Image forming apparatus and control method
An image forming apparatus includes an authentication section configured to execute an authentication process on a replacement part; and a controller configured to skip the authentication process when determining that a stop period from the start of operation stop to the end or the operation stop is equal to or shorter than a predetermined period of time, and to execute the authentication process when determining that the stop period exceeds the predetermined period of time.
1. An image forming apparatus, comprising:
an image forming section configured to form an image on a sheet;
a fixing section configured to heat the sheet;
an authentication section configured to execute an authentication process on a replacement part; and
a controller configured to control the heating operation of the fixing section, to skip the authentication process when determining that a stop period from the start of the heating operation stop to the end of the heating operation stop is equal to or shorter than a predetermined period of time, and to execute the authentication process when determining that the stop period exceeds the predetermined period of time.
2. The image forming apparatus according to claim 1 , wherein the replacement part is one of a toner cartridge, an inkjet cartridge, an inkjet head or a waste ink tank.
3. The image forming apparatus according to claim 1 , wherein the controller is configured to use an acquired time to determine whether or not the stop period is equal to or shorter than a predetermined period of time.
4. The image forming apparatus according to claim 1 , wherein when the authentication is not successful, the controller is configured to issue an error notification.
5. The image forming apparatus according to claim 1 , wherein when the authentication is successful, the controller is configured to issue a notification indicating that the authentication is successful.
6. The image forming apparatus according to claim 1 , further comprising:
a storage configured to store the temperature of the fixing section at the start of the heating operation stop, Wherein
the controller is configured to determine that the stop period is equal to or shorter than a predetermined period of time when a difference between the temperature stored in the storage and the temperature of the fixing section at the end of the heating operation stop is equal to or smaller than a predetermined value.
7. An image forming apparatus, comprising:
an image forming section configured to form an image on a sheet;
a fixing section configured to heat the sheet:
an authentication section configured to execute an authentication process on a plurality of replacement parts used in the image forming section: and
a controller configured to control the heating operation of the fixing section, to start the authentication process on the replacement part determined to be used in a job to be executed at the end of the heating operation stop prior to the authentication process on other replacement parts determined not to be used in the job.
8. A control method, comprising:
performing a heat operation, via a fixing section, to heat a sheet;
controlling the heating operation, to skip an authentication process on a replacement part when it is determined that a stop period from the start of the heating operation stop to the end of the heating operation stop is equal to or shorter than a predetermined period of time, and
executing the authentication process when it is determined that the stop period exceeds the predetermined period of time.
9. The control method of claim 8 , wherein determining whether or not the stop period is equal to or shorter than a predetermined period of time is based on an acquired time.
10. The control method of claim 8 , further comprising storing the temperature of the fixing section at the start of the heating operation stop,
wherein it is determined that the stop period is equal to or shorter than a predetermined period of time when a difference between the stored temperature and the temperature of the fixing section at the end of the heating operation stop is equal to or smaller than a predetermined value.
11. The control method of claim 8 , further comprising: when the authentication is not successful, issuing an error notification.
12. The control method of claim 8 , further comprising: when the authentication is successful, issuing a notification indicating that the authentication is successful.
13. A control method, comprising:
forming an image on a sheet via an image forming section;
performing a heating operation, via a fixing section, to heat the sheet;
executing an authentication process on a plurality of replacement parts used in the image forming section; and
controlling the heating operation of the fixing section, to start the authentication process on the replacement part determined to be used in a job to be executed at the end of a heating operation stop prior to the authentication process on other replacement parts determined not to be used in the job.
