EXPENDABLE SUPPLY FOR PRINTER
First Claim
1. An expendable supply configured to be replaceably installed in a printer and to be used in a printing operation of the printer,wherein the printer comprisesa detector that detects at least one of a power-on operation of the printer, a resume operation from an energy-saving mode of the printer and an installation of the expendable supply,a determiner that determines whether or not a recommended limit of the expendable supply has passed, based on a production date or a usage start date of the expendable supply, the recommended limit set before a usable limit of the expendable supply, and an elapsed date from the production date or the usage start date,a warning generator that generates a warning for notifying that the usable limit of the expendable supply is approaching, when the determiner determines that the recommended limit of the expendable supply has passed, anda memory storage that stores a warning cycle including a first time period and a second time period after the first time period,wherein the expendable supply comprises:
- a memory that stores a timing of a last warning generation after the recommended limit,wherein, upon determination by the determiner that the recommended limit has passed and upon detection by the detector of the power-on operation, the resume operation from the energy-saving mode, or the installation of the replacement expendable supply, the warning generator determines whether to generate a warning,wherein, in determining whether to generate a warning, the warning generator;
determines to generate a warningupon the timing of the last warning generation being not yet stored in the memory of the expendable supply at the detection by the detector of the printer, orupon the timing of the last warning generation included in the first time period being already stored in the memory of the expendable supply at the detection by the detector of the printer and the first time period having elapsed at the detection by the detector of the printer; and
determines not to generate a warning upon the timing of the last warning generation included in the first time period being already stored in the memory of the expendable supply at the detection by the detector of the printer and the first time period having not elapsed at the detection by the detector of the printer, andwherein the warning generator;
generates a warning upon determination to generate a warning; and
does not generate a warning upon determination not to generate a warning.

Abstract
An expendable supply includes a memory that stores a timing of a last warning after a recommended limit. A warning generator of a printer determines whether to generate a warning upon occurrence of certain operations. The warning generator generates a warning when the last warning generation time is not stored in the memory of the expendable supply upon detection by a printer detector, or upon the last warning generation included in a first time period is stored in the expendable supply memory at the detection by the detector and the first time period has elapsed at the detection by the detector. A warning is not generated upon the timing of the last warning generation included in the first time period is already stored in the expendable supply memory upon detection by the detector and the first time period having not elapsed at the detection by the detector.

1. An expendable supply configured to be replaceably installed in a printer and to be used in a printing operation of the printer,
wherein the printer comprises a detector that detects at least one of a power-on operation of the printer, a resume operation from an energy-saving mode of the printer and an installation of the expendable supply, a determiner that determines whether or not a recommended limit of the expendable supply has passed, based on a production date or a usage start date of the expendable supply, the recommended limit set before a usable limit of the expendable supply, and an elapsed date from the production date or the usage start date, a warning generator that generates a warning for notifying that the usable limit of the expendable supply is approaching, when the determiner determines that the recommended limit of the expendable supply has passed, and a memory storage that stores a warning cycle including a first time period and a second time period after the first time period, wherein the expendable supply comprises: - a memory that stores a timing of a last warning generation after the recommended limit,
wherein, upon determination by the determiner that the recommended limit has passed and upon detection by the detector of the power-on operation, the resume operation from the energy-saving mode, or the installation of the replacement expendable supply, the warning generator determines whether to generate a warning, wherein, in determining whether to generate a warning, the warning generator; determines to generate a warning upon the timing of the last warning generation being not yet stored in the memory of the expendable supply at the detection by the detector of the printer, or upon the timing of the last warning generation included in the first time period being already stored in the memory of the expendable supply at the detection by the detector of the printer and the first time period having elapsed at the detection by the detector of the printer; and determines not to generate a warning upon the timing of the last warning generation included in the first time period being already stored in the memory of the expendable supply at the detection by the detector of the printer and the first time period having not elapsed at the detection by the detector of the printer, and wherein the warning generator; generates a warning upon determination to generate a warning; and does not generate a warning upon determination not to generate a warning. - View Dependent Claims (2, 3, 4, 5)

6. An expendable supply configured to be replaceably installed in a printer that carries out a printing operation, and to be used in the printing operation, wherein the printer comprises
a detector that detects at least one of a power-on operation of the printer, a resume operation from an energy-saving mode of the printer and an installation of the expendable supply, a determiner that determines whether or not a recommended limit of the expendable supply has passed, based on a production date or a usage start date of the expendable supply, the recommended limit set before a usable limit of the expendable supply, and an elapsed date from the production date or the usage start date, a warning generator that generates a warning for notifying that the usable limit of the expendable supply is approaching, when the determiner determines that the recommended limit of the expendable supply has passed, and a memory storage that stores a warning cycle that is an interval between two warning generations, the expendable supply comprising: -
a memory that stores a timing of a last warning generation after the recommended limit, wherein the memory of the expendable supply stores the warning cycle that is provided as an integral multiple of a first preset period, and the memory storage of the printer stores a second preset period that is set shorter than the first preset period, and wherein, when the determiner of the printer determines that the recommended limit has passed and the power-on operation, the resume operation from the energy-saving mode or the installation of the expendable supply is detected by the detector of the printer, the warning generator of the printer generates a warning [1] when the timing of the last warning generation is not yet stored in the memory of the expendable supply, or [2] when the timing of the last warning generation is already stored in the memory of the expendable supply, the warning cycle has elapsed from the last warning generation and the second preset period has elapsed in the first preset period at a current timing.
