Image forming apparatus mounted with replaceable unit, image forming system, and method of controlling image forming apparatus
First Claim
1. An image forming apparatus comprising:
- an image forming apparatus main body,at least one replaceable unit replaceably mounted in the image forming apparatus main body,a discriminating unit that discriminates whether or not the replaceable unit is a genuine article,an input unit for selecting any one of an operation mode corresponding to a replaceable unit which is a genuine article and other operation modes, different from the operation mode, corresponding to a replacement unit that is other than a genuine article, anda control unit that performs control in an operation mode selected by the input unit that improves an image quality and/or an operational performance achieved with a replacement unit other than a genuine article.

Abstract
In the case of being mounted with any cartridge other than a genuine cartridge, which accommodates a toner other than a genuine toner, a user can select as an operation mode other than that corresponding to a genuine toner, through a UI device 18, making a correction to the consumption of a developer by combining conditions to be changed, such as increasing or decreasing the degree of a change (gradient) in a set value of the toner density with respect to the consumption of a developer (m1 or m2); increasing or decreasing a limit value (m1 or m2); varying an initial value (consumption=0) (m3); no making a change in a set value according to the consumption (m4); and no making a change in a set value according to the consumption, for example, by varying an initial value (m5)

8. An image forming system comprising:
-
an image forming apparatus, and a host apparatus connected to the image forming apparatus, the image forming apparatus having; an image forming apparatus main body, at least one replaceable unit replaceably mounted in the image forming apparatus main body, a discriminating unit that discriminates whether or not the replaceable unit is a genuine article, and a control unit that performs control in an operation mode selected, the host apparatus having an input unit for selecting any one of an operation mode corresponding to a replaceable unit which is a genuine article and other operation modes different from the operation mode, corresponding to a replacement unit that is other than a genuine article, wherein the control unit performs control in a selected operation mode corresponding to a replacement unit that is other than a genuine article to improve an image quality and/or an operational performance achieved with a replacement unit other than a genuine article.

9. A method of controlling an image forming apparatus in which at least one replaceable unit is mounted in an image forming apparatus main body, the method comprising:
-
discriminating whether or not the mounted replaceable unit is a genuine article, waiting until a user selects an operating mode after performing display that urges the user to select an operation mode, corresponding to a replacement unit that is other than a genuine article, and performing control in an operation mode corresponding to input by the user, if the user inputs the operation mode, that improves an image quality and/or an operational performance achieved with a replacement unit other than a genuine article.

11. A method of controlling an image forming apparatus in which at least one replaceable unit is mounted in an image forming apparatus main body, the method comprising:
-
detecting that the replaceable unit has been mounted in the image forming apparatus main body, discriminating whether or not the mounted replaceable unit is a genuine article, waiting until a user selects an operating mode after performing display that urges the user to select an operation mode corresponding to a replacement unit that is other than a genuine article, and performing control in an operation mode corresponding to input by the user, if the user inputs an operation mode corresponding to a replacement unit that is other than a genuine article, that improves an image quality and/or an operational performance achieved with a replacement unit other than a genuine article.
