(50) A registration procedure of the paper type information history of the tray setting information will be described based on a flow chart of FIG. 8. The control unit controls and executes the following procedure.

(51) The control unit waits for the start of paper feed (step s1). If the paper feed is started (step s1, Yes), the control unit checks the setting information of the paper feed tray (step s2). The control unit determines whether the paper type information of the paper feed tray is the same as the head (latest) of the history information (step s3). The latest paper type information is registered from No. 1 as a history in the history information, and the paper type information is compared to the head information to determine whether to register the paper type information of the tray. If the paper type information is the same as the head (latest) of the history information (step s3, Yes), the control unit ends the process.

(52) If the paper type information is not the same as the head (latest) of the history information (step s3, No), the control unit registers the paper type information of the tray at the head of the history information of the tray that has fed the paper. The latest paper type information is registered from No. 1 as a history in the history information. If the number of registered histories exceeds the limit (for example: 10), older information is deleted to change No. 9 to No. 10, No. 8 to No. 9, . . . and No. 1 to No. 2. The latest information is registered in No. 1.

(53) A procedure of paper type information control in the setting information of the paper feed tray will be described based on a flow chart of FIG. 9. The control unit controls and executes the following procedure.

(54) The control unit starts the procedure when the tray setting screen is opened. When a change tray is selected (step s10), the control unit determines whether a history read (call) button is turned on (step s11). If the button is not turned on (step s11, No), the control unit determines that setting call is turned on and proceeds to a procedure of No. 1 in a flow chart of FIG. 10 (step s20).

(55) If the history read (call) button is turned on (step s11, Yes), the control unit calls the history information of the selected tray (step s12). After the call, the control unit displays a list of the history information on the operation display unit 140 (step s13) to allow selection of a history file and receives an operation input (step s14). After the reception of the operation input, the control unit determines whether the setting registration button is turned on (step s15). If the setting registration button is turned on (step s15, Yes), the control unit registers the selected history information in the paper profile (step s16) and ends the procedure.

(56) If the setting registration button is not turned on (step s15, No), the control unit determines whether the OK button is turned on (step s17). If the OK button is turned on (step s17, Yes), the control unit stores the selected history information in the paper type information of the selected tray (step s18) and ends the procedure.

(57) If the OK button is not turned on (step s17, No), the control unit determines whether the cancel button is turned on (step s19). If the cancel button is turned on (step s19, Yes), the control unit ends the procedure. If the cancel button is not turned on (step s19, No), the control unit returns to step s15 and repeats the determination of whether the setting registration button is turned on.

(58) A procedure when the setting call is turned on will be described based on the flow chart of FIG. 10. The control unit controls and executes the following procedure.

(59) The control unit determines whether the display button (check) of the record profiles of the current tray is turned on (step s20). If the display button is turned on (step s20, Yes), the control unit calls the paper profiles with use records of the selected tray (step s21). If the display button is not turned on, the control unit determines that the display buttons of all paper profiles are turned on and calls all paper profiles (step s22).

(60) After step s21 or step s22, the control unit displays the paper profile list on the operation display unit 140 (step s23). The operator selects a paper profile (step s24), and the control unit determines whether the OK button is turned on (step s25). If the OK button is turned on (step s25, Yes), the control unit stores the selected paper profile in the paper type information of the selected tray (step s26) and moves to the procedure of No. 2 in FIG. 9. If the OK button is not turned on (step s25, No), the control unit determines whether the cancel button is turned on (step s27). If the cancel button is turned on (step s27, Yes), the control unit moves to the procedure of No. 2 in FIG. 9. If the cancel button is not turned on (step s27, No), the control unit returns to step s25 and repeats the determination of whether the OK button is turned on.

(61) According to the present embodiment, the paper type information can be easily reset in the setting information of the paper feed tray.

(62) Although the present invention has been described based on the embodiment, the present embodiment can be appropriately changed without departing from the scope of the present invention.
