operation, the second mode being invoked only when the end of life value is reached.
19. A computer program product which stores instructions for implementing the method of claim 18 .
20. A printer comprising a processor which implements the method of claim 18 and at least one replaceable module.
21. A method of operating a printer comprising:
storing an end of life value of a printing parameter for a replaceable module of a printer in memory;
incrementing a cumulative value of the printing parameter with a processor as the replaceable module creates prints;
when the cumulative value of the parameter reaches a value which is close to the end of life value, providing a reorder notification;
requiring that a user places an order for a replacement replaceable module for an identifier to be communicated to the user; and
if the replaceable module is not replaced before the cumulative value reaches the end of life value, determining whether the identifier has been input, and if the identifier has been input, permitting the replaceable module to continue to create prints until a reserve life value is reached.
